[0.8.39] - 2026-05-17

Fixed

• Feishu/Lark bridge startup order is guarded. The bridge now keeps
  ThreadStore initialized before startup opens persisted thread state, with a
  regression test to prevent moving it below its first use.
• /model picker opens instantly with the curated list again. Reverted
  the v0.8.38 live-catalog rework: the picker no longer makes a blocking
  network call on open and once again shows the curated auto /
  deepseek-v4-pro / deepseek-v4-flash rows. The /models command still
  lists the live provider catalog.
• "Approve for session" groups by command family again. Session approvals
  are keyed by a lossy, arity-aware fingerprint once more, so approving
  cargo build also covers cargo build --release. Denials keep the exact
  per-call fingerprint from Bug in deny tool use #1617, so denying one call no longer over-blocks
  later, different calls to the same tool.
• Docker first-run state directories are writable. The image now
  pre-creates /home/deepseek/.deepseek with deepseek ownership so the
  documented named-volume launch can create runtime thread state on first use
  (Docker: Permission denied (os error 13) creating .deepseek/tasks/runtime/threads on first run #1684).
• Runtime API system prompt overrides survive the first turn. Threads
  created with a system_prompt override now keep that prompt through
  mode/context refreshes before the model request is built (Runtime API: system_prompt on POST /v1/threads is accepted and stored but discarded before the model request #1688).
• Compaction keeps a user text query in tool-heavy histories. Automatic
  compaction now pins the latest user text message when the retained tail only
  contains tool calls/results, avoiding OpenAI-compatible Jinja template
  failures on the next request (fix(compaction): preserve usr txt query to prevent Jinja template crash #1704).
• Pager jumps land at the visible bottom. Pressing G or End in the pager
  no longer overshoots the render clamp, so k/Up scrolls upward immediately
  afterward, and mouse wheels now scroll pager overlays directly (fix(pager): G/End overshoot makes k/Up unresponsive after jump to bottom #1706,
  fix(tui): add mouse scroll support to pager overlay #1716).
• Mouse-wheel-as-arrow scrolling preserves composer drafts. When
  composer_arrows_scroll is enabled, Up/Down now scroll the transcript even
  with text in the composer instead of replacing the draft with input history
  (输入框有文字的情况下滚动鼠标滚轮无法上翻历史对话，只能切换输入历史 #1677).
• Multiline composer arrows move between input lines. Plain Up/Down now
  move the cursor within multiline drafts before falling back to input history,
  while single-line mouse-wheel-as-arrow scrolling remains unchanged (Multiline composer: Up/Down should navigate within input text, not jump to history #1721).
• Third-party reasoning_content streams no longer corrupt text output.
  Generic OpenAI-compatible providers that stream answer text in
  reasoning_content now render it as normal text unless the selected provider
  is one whose reasoning-content semantics are supported (reasoning_content 字段导致第三方中转 OpenAI格式 兼容 API 显示严重错乱 #1673).
• macOS system theme detection recognizes Light mode. When COLORFGBG is
  missing or unusable, theme = "system" now falls back to macOS appearance
  detection and treats a missing AppleInterfaceStyle key as Light mode
  (theme = "system" detects dark on macOS Light mode with Ghostty #1670).
• rlm_open accepts schema-filled blank source fields. Empty file_path,
  content, and url strings now count as absent, so calls that provide one
  real source no longer fail the exactly-one-source validator (bug(rlm_open): tool schema requires content/file_path/url simultaneously, causing "provide exactly one" validation f ailure #1712).
• Resize keeps transcript paging usable immediately. After a terminal
  resize, PageUp/PageDown now use the resized viewport height instead of
  falling back to one-line jumps before the next render (fix: preserve scroll position across terminal resize #1724).
• ACP responses stringify JSON-RPC ids. serve --acp now returns string
  ids even when clients send numeric ids, matching Zed's stricter ACP client
  expectations (ACP server JSON-RPC id field type mismatch with Zed editor #1696).
