Changelog

New updates and improvements to OpenCode

  1. v2.2.5

    Percentage Compaction Buffer

    Set "compaction": { "buffer": "20%" } in opencode.json to keep a share of each model's context window free, so one setting fits models with small and large windows. Token counts still work.#60647

    Improvements

    • CoreWhen read misses because a folder is missing, the error names that folder and the nearest one that exists.#60688
    • CoreWhen edit can't find oldString, the error shows the file's closest lines, or says the change is already there.#60689
    • CoreCalls to a tool named bash now run as shell instead of failing, with the same permissions. A plugin tool actually named bash still takes precedence.#60687

    Fixes

    • CoreMCP servers that send stdio messages larger than 10 MiB no longer get disconnected, and large messages are read much faster.#60694
    • CoreIdle locations no longer restart their MCP servers right after shutting down.#60668
    • CoreCompaction now caps its prompt at the model's context window when the input limit is larger.#60660
    • CoreLiteLLM context window errors now trigger compaction instead of stopping the session.#60692
    • CoreReasoning is no longer turned into plain text when you switch models or resume an interrupted response, which caused request errors on some providers.#60498
    • Terminal, DesktopThe connect menu no longer lists MCP servers, which are managed in their own place.#60675
  2. v2.2.4

    Publish Interactive Artifacts

    Enable "experimental": { "artifacts": true } in opencode.json to let agents publish, update, and serve HTML or static artifacts through the built-in local provider or plugin-provided storage.#60351

    Improvements

    • CoreMade enabled schedules run under opencode serve and coordinated multiple server processes so a schedule fires only once. Schedules remain opt-in through experimental.schedules.#60478
    • CoreRaised OpenCode Go limits for DeepSeek V4.1 Flash.#60625
    • SDKExtended client.experimental.persistentPty.update to rename terminals or clear a user title, and exposed userTitle plus persistent-pty.updated events.#60329

    Fixes

    • CoreAllowed user, project, and remote configuration to override Console-supplied provider names, limits, variants, settings, and headers.#60597
    • CoreKept local OpenCode service requests out of environment-configured proxies.#60441
    • CoreReplaced Claude Code’s misleading /login instruction with claude auth login.#60592@Tarquinen
    • TerminalPreserved prompt cursor styles applied by plugins when themes or unrelated prompt state change.#60599
    • TerminalAdded missing right padding to edit and patch diffs.#60614
    • TerminalExtended the vertical session-tab activity pulse across the full tab width.#60338
  3. v2.2.3

    Use Claude Code in OpenCode

    Install Claude Code, run claude auth login, then select Claude Agent in /connect to use your Claude Code login and models.#58782

    Breaking changes

    TUI plugins require OpenTUI 0.8

    @opencode/plugin now requires @opentui/core and @opentui/solid 0.8.0 or later. In OpenTUI 0.8, a ScrollBox's wrapper, viewport, content, and scrollbars are facade objects instead of renderables, and a custom RenderContext must implement clock and onAnimationTick. See the OpenTUI 0.8.0 release notes.

    #60385

    Managed policy: integration.use covers integrations only

    integration.use now controls which integration accounts can be used, and the new mcp.use, skill.use, and plugin.use actions control MCP servers, skills, and plugins. Rules with the old mcp:, skill:, and plugin: resource prefixes are converted automatically, but a bare integration.use rule no longer applies to MCP servers, skills, or plugins.

    #60315

    Improvements 7

    • CoreAdded Code Mode JavaScript checks to experimental schedules, including statically authorized tool calls, persistent state, and custom wake messages.#60140
    • CoreAdded separate managed-policy actions for connecting to integrations and using integrations, MCP servers, skills, and plugins.#60315
    • Terminal, SDKAdded lazy loading for stored image references when experimental.media_blob is enabled. Images are downloaded only for previews, while undo, revert, fork, and prompt recall restore referenced attachments safely.#60116
    • TerminalAdded a distinct marker for the selected composer suggestion in the new designs.#60393
    • SDKPreserved partial LLMResponse output on AIError.partial when generation, object generation, or a tool loop fails.#60477

