Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

• User memory MVP (#489–#493) — opt-in persistent note file injected into the system prompt as a <user_memory> block.
  • # foo typed in the composer appends a timestamped bullet without firing a turn (#492).
  • /memory [show|path|clear|edit] slash command for inline inspection / editing hints (#491).
  • remember model-callable tool so the agent can capture durable preferences itself; auto-approved because writes are scoped to the user's own file (#489).
  • Hierarchy loader pulls ~/.deepseek/memory.md (path configurable via memory_path / DEEPSEEK_MEMORY_PATH) and injects above the volatile-content boundary in the prompt (#490).
  • Default off; enable with [memory] enabled = true or DEEPSEEK_MEMORY=on (#493).
  • Full feature documentation in docs/MEMORY.md.
• Inline diff rendering for edit_file / write_file (#505) — tool results now emit a unified diff at the head of the body, picked up by the existing diff-aware renderer with line numbers and coloured +/- gutters. New similar crate dep.
• OSC 8 hyperlinks (#498) — URLs in the transcript become Cmd+click-openable in supporting terminals (iTerm2, Terminal.app 13+, Ghostty, Kitty, WezTerm, Alacritty). Clipboard path strips the escapes so yanked text stays clean. Off-switch: [tui] osc8_links = false.
• Retry/backoff visual countdown (#499) — ⟳ retry N in Ms — reason banner ticks down during HTTP backoff. On exhaustion the row turns red × failed: <reason> until the next turn starts.
• MCP server health chip (#502) — colour-coded MCP M/N in the footer's right-cluster: success / warning / error / muted by reachability. Hidden when zero MCP servers are configured.
• Per-project config overlay (#485) — <workspace>/.deepseek/config.toml now overlays nine fields on top of the user-global config: provider, model, api_key, base_url, reasoning_effort, approval_policy, sandbox_mode, mcp_config_path, notes_path, max_subagents, allow_shell. Pass --no-project-config to bypass for one launch.
• Sub-agent role taxonomy expansion (#404) — adds Implementer ("land this change with the minimum surrounding edit") and Verifier ("run the test suite, report pass/fail with evidence") to the existing general / explore / plan / review / custom set. Each role has a distinct system prompt posture. Documented in docs/SUBAGENTS.md.
• docs/SUBAGENTS.md — full sub-agent reference: role taxonomy, alias map, concurrency cap, lifecycle, session-boundary classification, output contract.
• docs/MEMORY.md — user-facing memory feature documentation.
• Competitive analysis doc — docs/COMPETITIVE_ANALYSIS.md catalogues capability matrix vs OpenCode and Codex CLI.
• Session prune helper + /sessions prune <days> (#406 phase-1) — drops persisted sessions older than N days from ~/.deepseek/sessions/. Skips the checkpoint subdirectory and compares against metadata updated_at (not fs mtime, which can lie after an rsync). 10 total tests cover the helper's contract and the slash-command dispatch surface. Phase 2 (boot-prune + retention policy) stays v0.8.9 work.
• deepseek doctor --json now surfaces a memory block (enabled / path / file_present) so operators can verify memory configuration without booting the TUI.
• Tool-output spillover (#422 + #423 + #500) — tool outputs over 100 KiB now spill to ~/.deepseek/tool_outputs/<id>.txt from the engine's tool-execution path. The model receives a 32 KiB head plus a footer pointing at the spillover file (Use read_file path=…), the tool cell renders an inline full output: <path> annotation in live mode, and a 7-day boot prune keeps the directory bounded. Spillover is skipped on error results so the model still sees the failure message verbatim. The existing tool-details pager surfaces the truncated head so the user can verify what the model saw.

Changed

• Sub-agent concurrency cap raised to 10 by default (#509) — was 5; configurable via [subagents].max_concurrent (hard ceiling 20). Running-count now ignores non-running, no-handle, and finished handles so completed agents stop occupying slots.
• SharedSubAgentManager is Arc<RwLock<...>> (#510) — read paths take read locks, eliminating the multi-agent fan-out UI freeze.
• Sub-agent output summarized before parent context (#511) — compact_tool_result_for_context now compresses agent_result / agent_wait payloads instead of dumping the full snapshot back into the parent's context window.
• agent_list defaults to current-session view (#405) — each manager mints a session_boot_id and stamps every spawn; agents loaded from prior sessions are filtered unless include_archived=true is passed. Each result carries a from_prior_session flag.
• Concise todo / checklist update rendering (#403) — repeat todo_update / checklist_update calls render a one-line Todo #N: <title> → STATUS card with full list still reachable via Alt+V instead of dumping the entire item array on every call.
• Compact agent_spawn rendering (#409) — the generic tool block for agent_spawn collapses to one header line in live mode (◐ delegate · agent-abc12 [running]) since the DelegateCard already owns live action progress. Transcript replay keeps the full block.
• Plan panel role clarified (#408) — drops the "No active plan" placeholder when the panel is otherwise empty; documents the panel's narrow role (update_plan tool output + /goal + cycle counter, distinct from todos).
• Sub-agent description copy — agent_spawn tool description and prompts/base.md updated to reflect the new default cap of 10 (was stale "Max 5 in flight").
• agent_spawn / agent_assign schema descriptions (#404 follow-up) — type/agent_name property descriptions now list implementer and verifier so the model surfaces those roles without having to discover them from docs/SUBAGENTS.md. Adds the long-form aliases (builder / validator / tester) on agent_assign for parity with the alias map.
• Multi-day duration formatting (#447) — humanize_duration now caps at two units and promotes through h/d/w boundaries. Long-running sessions render as 2d 3h instead of 188415s, and the previous "192m 30s" cycle output becomes 3h 12m. The /goal status line picks up the same formatter so multi-day goal-elapsed times stay readable.
• Accessibility flag (#450) — NO_ANIMATIONS=1 env var now forces low_motion = true and fancy_animations = false at startup, regardless of the saved settings.toml. Recognises the standard truthy spellings (1, true, yes, on). Documented end-to-end in the new docs/ACCESSIBILITY.md, including the existing low_motion / calm_mode / show_thinking / show_tool_details toggles for screen-reader users.
• Cumulative session-elapsed footer chip (#448) — a low-priority worked 3h 12m chip in the footer's right cluster shows session age once it crosses 60s. Hidden during the first minute of a launch so a fresh start doesn't flash a ticker. Drops first under narrow widths so the existing chips (coherence / agents / replay / cache / mcp) keep their slots. Sampled at props-build time (matches the retry capture pattern) so render stays pure for tests.
• instructions = [...] config array (#454) — declare additional instruction files (./AGENTS.md, ~/.deepseek/global.md, …) and they're concatenated into the system prompt in declared order, above the skills block. Each file is capped at 100 KiB; missing files log a warning and are skipped instead of failing the launch. Project config replaces the user-level array wholesale (the typical "merge" pattern is for users who want both — they list ~/global.md inside the project array). Documented in config.example.toml.
• Keyboard-enhancement flags pop on suspend paths too (#443 follow-up) — pause_terminal (Ctrl+Z / shell-suspend) and external_editor::spawn_editor_for_input (composer $EDITOR launch) now pop the flags before handing the terminal to the child process, matching the existing shutdown and panic-hook paths. Defense-in-depth: if a future code path enables the flags explicitly, the suspend handlers won't leak them to a Vim / less / shell child that hasn't asked for them.
• load_skill tool (#434) — model-callable tool that takes a skill id and returns the SKILL.md body plus the sibling companion-file list in one call. Faster than the existing read_file + list_dir dance; surfaces the skill's description as a quote block at the head so a single tool result is self-contained. Resolves the skills directory with the same hierarchy App::new uses (.agents/skills → skills → ~/.deepseek/skills). Available in Plan and Agent/Yolo modes.
• Kitty keyboard protocol opt-in (#442) — pushes DISAMBIGUATE_ESCAPE_CODES at startup so terminals that support the protocol (Kitty, Ghostty, Alacritty 0.13+, WezTerm, recent Konsole / xterm) report unambiguous events for Option/Alt-modified keys, plain Esc, and multi-byte sequences. Legacy terminals silently discard the escape and see no change. Only the disambiguation tier is pushed — release-event reporting was deliberately skipped because the existing handlers would mis-route releases as duplicate presses. The flags are popped on shutdown / panic / suspend paths (#443).
• Multi-directory skill discovery (#432) — the system prompt's ## Skills listing and the load_skill tool now walk every candidate directory in the workspace plus the global default: <workspace>/.agents/skills → <workspace>/skills → <workspace>/.opencode/skills → <workspace>/.claude/skills → ~/.deepseek/skills. Skills installed for any AI-tool convention show up in the same catalogue. Name conflicts resolve first-match-wins per the precedence order so workspace-local skills shadow user/global ones. New skills_directories() and discover_in_workspace() helpers in crates/tui/src/skills/mod.rs.
• tool.spillover audit event (#500 polish) — emit a discrete audit-log entry whenever apply_spillover writes a spillover file, so operators tailing ~/.deepseek/audit.log can correlate large-output episodes with disk-usage growth in ~/.deepseek/tool_outputs/. Fires in both the sequential and parallel tool paths.
• Prompt stash (#440) — Ctrl+S in the composer parks the current draft to a JSONL-backed stash at ~/.deepseek/composer_stash.jsonl (no-op on empty composer). /stash list shows parked drafts (oldest first, with one-line previews and timestamps); /stash pop restores the most recently parked draft into the composer (LIFO). Self-healing parser drops malformed lines instead of poisoning the stash. Capped at 200 entries; multiline drafts round-trip intact via JSON's newline escaping.
• RLM tool family (#512) — rlm tool cards map to ToolFamily::Rlm and render rlm, not swarm. Stale "swarm" wording cleaned out of docs / comments / tests.
• Foreground RLM visible in Agents sidebar (#513 — stopgap) — projection now shows foreground RLM work; full async lifecycle remains v0.8.9.

