New

More new models: added GPT-5.6 (sol / terra / Luna series) and Sonnet 5.
A refreshed look: windows on macOS now have a more refined glass background.
Fuller PDF support: attachment images can now be opened full-size; Finch extracts text directly from PDFs, and page-by-page reading is faster.
The mini tools system: mini tools are Finch's extension system, giving developers client-side capabilities via Finch's API and mini-tool developer guide.
A revamped toolbox: a combined community for mini tools and skills — add and update mini tools, or install any of them straight from the community.
Official mini tools: a Git branch tool, a Plan tool (lets the AI think before acting), and a PJBlog tool.

Improvements

Unified interaction and styling across SpaceMenu, ModelMenu, PermissionMenu, and other selector components.
Streamed Markdown tables now auto-fill missing separator rows to avoid rendering glitches.
Sidebar UI state (current tab, expanded groups, etc.) now persists consistently across restarts and multiple windows.
Code blocks now collapse based on line count, rendering only the first 36 lines when collapsed, for smoother loading of long blocks.
PDF content cache now auto-expires after 20 minutes to reduce memory use.
Added skeleton screens on the home screen and session list while loading, reducing content jumps.

Fixed the @ mention list failing to reopen after being closed with Esc.
Fixed the Edit tool losing its read record across conversation turns.
Fixed some sessions failing to restore due to invalid data in history.
Fixed thinking content bleeding into the main reply for models like kimi-code.
Fixed the Enter key mistakenly triggering shortcuts while using a Chinese IME.
Fixed leading/trailing whitespace not being trimmed when saving an API key or base URL.
Fixed conversations freezing when hitting a quota limit; Finch no longer auto-reconnects on rate limits, insufficient balance, or upstream overload, avoiding wasted quota.
Fixed sidebar UI state occasionally being lost after a restart.
Fixed the floating left sidebar covering content or showing incorrect stacking in some cases.
Fixed missing separator rows breaking multi-column Markdown tables during streaming.
Fixed duplicate user messages appearing in the timeline and gradient overlap in collapsed state.
Fixed left sidebar width memory and expand animation in compact windows.
Fixed a Windows build failure caused by a PermissionMode type mismatch in automation tasks.
Fixed some shortcut dialog copy that wasn't localized.
Fixed table display and shadow misalignment caused by a fixed table width.
Fixed Canvas window adaptation across multi-monitor setups.
Linux: fixed borderless window corner radius, borders, window control icons, and visual details on the welcome and settings screens.