    Fixes 13

    • CorePreserved plugin-provided model variants and delayed dynamic provider fallback until external SDK hooks have run.#60097#60380
    • CorePreserved permission reasons and feedback in MCP failures, and made Code Mode failures match direct tool-call failures.#60102#60109
    • CoreFixed invalid Code Mode schedule checks so creation fails immediately and existing invalid checks pause without repeated execution.#60349
    • CoreRemoved a session’s persistent terminals when the session is deleted.#60322
    • CoreKept nested tool progress from replacing the parent execute call rows.#60480
    • TerminalFixed PHP syntax highlighting for code blocks without an opening <?php tag.#60359
    • TerminalPreserved # in file-search paths unless it introduces a valid line range.#60336
    • TerminalKept the configured default cursor style after config reloads.#60302
    • TerminalMatched the search cursor to the highlighted row when a selection dialog has no query.#60310
    • SDKMatched the Promise AI client more closely to the Effect API and accepted typed tools in loops.#60465#60390
    • SDKKept tools whose execute handler can throw available to the AI client.#60431
    • SDKContinued polling queued media generations when providers return unknown intermediate statuses.#59988
    • SDKStopped sending an incompatible filename alongside file_url on OpenAI Responses requests.#60382
  4. v2.2.2

    Image Generation by Default

    When a connected provider supports image models, agents can now use experimental_image_generate without additional configuration. Set its preferred model through experimental.image_generate.model.#60258

    Improvements

    • CoreRecorded the start time of each session’s latest execution.
    • SDKAdded if and until inputs for client.experimental.schedule.create, plus schedule check results and output fields.#60137
    • SDKExposed SessionInfo.time.busy for the latest execution’s start time.
    • SDKAdded optional source metadata to prompt file attachments.

    Fixes 7

    • CoreRejected persistent terminal requests whose working directory no longer exists.
    • CorePreserved media when sessions are forked or imported.
    • CoreAssociated image-generation notices with the correct background job.
    • TerminalPreserved captured attachments and their original source paths.#60222@OpeOginni
    • TerminalPrevented middle-truncated paths from overflowing at very narrow terminal widths.
    • TerminalImproved Go usage-limit messages with the reset time and account page link.
    • TerminalCorrectly typed and displayed Go and ChatGPT usage-limit errors.
  5. v2.2.1

    Keep Working Toward a Goal

    Run /goal <objective> in the TUI or Desktop to let the session continue until a reviewer confirms the objective is met. Use /goal pause, /goal resume, or /goal clear to control it.#59437

    Generate Images

    Enable experimental.image_generate to let agents create or edit images with the new image_generate tool. You can optionally set its default model with experimental.image_generate.model.#59939#60096

    Improvements 8

    • SDKExpose compaction through the Promise AI client.#59987
    • SDKAdd freeform tool support and Responses routes for OpenRouter, DigitalOcean, and Venice.#59963#59991

    • CoreRetry provider throttling correctly instead of reporting it as context overflow.#59649
    • CoreSend image-edit references and image sizes in the formats expected by OpenRouter, Google, and Vercel Grok.#60067#59927

    • TerminalImprove spacing in an empty /usage dialog.#59918@Tarquinen
  6. v1.19.5
  7. v2.2.0

    Create, install and share Desktop plugins (experimental)

    Add experimental image and decision generation APIs to plugins and sdk

    Add experimental image and decision generation APIs to plugins and sdk, allowing image generation or decision model (think typesafe, clef, etc) workflows.#59190#59380#58758

    Plugins can now attach and update keyed session instructions with ctx.session.instructions.entry.put/list/remove

    Plugins can now attach and update keyed session instructions with ctx.session.instructions.entry.put/list/remove. Instead of editing the system prompt and busting the prompt cache, each change is added as a small update at the next step. The entries also survive compaction and reverts, and they don't start an extra model turn.#56550

    Add configurable prompt cache TTLs per provider/model

    #59157

    Breaking changes

    TUI plugins require OpenTUI 0.7

    @opencode/plugin now requires @opentui/core and @opentui/solid 0.7.0, up from 0.6.8 or later. Plugins that depend on OpenTUI 0.6 fail to install until they upgrade. In OpenTUI 0.7, custom renderables read their hooks from their class at construction: assign renderBefore, renderAfter, and onLifecyclePass in the constructor instead of as class fields, call refreshHooks() after adding a hook by reflection, and replace defineNativeIntegration() with a static nativeIntegration declaration. See the OpenTUI 0.7.0 release notes.

  9. v1.19.3

    Improvements

    Improvements

    • CoreConfigure model reasoning options to generate reasoning variants, replacing catalog variants while preserving your configured variant overrides.
  10. v1.19.2

    OpenCode 1 now stays on the 1.x release line

    OpenCode 1 now stays on the 1.x release line: update checks use only the npm opencode-ai latest version, so 1.x installs are never offered a 2.x build as a regular update.

    Fixes

    • CoreUpgrading to OpenCode 2 remains a separate, explicit choice through the 2.0 offer in /update or opencode upgrade --major.
    • CoreFix upgrades for installs managed by yarn.
    • CoreSkip 1.x updates for Homebrew Core installs, which now track OpenCode 2, and check tap and Chocolatey availability before offering an update.
    • CoreThe install script refuses to install 2.x versions.