Fixed

• Don't auto-approve git -C ... (#416, shipped 2026-05-03) — v0.8.8 release runtime fix; foundation for the rest of the stabilization batch.
• Self-update arch mapping (#503) — update.rs uses release asset naming (arm64/x64) instead of raw Rust constants (aarch64/x86_64); rejects .sha256 siblings as primary binaries.
• Composer Option+Backspace deletes by word (#488) — was deleting by character.
• Offline composer queue is session-scoped (#487) — legacy unscoped queues fail closed instead of leaking content into unrelated chats.
• display_path test race + Windows separator (#506) — tests no longer mutate $HOME; display_path_with_home walks components and joins with MAIN_SEPARATOR_STR so Windows shows ~\projects\foo not ~\projects/foo.
• Footer reads statusline colours from app.ui_theme (#449) — was using a bespoke palette.
• Keyboard-enhancement flags pop on panic exit too (#443/#444) — raw-mode startup probe is now bounded by a configurable timeout.
• CI workflow cleanup (#507) — pruned three duplicated/dead workflows (crates-publish.yml, parity.yml, publish-npm.yml); release.yml build job now allows parity to be skipped on manual workflow_dispatch; release-runbook reconciled.

Releases

• npm wrapper publish remains manual (npm 2FA OTP requirement).
• GitHub release automation depends on RELEASE_TAG_PAT secret — without it auto-tag.yml creates the tag but release.yml doesn't fire.

[0.8.7] - 2026-05-03

Fixed

• Selection across transcript cell types — the selection-tightening from v0.8.6 (#383) restricted copy/select to user and assistant message bodies only, so text in system notes, thinking blocks, and tool output could not be copied. v0.8.7 removes the body-start gate; the rendered transcript block is fully selectable again.

[0.8.6] - 2026-05-03

Added

• Long-session survivability by default (#402) — capacity control and compaction defaults are enabled, transcript history is bounded, persisted sessions are capped, and oversized history folds into archived context placeholders instead of freezing the TUI.
• v0.8.6 feature batch (#373-#402) — adds Goal mode, cache-hit chips, cycle-boundary visualization, file-tree pane, /share, /model auto, user-defined slash commands, /profile, LSP diagnostic wiring, crash-recovery, self-update, /init, /diff, patch-aware /undo, /edit, inline diff highlighting, smart clipboard, native-copy escape, right-click context menus, clickable file:line styling, and MCP Phase A.

Fixed

• Lag and rendering regressions (#399, #400) — moves git/file-tree work off the UI thread where possible, bounds render history, and tightens redraw behavior to avoid sidebar/chat text bleed-through.
• Release-hardening follow-ups — /share now writes via secure temp files, self-update uses secure same-directory temps with Windows-safe replacement, and docs/rustfmt release gates are clean.

[0.8.4] - 2026-05-02

Added

• Localization expansion (Phase 1, #285) — every slash command's help description, the full /tokens / /cost / /cache debug output, the footer state and chip text, and the help-overlay section headings are now translated for all four shipped locales (en, ja, zh-Hans, pt-BR). Set the language with /config locale zh-Hans (or LANG=zh_CN.UTF-8 / LC_ALL=zh_CN.UTF-8 from the shell). Non-Latin scripts render via the same unicode_width plumbing the existing 27 chrome strings already use; the shipped_first_pack_has_no_missing_core_messages test enforces full coverage across all four locales for every new MessageId. Tool descriptions sent to the model and the base system prompt intentionally remain English (training-data alignment, prefix cache stability).
  • Phase 1a (#294): 44 new IDs covering slash commands.
  • Phase 1b (#295): 13 new IDs covering /tokens / /cost / /cache debug output. Templates use {placeholder} substitution so a translator can re-order args freely.
  • Phase 1c (#296): 11 new IDs covering footer state, sub-agent chip, quit-confirmation toast, and help-overlay section labels.
• Stable cache prefix (#263) — five companion fixes to keep the DeepSeek prefix cache stable across turns: drop volatile fields from the working-set summary block (#280, #287), place handoff and working-set after the static prompt blocks (#288 → #292), memoise the tool catalog so descriptions stay byte-stable (#289), sort project_tree and summarize_project output (#290), and use a unique fallback id for parallel streaming tool calls so downstream tool-result routing doesn't match the first call twice (#291). The combined effect is a meaningful jump in cache hit rate after the third turn.

