Changelog

Improvements

• Continued split Gemini and Vertex Gemini responses automatically using provider continuation tokens. (#55056)
• Added settings.encoding with zstd, gzip, and none values for provider, model, and variant HTTP request bodies. ChatGPT authentication defaults to Zstandard compression when no custom baseURL is set. Thanks @esafak. (#54932)
• Added provider-level compatibility defaults and compatibility.cacheFormat for Anthropic- and Alibaba-style prompt-cache markers. (#54911, #54945)
• Added official WinGet packages and WinGet-aware upgrade and uninstall support. (#54808)
• Raised the default streamed-chunk timeout from 5 to 15 minutes for models that pause while reasoning. (#55032)

Bug fixes

• Disabled Bun’s fetch idle timeout for provider requests, preventing long-running streams from ending early. (#55007)
• Preserved mixed CRLF and LF line endings when the edit tool changes files. (#53166)
• Preserved unknown V1 OpenAI-compatible model options in migrated request bodies. (#54694)
• Stopped querying Azure resources during startup; Azure connections now ask for the resource name directly. (#54870)
• Loaded the system configuration directory at the lowest precedence. Thanks @rntdrts. (#54921)
• Installed the native CLI and extracted ripgrep without PowerShell on Windows ARM64. (#54955, #54981)

Improvements

• Added the post-update highlights dialog, /highlights, and the highlights alert setting. (#54969)

Bug fixes

• Restricted slash-command autocomplete to the start of the prompt. Thanks @OpeOginni. (#54857)
• Reported x64 emulation correctly when the TUI runs on Windows ARM64. (#54984)
• Removed the stale todowrite label from tool output. (#53966)

Improvements

• Added per-project auto-accept permission overrides under Settings → Projects, with mod+shift+a controlling the current project. (#54839)
• Added a native Windows (ARM64) option to the download page. (#54971)

Bug fixes

• Bundled native ARM64 terminal and CLI binaries in Windows ARM64 desktop builds, and moved emulated x64 installations to native ARM64 updates. Thanks @mweinbach. (#54689, #54983)
• Included subagent sessions in displayed session costs. (#55052)
• Loaded image and audio attachments in the review panel and opened video previews in an in-window theatre view. (#55015, #54696)
• Showed submitted prompts immediately and kept the Working marker above undelivered steers. (#54047, #55023)
• Fixed tab closing when collapsed side-panel tabs exist and restored focus correctly after stacked dialogs close. (#54695, #55038)

Improvements

• Added request-body encoding and model/provider cache-format fields to generated client types. (#54932, #54945)
• Exported CredentialApi from the Promise client API. (#52797)

Improvements

• Added an optional official Figma plugin with its MCP connection and six bundled Figma skills. (#55049, #55061)
• Exposed credential.activate to Effect and Promise server plugins. Thanks @remorses. (#52797)

Bug fixes

• Converted rejected Promise-based plugin tools into normal tool failures instead of crashing their execution path. (#54913)
• Fixed the VS Code extension launching the V2 CLI with the removed --port argument. Thanks @uyencss. (#49084)

Improvements

• Added the built-in Code Mode tools opencode.worktree_create, opencode.worktree_list, and opencode.worktree_remove. Removing a worktree requires edit approval, and force: true can discard modified or untracked files. (#53981)
• Added confirmation before opencode pair --remote first enables internet access, plus --yes/-y for scripts and other non-interactive use. (#54561)
• Automatically archived projects when all known directories disappear. Reopening a project restores it, while surviving clones and linked worktrees keep it active. (#54354)
• Raised the ChatGPT OAuth input limit for gpt-6.1-sol and gpt-6.1-sol-fast to 500,000 tokens. (#54668)
• Added Vertex AI routes for Interactions and Mistral models. (#54175, #54058)

