Version 1.9.3

Open hosted release notes once after each extension update, with a preference to turn them off.
Schedule matching CLI runtime updates after managed agent processes exit, with versioned installations, validation, retry limits and an opt-out.
Add opt-in Jev 1.14 image fallback for unsure text decisions through TypeSafe or OpenRouter, with small screenshots, persistent image request caps and a shared decision deadline.
Make the extension panel consistent at narrow widths and across views, with clearer connection/setup guidance and expandable diagnostics and memory controls.

All 22 changes

Refresh matching store descriptions, three screenshots and Chrome promotional tiles using the production panel with example data.
Correct Firefox compatibility metadata to advertise desktop support only.
Register native hosts for targeted setup, avoid duplicate native Codex registrations, preserve nested configuration during migration, and check the clients actually configured.
Document sparse Codex marketplace installation and validate setup from the published package layout.
Restrict download events to their originating controlled tab and session, remove the unused downloads permission, and redact private URL components and local directory paths.
Prevent one session from taking another session's tab without release.
Restore temporary headers, user-agent overrides, preload scripts, and media settings on finalization; retain failed cleanup for retry.
Redact private URL components from network observation and report environment configuration failures.
Compare visible controls and bounded PNG screenshots with session-scoped baselines and pixel-diff artifacts.
Discover and inspect frames with explicit depth/count limits, bridge Firefox frame identities across reconnects, and discover experimental WebMCP tools without execution.
Name tab groups on session creation and propagate URL policy to controlled popups, redirects and frame inspection.
Add a local first-run guide and optional background release notes, plus a reproducible target-selection fixture benchmark.
Extract browser expressions and observation projection into focused modules and expand lint coverage.
Complete the strict TypeScript migration for the CLI, native runtime and both extension builds; validate message and stored-memory boundaries.
Defer CLI command modules and local model libraries until needed, and scope child-process cancellation with Effect.
Preserve typed embedding rows, account for repeated resource URLs correctly, and reject disconnected Firefox requests immediately.
Expand lint to all production TypeScript and verify the installed package’s public declarations.
Update runtime dependencies and pinned release actions, migrate to Effect 4, and remove obsolete development helpers.

Version 1.9.2

Build both Chromium and Firefox extensions before release package validation.
Include pending AMO versions in submission retry checks to prevent duplicate uploads.
Update package and extension release versions to 1.9.2.
Reuse preinstalled Chrome on Windows, cache the Chromium headless shell on Linux/macOS, and cancel superseded PR checks.

Version 1.9.1

Shared Chromium and Firefox extension builds, with Firefox/LibreWolf discovery, Mozilla native-host registration, and a loopback WebDriver BiDi backend behind the existing browser tools.
OpenAI Luna Decisions through OpenRouter, retaining local fallback and bounded candidate validation. Screenshot sharing is separately opt-in.
A compact extension operating panel with expandable diagnostics, consistent controls, and automatic light/dark themes.
Transactional setup for all detected supported harnesses and applicable native hosts through setup --all.

All 6 changes

Restored README branding, browser install badges, download charts, and collapsed harness guides.
Firefox PR validation and listed AMO release automation with source archives and retry checks.

Version 1.8.0

Selectable harness setup, explicit targets, configuration overrides, dry runs, file rollback, selected-client skills, and graceful restart choices.
Checked compilation and declarations, compiled native-host distribution, untracked generated extension output, maintenance gates, and package smoke checks.
Full-stack developer snapshot foundations with branch channels and isolated state. Extension reload remains manual.
Experimental, explicitly enabled Jev text decisions through TypeSafe or OpenRouter, plus clearer popup provider controls. Luna remains unavailable preview support.

Corrected transitive ZIP dependency pinning and safer build publication.

Keep your tools in step.

Published installations can update the local runtime to match the extension. Check Settings → Updates. Updates wait for managed agent processes to exit; running sessions keep their version.

First time using automatic updates?

Run setup once from the current release:

npx -y opencode-chromium@latest setup --all

When current work has finished, reopen your browser and agent app to load the new updater. Development checkouts and pinned commands stay under your control. No browser or agent app is forcibly restarted.

Prefer fewer tabs? Turn off Show release notes after updates in the extension’s setup guide.