Fixed

• Agent-mode shell exec could not reach the network (#272) — the seatbelt default policy denies all outbound network including DNS, so any exec_shell command needing the network (curl, yt-dlp, package managers, …) failed in Agent mode unless the user dropped to Yolo. The engine now elevates the sandbox policy to WorkspaceWrite { network_access: true, … } for both Agent and Yolo. Plan mode is unchanged (read-only investigation never registers the shell tool). The application-level NetworkPolicy (crates/tui/src/network_policy.rs) remains the only outbound-traffic boundary.
• /skill install <github-repo-url> failed with invalid gzip header (#269) — https://github.com/<owner>/<repo> parsed as a raw direct URL, so the installer downloaded the HTML repo page and tried to gzip-decode HTML. Bare GitHub repo URLs (with or without .git, with or without www., with or without a trailing slash) now route to the GitHubRepo source the same as github:<owner>/<repo>. URLs that already point at a specific archive / blob / tree path still go through DirectUrl.
• V4 Pro discount expiry extended (#267) — DeepSeek extended the V4 Pro 75% promotional discount from 2026-05-05 15:59 UTC to 2026-05-31 15:59 UTC. Without this update the TUI would have started showing 4× the actual billed cost on May 6 onwards. Verified at https://api-docs.deepseek.com/quick_start/pricing.

[0.8.3] - 2026-05-01

Fixed

• Skills prompt referenced fabricated paths — render_available_skills_context rendered each skill's file as <skills_dir>/<frontmatter-name>/SKILL.md, which did not exist when the directory name differed from the frontmatter name (community installs, manually-placed skills). Skill now carries the real path captured at discovery and renders that.
• Missing-companion error was hostile to direct GitHub Release downloaders (#258) — replaced "Build workspace default members to install it" wall of text with a concrete three-path checklist: npm install -g deepseek-tui, cargo install deepseek-tui-cli deepseek-tui --locked, or downloading both deepseek-<platform> AND deepseek-tui-<platform> from the same Release page. DEEPSEEK_TUI_BIN stays as a power-user fallback.

Added

• Privacy: $HOME contracts to ~ in viewer-visible paths — the TUI, deepseek doctor, deepseek setup, and onboarding now contract the home directory to ~ in every path shown on screen, so screenshots, screencasts, and pasted help output do not leak the OS account name. Persisted state, audit log, session checkpoints, and LLM-bound system prompts intentionally keep absolute paths for full fidelity.
• crates.io badge alongside the CI and npm badges in both English and Simplified Chinese READMEs.
• Engine decomposition (#227) — core/engine.rs is split into focused submodules (engine/{streaming,turn_loop,dispatch,tool_setup,tool_execution,tool_catalog,context,approval,capacity_flow,lsp_hooks,tests}.rs). No behavior change; preparation for the future agent-loop work.

Tests

• RLM bridge: batch_guard extracted and tested for the empty-batch and oversize-batch invariants; depth-guard fallback covered (partial #231).
• Persistence: schema-version rejection covered for load_session, load_offline_queue_state, runtime_threads::load_turn, runtime_threads::load_item (partial #233).
• Command palette: [disabled] server description tag (closes the remaining #197 acceptance gap).
• Protocol-recovery contract tests now scan the engine submodules in addition to engine.rs so the decomposition refactor doesn't silently hide the fake-wrapper marker assertions.

Issue triage

• 10 issues closed with verification commits cited (#247, #235, #197, #250, #234, #243, #238, #236, #239, #195).

[0.8.2] - 2026-05-01

Fixed

• Windows release build (LNK1104) — drop the deepseek shim binary in crates/tui that 0.8.1 introduced for the bundled cargo install. It produced a second target/release/deepseek.exe that collided with the deepseek-tui-cli artifact during workspace builds; the second linker invocation hit LNK1104: cannot open file deepseek.exe on Windows. The cli crate is now the single source of deepseek; workspace default members still produce both binaries (one per crate).
• npm wrapper offline robustness — bin/deepseek(-tui).js no longer re-fetches the GitHub-hosted SHA-256 checksum manifest on every invocation. When the binary is already installed and its .version marker matches the package version, the wrapper trusts the local file. The manifest is fetched lazily on actual download (first install or DEEPSEEK_TUI_FORCE_DOWNLOAD=1), so GitHub flakes, captive portals, corporate proxies, and offline state no longer break every command.

Added

• Model-visible skills block — installed skills (name, description, file path) are now exposed in the agent's system prompt under a ## Skills section, with progressive disclosure: bodies stay on disk, the model opens a specific SKILL.md only when it decides to use that skill. Capped at a 12k prompt budget with 512-char per-description truncation. Threaded through EngineConfig.skills_dir so the TUI app, exec agent, and runtime thread manager all populate it from Config::skills_dir().
• Simplified Chinese README (README.zh-CN.md) with cross-link from the English README.

Changed

• cargo install UX — to install the canonical deepseek command, cargo install deepseek-tui-cli (the historical path). The 0.8.1 one-command flow (cargo install deepseek-tui providing both binaries) is reverted because it broke Windows release builds; install both packages separately if you want the TUI binary too.

[0.8.1] - 2026-05-01

Fixed

• One-command Cargo install — cargo install deepseek-tui --locked now provides both the canonical deepseek dispatcher and the deepseek-tui companion binary from the main deepseek-tui package, so dispatcher subcommands such as deepseek doctor --json work without installing deepseek-tui-cli separately.

0.8.0 - 2026-05-01

Fixed

• Shell FD leak / post-send lag — completed background shell jobs now release their process, stdin, stdout, and stderr handles as soon as completion is observed, while keeping the job record inspectable. This prevents long-running TUI sessions from hitting Too many open files (os error 24), which could make checkpoint saves fail and cause shell spawning, message send, close, and Esc/cancel paths to lag or fail.
• Windows REPL runtime CI startup — Windows gets a longer Python bootstrap readiness timeout for the REPL runtime tests, matching GitHub runner startup contention without weakening bootstrap failures on other platforms.

Added

• China / mirror-friendly Cargo install docs — README now documents installing through the TUNA Cargo mirror and direct release assets for users with slow GitHub/npm access.

Tests

• Added a regression test proving completed background shell jobs drop their live process handles after exec_shell_wait.
• Re-ran the focused shell cancellation and Python REPL runtime slices.

0.7.9 - 2026-05-02

Fixed

• Post-turn freeze — the checkpoint-restart cycle boundary (maybe_advance_cycle) now runs before TurnComplete emission instead of after, so the terminal is immediately responsive when the UI receives the completion event. The status chip ("↻ context refreshing…") remains visible during the cycle wait. (#234)
• Enter during streaming no longer corrupts the turn — a new QueueFollowUp submit disposition parks the draft on queued_messages when the model is actively streaming text. Previously, pressing Enter during streaming would forward the message as a mid-turn steer, which could interfere with the in-flight response. The message now dispatches as a normal user message after TurnComplete. (#234)
• Idempotent Esc during fanout — finalize_active_cell_as_interrupted and finalize_streaming_assistant_as_interrupted are now guarded by Option::take(). When Esc cancels a turn and the engine later delivers TurnComplete(Interrupted), the second call is a no-op — no double [interrupted] prefix, no corrupted cell state. Regression test locks in the contract. (#243)

Tests

• 2 new tests: submit_disposition_queue_follow_up_when_streaming (Enter/steering fix), turn_complete_after_esc_is_idempotent (Esc fanout double-call hardening)
• 1 expanded test: submit_disposition_queue_when_offline_and_busy now covers streaming state

