About this release

Since v0.20.5 (v2026.8.19, tagged August 21), this window landed ~1,313 commits across ~1,557 files (+177,113 / −21,682) — ~525 merged PRs including consent-gated real-profile browsing (use your default Chromium profile for local browsing, with Windows close-with-approval flow); the desktop Browser getting its own OS window plus a managed SSH remote-update engine and fleet profile rail; a large remote MCP catalog expansion (50+ live-verified vendor-hosted servers incl. Cloudflare, Grafana Cloud, Better Stack, Railway); TTL result caching for web_search/web_extract; lean-tail compression as the default; multi-query tool_search with stemming; opt-in OS-keychain encryption for stored secrets (no more per-launch macOS Keychain prompts); updaters pausing gateways over the control socket instead of tree-killing them; image/package-managed installs refusing unsafe in-place updates (#91277 Phase 3); cron durable-incident acks and clearer code-skew failures; Slack link-unfurl controls; shared Docker container identities; pluggable terminal environment backends; and new models across the pickers (GLM-5.3-Flash, MiniMax M3 free, MiniMax H3 Max video).
