1.6.3 Changelog

New

Mini programs & extensions

• Appearance capability: mini programs gain ctx.appearance, which can set the theme, custom skins, font size, font family, and Home background once permissions.appearance is granted; the permission card and its trilingual copy are rounded out alongside it.

Models & providers

• Remote provider catalog snapshot: fetching a remote provider catalog snapshot is now supported, making model catalog state more reliable.

Improvements

• Model menu cleanup: groups models by source, unifies source-card corner radii, pinned-model hints, and empty-state layout, and adds diagnostics for where a model switch originated.
• Sidebar and theme details: the sidebar menu switches to a hamburger icon, timestamps and captions are tightened, and the light-theme active row and loading animations are refined.
• Emoji coverage: adds 142 commonly used local Twemoji assets covering animals, food, nature, sporting goods, and more.
• Log maintenance: expires old logs by date, caps individual file size, and shortens the detailed log retention window to seven days.

Fixes

Sessions & compression

• Fixes streamed content rolling back, trailing flicker, stale compression boundaries, and lost follow-up suggestions when switching sessions.
• Fixes compression boundaries disappearing after collapsing a round, stale operations clearing compression state, and queued messages appearing early during a compression rerun.
• Fixes send-then-navigate timing on Home and a stale open-identity cache when reopening the latest session after creating one in a container.
• Fixes incorrect attachment restoration on the first image-and-text message, duplicated action suggestions in an error state, and missing retry details in run status.
• Fixes a theme flash when creating a session and Space session list expansion state not being written to the database.

Models & Finch Plan

• Fixes Finch Plan model catalog refresh failures, accidental automatic switching during a refresh, delayed subscription status updates, and network fluctuations signing the user out.
• Fixes new sessions not restoring the last model, defaults not updating after a model switch, broken cross-provider switching when a model becomes unavailable, and invalid drop targets when dragging models.
• Fixes usage quota ordering, duplicated Finch Plan quota card titles, and log usage not updating continuously.
• Fixes an incorrect terminal state being overwritten after a cloud model interruption.

Mini programs, rendering & platform

• Fixes concurrent mini program update states overwriting each other and permission warnings displaying incorrectly.
• Fixes relative file links being rendered as blocked and local images failing to display on Windows.
• Fixes text-default emoji such as ✌️ not rendering correctly as Twemoji.

Appearance

• Corrects the custom skin --text-inverse derivation: instead of inverting RGB directly, it now blends white or black according to the theme base, preventing saturated dark colors from looking washed out or gray on accent backgrounds.

1.6.2 Changelog

New

Sessions & interaction

• Full-window session header: overview, mini program panel, and session menu move into the title bar.
• Session breadcrumbs: the top level is a scope dropdown that jumps straight to a new conversation or recent sessions.
• Quick text quoting: select text inside a timeline reply to create a quote snippet, with hover preview and more accurate scroll positioning.
• Built-in Mermaid rendering: diagrams support fullscreen zoom and panning, with an on-demand engine that cuts the main bundle from 1199 kB to 572 kB.
• Fullscreen table view: dialogs keep uniform safe margins on all four sides instead of overlapping system buttons.
• Panel-tab context menu: supports Close, Close Others, and Close to the Right.

Mini programs & extensions

• Parallel capability activation: mini programs start in parallel according to manifest capability dependencies for faster launches.
• Session Turn cancellation: mini programs gain a Session Turn cancellation API.
• Per-item AgentEvent authorization: full event permissions are double-checked against both manifest and persisted grants; newly added permissions are highlighted on update.
• MCP Resources & Prompts: the MCP client adds resource and prompt capability integration.
• Stable MCP configuration: config and business secrets move to a stable data directory and survive install-source switching.
• Canvas capability: adds a display-change event API and rounds out the game Canvas runtime.
• AppView breadcrumbs: preview/Diff return to the navigation stack, with page-owned breadcrumbs capped at depth 5.
• File picker: the Space switcher joins the search/sort row for smoother operation.

Platform & models

• Linux desktop integration: windows use a Finch-logo title bar, support Wayland, fall back automatically without a compositor, and gain an rpm packaging target.
• New model: GPT-6 Astra is available.
• Settings entry: Settings becomes its own sidebar button; the About page links straight to Settings and adds a "Learn more" link.

Under the hood & stability

• Persistent usage stats: model usage is written to a local cache and stays compatible across version rollbacks.
• SQLite migration: Space and session state move into SQLite storage for more stable history restoration.

Improvements

• Faster startup: workspace and model startup states are fetched in parallel with module loading.
• Renderer architecture refactor: reworks Renderer layering and long-session runtime resource ownership.
• Structured logging: fills in main-process log coverage for easier diagnosis.

Fixes

Follow-ups & compression

• Fixes interrupted follow-ups leaving old tasks running and stale round content behind.
• Fixes summary loss during repeated compression of very large contexts and duplicate reruns of manual and automatic compression.
• Fixes missing auto-compression when the context exceeds the limit and leftover state after compression failures.
• Fixes compression reruns mistaking cross-session reference material for a task to execute.

Background tasks & notifications

• Fixes background task results appearing after the wrong message.
• Fixes background notifications delivered across the wrong workspace, lost on reconnect, and per-message reply triggers.

Sessions & messages

• Fixes the UI not updating dynamically after switching the session language.

• Fixes blank Timeline restoration, lost progressive rendering, and trailing blank space after images load.
• Fixes anomalous LaTeX formula delimiter rendering.
• Fixes uncleared input after skipping an interaction and leftover answers after switching sessions.

UI & platforms

• Fixes stacked dialogs where Escape closed the wrong underlying dialog and inner dialogs were obscured; text areas now fill their container by default.
• Fixes Windows/Linux session layout and title-bar drag regions covering control buttons.
• Fixes sub-pixel gaps between diff lines and missing timeline dialog animations.

Models & accounts

• Corrects oversized GPT context-window configuration and misleading Kimi quota-exhaustion messaging.
• Fixes Finch Plan usage grouping, vision capability, and address concatenation.

Mini programs & MCP

• Fixes mini program pages missing a cwd fallback and being unrecoverable when the directory name and identifier mismatch.
• Fixes MCP tool-list truncation, state cross-contamination with the mini program list, and missing reactivation after recovery.
• Fixes today's usage not refreshing after reopening and reconnect/overload copy covering run status.

1.6.1 Changelog

New

Thinking & models

• Professional thinking mode: adds a professional mode with deeper reasoning for complex tasks.
• GLM 5.3 lineup: enables GLM 5.3 and adds a GLM 5.3 Flash model entry.

Home & appearance

• Home section customization: reorder and show or hide Home sections.
• Help & feedback menu: adds Help and Feedback submenu entries to the sidebar main menu.