0.7.8 - 2026-05-01

Added

• exec_shell_cancel tool — cancel a running background shell task by id, or cancel all running tasks with all: true. Requires approval. (#248)
• Foreground-to-background shell detach — press Ctrl+B while a foreground command is running to open shell controls and either detach the command to the background (where it can be polled via exec_shell_wait) or cancel the current turn. (#248)
• exec_shell_wait turn-cancellation awareness — canceling a turn while exec_shell_wait is blocking now stops the wait but leaves the background task running, with wait_canceled: true in metadata. (#248)
• ShellControlView modal (Ctrl+B) — two-option dialog (Background / Cancel) rendered as a popup over the transcript. (#248)

Changed

• exec_shell foreground path now spawns all foreground commands through the background job table, enabling the detach-to-background flow. Metadata now includes backgrounded: true/false. (#248)
• exec_shell_interact poll loop now observes the turn cancel token so stalled interactive sessions don't block turn cancellation. (#248)
• Transcript running-tool hint — executing shell cells now show "Ctrl+B opens shell controls" while running. (#248)
• Keybinding registry now includes Ctrl+B (opens shell controls) next to Ctrl+C (cancel/exits). (#248)
• Deferred swarm card creation — agent_swarm no longer pre-seeds an all-pending FanoutCard from ToolCallStarted; the card is created only when the first SwarmProgress event carries real worker state. Until then the sidebar uses the declared task count as a pending dispatch placeholder. (#236, #238)
• Swarm wording normalized — fanout-family fallback labels now render as swarm, matching the canonical agent_swarm / rlm model and avoiding mixed fanout / swarm terminology in the transcript. (#236, #238)
• OPERATIONS_RUNBOOK and TOOL_SURFACE updated with new shell control paths and exec_shell_cancel documentation.

Fixed

• Nonblocking swarm state drift — the sidebar no longer falls back to 0 or a contradictory seeded placeholder before the first progress event arrives, which removes the visible pending vs running/done mismatch during early agent_swarm dispatch. (#236, #238)
• Unicode-safe search globbing — search wildcard matching now iterates on UTF-8 char boundaries instead of raw byte offsets, preventing panics on filenames like dialogue_line__冰糖.mp3. (#249)

Tests

• 7 new integration tests: foreground-to-background detach, wait-cancel-leaves-process, single-task cancel, bulk cancel (kill-all), foreground-cancel-kills, ShellControlView default/select states
• Expanded swarm/sidebar regression coverage for deferred card creation and pending-count fallback before first SwarmProgress. (#236, #238)
• Added a Unicode filename regression test for wildcard search matching. (#249)

0.7.7 - 2026-04-30

Added

• Checklist card rendering — checklist_write / todo_* results now render as a purpose-built card with completed/total + percent header, per-item status markers (✅ / ● / ○), and a collapsing affordance for long lists. Plumbed through GenericToolCell so no new variant threading is needed. (#241)
• Context menu for transcript operations — right-click or Ctrl+M opens a context-sensitive menu with Copy, Copy All, and selection-aware actions. (crates/tui/src/tui/context_menu.rs)
• Windows .exe sibling lookup — locate_sibling_tui_binary in the CLI dispatcher finds deepseek-tui.exe on Windows, honours DEEPSEEK_TUI_BIN override, and falls back to suffix-less lookup. Tests lock in platform-correct name resolution and env override. (#247)

Changed

• Swarm/sub-agent canonical data model — SwarmTaskOutcome and SwarmOutcome are now the single source of truth. Every UI surface (sidebar, transcript FanoutCard, footer) reads from swarm_jobs rather than maintaining parallel projections. (#236, #238)
• swarm_card_index binds each swarm to its own FanoutCard by swarm_id, so overlapping fanouts no longer have one swarm's late progress clobber another's card. (#236, #238)
• Fanout-class tools suppressed from footer — agent_swarm, spawn_agents_on_csv, rlm, and agent_spawn no longer appear as active tools in the status strip; sidebar and FanoutCard show the actual worker counts. (#236, #238)
• Esc clears active tool entries optimistically — the active cell is finalized immediately on cancel rather than waiting for the engine's TurnComplete echo. Background block:false swarms remain durable and tracked through swarm_jobs. (#243)
• Post-turn workspace snapshot detached — the snapshot still runs on spawn_blocking but the engine no longer awaits its JoinHandle, so the UI accepts input immediately after TurnComplete. (#234)
• Shell output preserves Cargo/test summaries under truncation — high-signal tail lines (test result:, failures:, error[E…], Finished, Compiling, panic markers) survive truncation so the agent doesn't re-run gates. (#242)
• Monotonic spend display — displayed_session_cost + displayed_cost_high_water ensure the visible session+sub-agent total never decreases across reconciliation events (cache discounts, provisional → final). (#244)
• Clipboard module expanded with additional platform-aware copy/paste paths. (crates/tui/src/tui/clipboard.rs)
• Context inspector enriched with additional metadata columns and session-scoped agent state. (crates/tui/src/tui/context_inspector.rs)
• Configuration documentation updated for v0.7.7 settings. (docs/CONFIGURATION.md, docs/MODES.md)

Fixed

• Windows npm install path — the npm-distributed deepseek dispatcher now locates the platform-correct deepseek-tui binary (.exe suffix on Windows), fixing runtime failures for Windows users. (#247)
• Sidebar/transcript/footer agreement — all three surfaces now agree on agent counts and status because they share the canonical swarm_jobs store. (#236, #238)
• Fanout card clobbering — overlapping swarms no longer overwrite each other's progress cards. (#238)
• Cost display regression — negative reconciliation events (cache-hit discount applied after provisional count) no longer briefly drop the displayed cost. (#244)

Tests

• 65+ new/expanded tests: checklist card rendering, swarm card index binding, fanout tool suppression, Esc cancel contract, monotonic spend under reconciliation, shell summary preservation, Windows sibling binary lookup, clipboard platform paths, context menu state transitions

Added

• UI Localization registry — locale setting in settings.toml (auto, en, ja, zh-Hans, pt-BR) with LC_ALL/LC_MESSAGES/LANG auto-detection. Core packs shipped for English, Japanese, Chinese Simplified, and Brazilian Portuguese covering composer placeholder, history search, /config chrome, and help overlay. Missing/unsupported locales fall back to English. (crates/tui/src/localization.rs, docs/CONFIGURATION.md)
• Grouped, searchable /config editor — settings organized by section (Model, Permissions, Display, Composer, Sidebar, History, MCP) with live substring filter. Typing j/k navigates when the filter is empty; otherwise they enter the filter. (crates/tui/src/tui/views/mod.rs)
• Pending input preview widget — while a turn is running, queued messages, pending steers, rejected steers, and context chips render above the composer. Three-row-per-message truncation with ellipsis overflow. (crates/tui/src/tui/widgets/pending_input_preview.rs)
• Alt+↑ edit-last-queued — pops the most recently queued message back into the composer for editing. No-op when the composer is dirty. (crates/tui/src/tui/app.rs)
• Composer history search and draft recovery — Alt+R opens a live substring search across input_history and draft_history (max 50 entries). Enter accepts, Esc restores the pre-search draft. Unicode case-insensitive matching. (crates/tui/src/tui/app.rs)
• Paste-burst detection — fallback rapid-key paste detection independent of terminal bracketed-paste mode. Configurable via paste_burst_detection setting (default on). CRLF normalization (\r\n → \n, \r → \n). (crates/tui/src/tui/paste_burst.rs)
• Composer attachment management — ↑ at the composer start selects the attachment row; Backspace/Delete removes it without editing placeholder text. (crates/tui/src/tui/app.rs)
• Searchable help overlay — live substring filter across slash commands and keybindings, multi-term AND matching, localized chrome. (crates/tui/src/tui/views/help.rs)
• Keyboard-binding documentation catalog — single source of truth for help overlay rendering. Documents 38+ keyboard chords across Navigation, Editing, Submission, Modes, Sessions, Clipboard, and Help sections. (crates/tui/src/tui/keybindings.rs)
• Legacy Rust deprecation audit — non-destructive compatibility audit covering legacy MCP sync API, prompt constants, /compact, todo_* aliases, sub-agent aliases, provider api_key compatibility, model alias canonicalization, and palette aliases. Tracked by #218–#221. (docs/LEGACY_RUST_AUDIT_0_7_6.md)