Bug fixes

• Fixed updater detection for symlinked home directories and package-manager installations, increased probe timeouts, and now report unavailable updates clearly when the installation method cannot be detected. (#54609, #54622, #54672)
• Fixed GitHub Copilot routing for Gemini, Anthropic, and Responses models when live model metadata is unavailable, and accepted interleaved Claude reasoning values. (#54208, #54210, #54201)
• Fixed Google Vertex Application Default Credentials when CLOUDSDK_CONFIG points to a custom gcloud configuration directory. Thanks @H-Max. (#54164)
• Prevented ChatGPT token-sharing sessions from sending unsupported mid-session reasoning-effort updates. (#54085)
• Blocked file:// access through Code Mode’s fetch, which now returns a clear filesystem-access error. Thanks @ferdinandyb. (#54510)
• Fixed remote workspace file operations so driver-provided filesystem overrides are used correctly.
• Preserved subagent notifications when location services are evicted, and propagated well-known configuration updates across locations with bounded HTTP timeouts. (#54072, #53821)

Bug fixes

• Displayed session execution failures that occur before or between model steps directly in the timeline. (#53826)
• Preserved a saved session’s unavailable model selection instead of silently replacing it with a fallback. (#53822)
• Added syntax highlighting for C++ module interface files such as .cppm, .ixx, and .cxxm. (#53853)
• Summarized integrations with multiple credentials as a connection count, preventing long labels from crowding the integration name. (#54054)

Improvements

• Made the web app installable from Chrome and Edge, including deployments behind cookie-based authenticating proxies. (#53905)
• Updated the session column layout and text wrapping for clearer long content. (#54020)

Bug fixes

• Displayed session execution failures that occur before or between model steps directly in the timeline. (#53826)
• Fixed command-palette selection so newly arriving higher-ranked results become active until you explicitly choose a result. (#54275)
• Preserved bold, code, emphasis, and strike-through formatting inside Markdown link labels. (#54451)
• Fixed timeline file links and complete patch rendering, including unusual filenames and patches whose original alignment can be reused. (#53641, #54017)
• Showed complete tool error text when an error is expanded. (#53816)
• Fixed browser-panel controls, page visibility, corner masks, and closed side-region overlays. (#53907, #54038, #52461, #54052)
• Made the third-party notices dialog scrollable. (#53911)

Improvements

• Added startup plugin seeding to Effect embedded hosts and workerd through OpenCode.create({ plugins }) and OpenCodeWorkerd.create({ plugins }).
• Re-exported WorkspaceDriver, EnvironmentDriver, and EnvironmentFiles from @opencode/sdk/effect.

Bug fixes

• Ensured embedded hosts activate supplied plugins before model discovery, generation, and recovery begin. (#54219)

Improvements

• Extended BridgeLayout with viewport dimensions and optional border information so native extension surfaces can track window resizing and preserve rounded card borders.

Bug fixes

• Kept desktop browser-panel corner masks and borders aligned while resizing or using custom themes. (#52461)
• Kept the browser site button clickable after the embedded page takes focus. (#53907)

Improvements

• Added Google Cloud credentials (gcloud auth or environment) to the Vertex connection flow, with project and location choices discovered from environment variables, gcloud configurations, and Application Default Credentials. (#53798)
• Reduced session snapshot overhead, accelerated multi-file restores, made capture resilient to crashes and concurrent processes, and added lossless background packing of snapshot objects. (#51996)
• Added Step 5 Preview Free to OpenCode’s free models for a limited time and removed the retired Fledge Alpha Free listing.

Bug fixes

• Prevented working-tree diffs from timing out or stalling the server in repositories with many untracked files by batching Git operations. (#53449)
• Fixed large revert selections failing when their paths exceeded the operating system’s command-line limit. (#53956)
• Fixed snapshot and undo handling for literal filenames containing Git pathspec characters, corrupted or locked snapshot indexes, concurrent captures, and project directories whose names begin with ... (#51996)
• Changed opencode service remote-access URLs to use a persistent random subdomain rather than a predictable route. Disabling and re-enabling remote access generates a new address. (#53962)

Improvements

• Enabled OSC 8 hyperlinks in more terminals, including VS Code and other xterm.js terminals, Zed, mintty, and newer VTE terminals; FORCE_HYPERLINK=1 now overrides terminal detection. (#53904)

Bug fixes

• Fixed transcript links not opening when clicked, including URLs wrapped across multiple rows. (#53903)
• Kept activity summaries in place when expanding or collapsing details with session.verbosity: "low". (#52357)
• Prevented the home-screen version footer from overlapping keyboard hints in short terminals. Thanks @fihaaade. (#53891)