Changed

• Shift+Tab cycles reasoning-effort through Off → High → Max (three behaviorally distinct tiers). Previously Tab cycled modes; Shift+Tab is now the reasoning-effort shortcut. (crates/tui/src/tui/app.rs:1119)
• Reasoning-effort Off now sends "off" to the API (was None). Allows explicit thinking disable. (crates/tui/src/tui/app.rs)
• Media @-mentions now emit <media-file> hints directing users to /attach instead of inlining binary bytes. Tests lock in the contract. (crates/tui/src/tui/file_mention.rs)
• /attach rejects non-media files with a descriptive error pointing to @path for text. (crates/tui/src/commands/attachment.rs)
• Configuration reference updated to cover all v0.7.6 settings: locale, paste_burst_detection, reasoning_effort, composer_density, sidebar_focus, and more. (docs/CONFIGURATION.md)

Fixed

• Unicode-safe truncation in pending-input preview and view text — no more mid-character breaks on multi-byte UTF-8. (crates/tui/src/tui/widgets/pending_input_preview.rs, crates/tui/src/tui/views/mod.rs)
• CJK/emoji display-width handling in locale tests and config view rendering. (crates/tui/src/localization.rs)
• Context preview distinguishes @media, /attach, missing, and included files with separate kind labels and inclusion status. (crates/tui/src/tui/file_mention.rs)
• Config view filter accept j/k only when filter is empty — typing j or k into the filter field no longer navigates away. (crates/tui/src/tui/views/mod.rs)

Tests

• 7 localization tests (tag normalization, env resolution, shipped pack completeness, missing-key fallback, Unicode width truncation)
• 11 pending-input preview tests (context buckets, truncation, URL overflow, narrow-width)
• 13 paste tests (burst detection, CRLF normalization, clipboard images, Unicode)
• 9 draft/history search tests (match filter, unicode, accept/cancel, recovery)
• 93 config tests (grouping, filter, edit, j/k, localization, escape/cancel)
• 24 workspace tests (context refresh, scroll, mention completion)
• 7 file-mention tests (context references, media/attach distinction, removability)

[0.7.1] - 2026-04-28

Added

• Grouped active tool-call cards with compact rails and a live working-status row while tools run. (#142, #149)
• Selected-card-aware Alt+V details so the visible or selected tool card opens the matching detail payload. (#143)
• Compact terminal-native session context inspector with persisted @path and /attach reference metadata for resumed transcripts. (#146, #150)

Changed

• Polished tool cards, diff summaries, and pending context previews for denser terminal-native scanning. (#141, #144, #145, #148)
• Ranked Ctrl+P file-picker results with working-set relevance from modified files, recent @file mentions, and recent tool paths while keeping fuzzy filtering in memory. (#147)

[0.7.0] - 2026-04-28

Added

• OS keyring-backed auth storage with deepseek auth subcommands, migration from plaintext config, provider-aware key resolution, and doctor visibility. (#134)
• Egress network policy with allow/deny/prompt decisions, deny-wins matching, audit logging, and enforcement hooks for network-capable tools. (#135)
• LSP diagnostics auto-injection after edits so compile feedback can be reinjected into the next agent turn. (#136)
• Side-git workspace snapshots, /restore, and revert_turn so agent edits can be rolled back without moving the user's repository HEAD. (#137)
• Esc-Esc backtrack over prior user turns, desktop turn-complete notifications, Alt+V tool-details access, safer command-prefix auto-allow matching, bundled skill-creator, and /skill install management for community skills. (#131, #132, #133, #138, #139, #140)

Changed

• Split more engine/tool primitives into focused modules and workspace crates, including shared tool result primitives and extracted turn/capacity flow. (#67, #74)

Tests

• Added mock LLM and skill-install integration coverage for streaming turns, reasoning replay, tool-call loops, network policy, and skill validation. (#69, #140)

[0.6.5] - 2026-04-27

Added

• rlm_process tool — recursive language model as a tool call. The previous /rlm slash command had a UI rendering gap (the answer never made it back to the model's view) and required the user to remember to invoke it manually. rlm_process exposes the full RLM loop as a structured tool the model itself can choose, the same way it reaches for agent_spawn or rlm_query. Inputs: task (small instruction, shown to the root LLM each iteration) plus exactly one of file_path (workspace-relative, preferred — keeps the long input out of the model's context entirely) or content (inline, capped at 200k chars). Optional child_model (default deepseek-v4-flash) and max_depth (default 1, paper experiments). Returns the synthesized answer with metadata (iterations, duration, tokens, termination reason). Loaded across Plan / Agent / YOLO; never deferred via ToolSearch. (crates/tui/src/tools/rlm_process.rs)
• Reference-aligned REPL surface. Aligned the in-REPL Python helpers with the canonical reference RLM (alexzhang13/rlm). The sub-agent now sees context (the full input, not PROMPT), llm_query, llm_query_batched, rlm_query (was sub_rlm), rlm_query_batched, SHOW_VARS(), FINAL(...), FINAL_VAR(...), plus repl_get/repl_set. Same prompt patterns and decomposition strategies from the paper now apply verbatim. (crates/tui/src/repl/runtime.rs)
• Concurrent fanout from inside the REPL. llm_query_batched(prompts, model=None) runs up to 16 child completions in parallel via a new POST /llm_batch sidecar endpoint — much faster than serial [llm_query(p) for p in prompts]. rlm_query_batched(prompts) does the same for recursive RLM sub-calls via POST /rlm_batch. (crates/tui/src/rlm/sidecar.rs)
• SHOW_VARS() — returns {name: type-name} for every user variable in the REPL. Lets the model inspect what it has accumulated across rounds before deciding whether to call FINAL_VAR(name).
• Auto-persistence of REPL variables across rounds. Any top-level JSON-serializable variable the sub-agent creates in a repl block now persists to the next round automatically — no repl_set ceremony needed unless you want explicit control. Matches the in-process reference REPL semantics.

Changed

• Code fence is repl, not python. Matches the reference RLM language identifier so the same prompts and few-shot examples work here. Backward-compat fallback to python / py retained for older model behaviors.
• FINAL / FINAL_VAR parseable from raw response text. The reference RLM lets the model write FINAL(value) on its own line outside any code block to terminate the loop. Added parse_text_final() so that path works alongside the existing in-REPL Python sentinel mechanism. Code-fenced occurrences of FINAL(...) are correctly ignored to avoid false positives.
• Strict termination loop. The sub-agent must emit a ```repl block (or text-level FINAL) to make progress. One fence-less round triggers a reminder; two consecutive trigger a RlmTermination::DirectAnswer exit so we don't loop forever.
• rlm_process separates task (root_prompt) from file_path/content (context). The task rides along as root_prompt and is shown to the root LLM each iteration; the big input lives only in the REPL as context. Mirrors the reference's completion(prompt, root_prompt=...) API.
• System prompt rewritten with the reference's strategy patterns (PREVIEW → CHUNK + map-reduce via llm_query_batched → RECURSIVE decomposition via rlm_query → programmatic computation + LLM interpretation).
• The /rlm slash command stays for manual experimentation but is no longer the recommended path; the description in commands/mod.rs now points the model toward rlm_process for the in-agent flow.

Reference

• Zhang, Kraska, Khattab. "Recursive Language Models." arXiv:2512.24601.
• alexzhang13/rlm — reference implementation by the paper authors. Variable names, helper surface, and code-fence convention align with that repo so prompts and patterns transfer.

Fixed

• /rlm actually recurses now (Algorithm 1 substrate, paper-faithful). The v0.6.3 RLM loop had the right shape but its recursive substrate was non-functional: llm_query() was a Python stub that returned a hardcoded string, and child_model was bound with an underscore prefix and silently dropped. The loop ran but the sub-LLM never fired. v0.6.4 fixes this end-to-end:
  • HTTP sidecar. Each RLM turn spins up a localhost-only axum server on a kernel-assigned port for the duration of the turn. Python's llm_query() and sub_rlm() are real urllib.request.urlopen POSTs; Rust services them via the existing DeepSeek client and returns the completion text. No long-lived python process, no FIFOs, no two-pass replay — Python blocks on HTTP, Rust answers it. (crates/tui/src/rlm/sidecar.rs)
  • child_model is plumbed through. Op::RlmQuery and AppAction::RlmQuery carry the configured child model (default deepseek-v4-flash) all the way to the sidecar, where every llm_query() call uses it. Token usage is folded into RlmTurnResult.usage so cost tracking works.
  • sub_rlm() is exposed as a paper-faithful recursive RLM call. The Python REPL gets a real sub_rlm(prompt) function that runs another full Algorithm-1 turn at depth-1 inside the same process (different sidecar route, decremented recursion budget). Default max_depth = 2 from the /rlm command — the model can recurse twice before the budget hits zero. The recursive opaque-future cycle (run_rlm_turn_inner → start_sidecar → sub_rlm_handler → run_rlm_turn_inner) is broken by returning a concrete Pin<Box<dyn Future + Send>> from run_rlm_turn_inner.
  • Strict termination. The loop only ends via FINAL(value) (or the iteration cap). The previous "no fence = direct answer, end loop" early-exit deviated from the paper and could short-circuit on iteration 1 with a chatty model that never saw PROMPT. The new behavior tolerates one fence-less round (with a reminder appended), then falls back to a RlmTermination::DirectAnswer exit. RlmTurnResult now carries a termination: RlmTermination enum (Final | DirectAnswer | Exhausted | Error) so callers can tell what happened.
  • Richer Metadata(state). The metadata message the root LLM sees now includes paper-required access patterns (repl_get, slicing, splitlines, repl_set, llm_query, sub_rlm, FINAL) and a live list of variable keys currently in the REPL state file — so the model can see what it's accumulated across rounds without us shipping the values themselves.
  • Unicode-safe truncation. truncate_text now counts Unicode codepoints (was mixing text.len() bytes with chars().take(n)), so multi-byte previews can no longer mis-count. Per-turn temp state files are cleaned up on completion. ROOM_TEMPERATURE typo → ROOT_TEMPERATURE.
  • End-to-end smoke test. rlm::turn::tests::sidecar_url_is_exported_to_python_env stands up a stand-in axum server that always replies {"text":"pong-from-sidecar"}, runs print(llm_query('hello')) in the real PythonRuntime, and asserts the reply round-trips. This catches future regressions in the sidecar URL passthrough.

Reference

• Zhang, Kraska, Khattab. "Recursive Language Models." arXiv:2512.24601 (Algorithm 1).

Added

• Sub-agents surface in the footer status strip. When N > 0 sub-agents are in flight, the footer grows a "1 agent" / "N agents" chip in DeepSeek-sky color matching the model badge. Hides entirely at zero. (footer_agents_chip in widgets/footer.rs)
• @-mention popup is fully wired in the composer. Previously only the App state fields existed (mention_menu_selected, mention_menu_hidden). The popup now renders below the input mirror-style with the slash menu, with @-prefixed entries; Up/Down navigates, Enter / Tab apply the selection, Esc hides until the next input edit. Mention takes precedence over slash because the positional check is stricter. (visible_mention_menu_entries + apply_mention_menu_selection in file_mention.rs)

Fixed

• Tool-call cells no longer flash <command> / <file> placeholders. The engine used to emit ToolCallStarted from ContentBlockStart with input: {} — before any InputJsonDelta had streamed in — which baked the placeholder into the cell at creation time. The emission is now deferred to ContentBlockStop and routed through final_tool_input, so the cell is created with the parsed args already in hand. (engine.rs final_tool_input; engine/tests.rs final_tool_input_*)
• parse_invocation_count flake. Two markdown_render tests both read the global PARSE_INVOCATIONS atomic and raced when other tests called parse() in parallel. Switched the counter to thread_local!<Cell<u64>>, so each test thread sees only its own invocations. Tested 8 sequential full-suite runs: 8/8 green (was ~40% green).

Changed

• System prompts redesigned with decomposition-first philosophy. All four prompt tiers (base, agent, plan, yolo) now teach the model to decompose tasks before acting — todo_write first for granular task tracking, update_plan for high-level strategy, and sub-agents for parallelizable work. Inspired by the "mismanaged geniuses hypothesis" (Zhang et al., 2026): frontier LMs are already capable enough; the bottleneck is how we scaffold their self-management. The prompts now make work visible through the sidebar (Plan / Todos / Tasks / Agents) instead of letting the model work invisibly.
• Tool labels use progressive verbs. "Read foo.rs" → "Reading foo.rs", "List X" → "Listing X", "Search pattern" → "Searching for pattern", "List files" → "Listing files". Past-tense labels read wrong while a tool is still in flight; the new forms match what the user actually sees.
• Long-running tools grow an elapsed badge. From 3 s onward the running status segment becomes running (3s), running (4s), … so the user can tell a tool isn't stuck. The status-animation tick (360 ms) drives the redraw; below 3 s the badge stays hidden so quick reads/greps don't churn. (history.rs running_status_label_with_elapsed)
• Spinner pulse is twice as fast — TOOL_STATUS_SYMBOL_MS 1800 ms → 720 ms per glyph (full 4-glyph heartbeat in ~2.88 s instead of ~7.2 s).
• tools/subagent.rs is now a folder module. Tests live in tools/subagent/tests.rs; runtime + manager + tool implementations stay in tools/subagent/mod.rs. Public API unchanged. The runtime / tool-impl split was deferred — SubAgentTask, run_subagent_task, build_allowed_tools, the agent prompt constants, and normalize_role_alias are referenced from both layers and need a small API design pass before they cleanly separate.

Test hygiene

• 5 regression tests pin auto-scroll churn contract. mark_history_updated does not scroll; tool-cell handlers only mark_history_updated; add_message and flush_active_cell gate on user_scrolled_during_stream; the per-stream lock clears at TurnComplete and when the user returns to the live tail. (P2.4)

0.6.1 - 2026-04-26

Changed

• V4 cache-hit input prices cut to 1/10th per DeepSeek's pricing update. Pro promo 0.03625→0.003625, Pro base 0.145→0.0145, Flash 0.028→0.0028 per 1M tokens. Cache-miss and output rates unchanged.
• Removed the "light" theme option. It was never tested, looked bad, and the dark/whale palettes are the supported targets. Theme validation now accepts only default, dark, and whale.
• System prompts redesigned with decomposition-first philosophy. All five prompt tiers teach the model to todo_write before acting, update_plan for strategy, and sub-agents for parallel work. Inspired by the mismanaged-geniuses hypothesis (Zhang et al., 2026).

0.6.0 - 2026-04-25

Added

• rlm_query tool — recursive language models as a first-class structured tool. Inspired by Alex Zhang's RLM work and Sakana AI's published novelty-search research, but trimmed to what an agent loop actually needs. The model calls rlm_query with one prompt or up to 16 concurrent prompts; children run on deepseek-v4-flash by default and can be promoted to Pro per-call. Children dispatch concurrently via tokio::join_all against the existing DeepSeek client — no external runtime, no fenced-block DSL, no Python sandbox. Returns plain text for one prompt, indexed [0] ...\n\n---\n\n[1] ... blocks for many. Available in Plan / Agent / YOLO. Cost is folded into the session's running total automatically.

Changed

• Scroll position survives content rewrites (#56). TranscriptScroll::resolve_top and scrolled_by no longer teleport to bottom when the anchor cell vanishes. Three-level fallback chain: same line → same cell, line 0 → nearest surviving cell at-or-before. Previously, any rewrite of the assistant message (e.g. tool-result replacement) silently dropped the user back to the live tail mid-scroll.
• Looser command-safety chains (#57). cargo build && cargo test, git fetch && git rebase, and similar chains of known-safe commands now escalate to RequiresApproval instead of being hard-blocked as Dangerous. Chains containing unknown commands still block.
• GettingCrowded no longer surfaces a footer chip. The context-percent header already covers conversation pressure; the chip now only fires for active engine interventions (refreshing context, verifying, resetting plan).

[0.5.2] - 2026-04-25

Added

• /model opens a Pro/Flash + thinking-effort picker (#39). Typing /model with no argument now pops a two-pane modal: model on the left (deepseek-v4-pro flagship, deepseek-v4-flash fast/cheap, plus a "current (custom)" row when the active id isn't one of the listed defaults), and thinking effort on the right. Tab/←/→ swaps panes, ↑/↓ moves within the focused pane, Enter applies both selections, Esc cancels. The effort pane intentionally exposes only Off / High / Max because DeepSeek's Thinking Mode docs state low/medium are mapped to high server-side and xhigh is mapped to max — the legacy variants stay valid in ~/.deepseek/settings.toml for back-compat, the picker just doesn't surface them. Apply path persists default_model and reasoning_effort to settings, forwards Op::SetModel + Op::SetCompaction to the running engine so the next turn picks up the change without a restart, and resets the per-turn token gauges (cache, replay) so the footer numbers reflect the new model. /model <id> keeps working unchanged for power users.

[0.5.1] - 2026-04-25

Added

• fetch_url tool for direct HTTP GET on a known URL — complements web_search for cases where the link is already known. Supports format (markdown / text / raw), max_bytes (default 1 MB, hard cap 10 MB), timeout_ms (default 15 s, max 60 s), redirect following, and structured {url, status, content_type, content, truncated} responses. 4xx/5xx bodies are returned (with success: false) so the caller can read JSON error envelopes. (#33)
• PDF support in read_file. PDFs are auto-detected by extension or %PDF- magic bytes and extracted via pdftotext -layout (poppler) when available. New optional pages arg ("5" or "1-10") reads page slices. Without pdftotext, returns a structured {type: "binary_unavailable", kind: "pdf", reason, hint} with install commands for macOS/Debian. (#34)
• Reasoning-content replay telemetry, end-to-end (#30). The chat-completions sanitizer now estimates replayed reasoning_content tokens (~4 chars/token), threads the value through the streaming Usage payload, stores it on the App, and renders an rsn N.Nk chip in the footer next to the cache hit-rate. The chip turns warning-coloured when replay tokens exceed 50% of the input budget, so users on long thinking-mode loops can see at a glance how much of their context window is going to V4's "Interleaved Thinking" replay (paper §5.1.1). Logged at RUST_LOG=deepseek_tui=info for tail-friendly diagnosis.
• @file Tab-completion (#28). Typing @<partial> and pressing Tab now resolves the mention against the workspace using the existing ignore::WalkBuilder. A unique match is spliced into the input; multiple matches with a longer common prefix extend the partial; remaining ambiguity is surfaced via the status line. The mention-expansion path that ships file contents to the model is unchanged — this is purely a discovery aid for typing the path. Inline-contents and a fuzzy popup picker are queued for v0.5.2.
• Per-workspace external trust list (#29). ~/.deepseek/workspace-trust.json now records, for each workspace, the absolute paths the user has opted into reading/writing from outside that workspace. The new /trust slash command supports add <path>, remove <path>, list, on, off, and a status read with no args; the engine consults the list when constructing every ToolContext so changes apply on the next tool call without restart. /diagnostics surfaces the list. The interactive "Allow once / Always allow / Deny" approval prompt is deferred — for now grant access ahead of the turn with /trust add <path>.

Fixed

• TUI sidebar gutter bleed regression test (#36). Snapshot tests now lock in that long single-line tool results — including a todo_write echo of a multi-kilobyte JSON payload — never write any cells outside chat_area at the widths reported in the bug (80, 120, 165, 200 cols). A second test verifies the scrollbar coexists with content along the right edge instead of overdrawing the penultimate column.
• Version drift caught in CI. New versions job in .github/workflows/ci.yml runs scripts/release/check-versions.sh on every push/PR, verifying every per-crate Cargo.toml inherits the workspace version, the npm wrapper matches the workspace version, and Cargo.lock is in sync. The release runbook now lists check-versions.sh as the first preflight step. (#31)
• Per-mode soft context budget for V4 compaction trigger (#27).
• Phantom web.run references stripped from prompts and the web_search tool surface (#25).
• Unused import + cargo fmt drift that landed with feat(#27) and broke Build / Test / npm wrapper smoke under -Dwarnings.

[0.5.0] - 2026-04-25

Fixed

• Multi-turn tool calls on thinking-mode models no longer return HTTP 400. Every assistant message in the conversation now carries reasoning_content when thinking is enabled — not just tool-call rounds — matching DeepSeek's actual API validation, which rejects any assistant message missing the field even though the docs describe non-tool-call reasoning as "ignored".
• Added a final-pass wire-payload sanitizer in the chat-completions client that forces a non-empty reasoning_content placeholder onto any assistant message still missing one at request time. This is the last line of defense after engine-side and build-side substitution, so sessions restored from older checkpoints, sub-agents that append messages directly, and cached prefix mismatches all produce a valid request.
• On a reasoning_content-related 400, the client now logs the offending message indices to make future regressions diagnosable.
• Stripped phantom web.run references from prompts and the web_search tool surface (#25).

Changed

• Header/UI widget refactor in the TUI (crates/tui/src/tui/ui.rs, widgets/header.rs) — internal cleanup, no user-visible behavior change.

0.4.9 - 2026-04-27

Fixed

• DeepSeek thinking-mode tool-call rounds now always replay reasoning_content in all subsequent requests (including across new user turns), matching DeepSeek's documented API contract that assistant messages with tool calls must retain their reasoning content forever.
• Missing reasoning_content on a tool-call assistant message now substitutes a safe placeholder ("(reasoning omitted)") instead of dropping the tool calls and their matching tool results, preventing orphaned conversation chains and API 400 errors.
• Session checkpoint now persists a Thinking-block placeholder for tool-call turns that produced no streamed reasoning text, keeping on-disk sessions structurally correct so subsequent requests avoid HTTP 400 rejections.
• Token estimation for compaction now counts thinking tokens across all tool-call rounds (not just the current user turn), aligning with the updated reasoning_content replay rule.

0.4.8 - 2026-04-25

Fixed

• DeepSeek V4 Pro cost estimates now use DeepSeek's current limited-time 75% discount until 2026-05-05 15:59 UTC, then automatically fall back to the base Pro rates.

[0.4.5] - 2026-04-24

Fixed

• Alternate-screen TUI sessions now capture mouse input by default so wheel scrolling moves the transcript instead of exposing terminal scrollback from before the TUI started. Use --no-mouse-capture or tui.mouse_capture = false when terminal-native drag selection is preferred.

[0.4.2] - 2026-04-24

Fixed

• DeepSeek V4 thinking-mode tool turns now checkpoint the engine's authoritative API transcript, including assistant reasoning_content on reasoning-to-tool-call turns with no visible assistant text.
• Chat Completions request building now drops stale V4 tool-call rounds that are missing required reasoning_content, preventing old corrupted checkpoints from triggering DeepSeek HTTP 400 replay errors.
• Web search now falls back to Bing HTML results when DuckDuckGo returns a bot challenge or otherwise yields no parseable results.

[0.4.1] - 2026-04-24

Fixed

• DeepSeek V4 tool-result context now preserves large file reads and command outputs instead of compacting noisy tools to a 900-character snippet after 2k characters.
• Capacity guardrail refresh no longer performs destructive summary compaction unless the normal model-aware compaction thresholds are actually crossed.
• V4 compaction summaries retain larger tool-result excerpts and summary input when compaction is genuinely needed.
• The transcript now follows the bottom again when sending a new message, shows an in-app scrollbar when internally scrolled, and leaves mouse capture off in --no-alt-screen mode so terminal-native scrolling can work.

[0.4.0] - 2026-04-23

Added

• DeepSeek V4 support: deepseek-v4-pro (flagship) and deepseek-v4-flash (fast/cheap) are now first-class model IDs with 1M context windows.
• Reasoning-effort tier: new reasoning_effort config field (off | low | medium | high | max) mapped to DeepSeek's reasoning_effort + thinking request fields. Defaults to max.
• Shift+Tab cycles reasoning-effort through the three behaviorally distinct tiers (off → high → max). The current tier is shown as a ⚡ chip in the header.
• Per-model pricing table: deepseek-v4-pro priced at $0.145/$1.74/$3.48 per 1M tokens (cache-hit/miss/output); deepseek-v4-flash and legacy aliases at $0.028/$0.14/$0.28.

Changed

• Default model flipped to deepseek-v4-pro (from deepseek-reasoner).
• deepseek-chat / deepseek-reasoner remain as silent aliases of deepseek-v4-flash for API compatibility; priced identically.
• Context compaction: 1M-context V4 models now compact at 800k input tokens or 2,000 messages, so short/tool-heavy sessions do not compact as if they were 128k-context runs.
• Cycling modes is now Tab-only; Shift+Tab is repurposed for reasoning-effort (reverse-mode cycle was low-value with only three modes).
• Updated help/hint strings, validator error messages, and the model picker to reference V4 IDs.

Fixed

• requires_reasoning_content now recognizes deepseek-v4* so thinking streams render correctly on V4 models.
• DeepSeek V4 thinking-mode tool calls now preserve prior assistant reasoning_content whenever a tool call is replayed, matching DeepSeek's multi-turn contract and avoiding HTTP 400 rejections on later turns.
• Raw Chat Completions requests now send DeepSeek's top-level thinking parameter instead of the OpenAI SDK-only extra_body wrapper.
• Config, env, and UI model selection now normalize legacy DeepSeek aliases to deepseek-v4-flash instead of preserving old model labels.
• npm wrapper first-run downloads now use process-unique temp files so concurrent deepseek / deepseek-tui invocations do not race on *.download files.

0.3.33 - 2026-04-11

Changed

• Footer polish: simplified footer rendering, removed footer clock label, updated status line layout
• Palette cleanup: removed FOOTER_HINT color constant

Removed

• FOOTER_HINT color constant from palette (use TEXT_MUTED or TEXT_HINT instead)

Fixed

• Test updates to align with simplified footer logic
• Empty state placeholder text removed for cleaner UI

0.3.32 - 2026-04-11

Added

• Finance tool: Yahoo Finance v8 quote endpoint with chart fallback, supporting stocks, ETFs, indices, forex, and crypto lookups.
• Header widget redesign: proportional truncation, context-usage bar with gradient fill, streaming indicator, and graceful narrow-terminal degradation.
• Expanded test coverage: 680+ tests including footer state, context spans, plan prompt lifecycle, workspace context refresh, header rendering, and finance tool integration tests with wiremock.
• Workspace context refresh with configurable TTL and deferred initial fetch.
• Config command additions for runtime settings management.

Changed

• Redesigned footer status strip with mode/model/status layout, context bar, and narrow-terminal fallback.
• Plan prompt now uses numeric selection (1-4) instead of keyword input; old aliases are sent as regular messages.
• Archived outdated docs (workspace_migration_status.md -> docs/archive/).
• Trimmed AGENTS.md boilerplate and updated task counts.
• Clarified release-surface documentation: crates.io publication may lag the workspace/npm wrapper.

Fixed

• Header metadata_spans now uses saturating_sub to prevent underflow on narrow terminals.
• Finance tool reuses a single HTTP client instead of rebuilding per request.
• Finance tool tests no longer leak temp directories.

0.3.31 - 2026-03-08

Added

• Replaced the finance tool backend with Yahoo Finance v8 + CoinGecko fallback for reliable real-time market data (stocks, ETFs, indices, forex, crypto).
• Added compaction UX: status strip shows animated COMPACTING indicator during context summarization, footer reflects compaction state, and CompactionCompleted events now include message count statistics.
• Added send flash: brief tinted background highlight on the last user message after sending.
• Added braille typing indicator with smooth 10-frame animation cycle.

Changed

[0.3.30] - 2026-03-06

Added

• Added a release-ready local npm smoke path that builds binaries, serves release assets locally, packs the wrapper, installs the tarball, and checks both entrypoints before publish.
• Added an opt-in full-matrix local release-asset fixture so npm run release:check can be exercised before GitHub release assets exist.

Changed

• Bumped the Rust workspace crates and npm wrapper to 0.3.30.
• Pointed the npm wrapper's default deepseekBinaryVersion at 0.3.30 for the next coordinated Rust + npm release.
