API v2 threads can now inject dynamic tools at startup and route their calls/responses end-to-end through the server and core tool pipeline. (#9539)
Added filtering on the thread list in the app server to make large thread sets easier to browse. (#9897)
Introduced a thread/unarchive RPC to restore archived rollouts back into active sessions. (#9843)
MCP servers can now define OAuth scopes in config.toml, reducing the need to pass --scopes on each login. (#9647)
Multi-agent collaboration is more capable and safer, with an explorer role, better collab event mapping, and max-depth guardrails. (#9817, #9818, #9918, #9899)
Cached web_search is now the default client behavior. (#9974)

Bug Fixes

Fixed a TUI deadlock/freeze under high streaming throughput by avoiding blocking sends on the main Tokio thread. (#9951)
The web_search tool now handles and displays all action types, and shows in-progress activity instead of appearing stuck. (#9960)
Reduced high CPU usage in collaboration flows by eliminating busy-waiting on subagents. (#9776)
Fixed codex resume --last --json so prompts parse correctly without conflicting argument errors. (#9475)
Windows sandbox logging now handles UTF-8 safely, preventing failures when truncating multibyte content. (#8647)
request_user_input is now rejected outside Plan/Pair modes to prevent invalid tool calls. (#9955)

Documentation

Updated the contribution guidelines for clearer onboarding and workflow expectations. (#9933)
Refreshed protocol/MCP docs to reflect thread/unarchive and the updated request_user_input question shape. (#9843, #9890)

Chores

Self-update via Homebrew now uses an explicit cask upgrade command to avoid warnings and ambiguity. (#9823)
Release packaging now consistently writes the bundle zip to dist/. (#9934)
Updated key dependencies in the Rust workspace (including axum, tracing, globset, and tokio-test). (#9880, #9882, #9883, #9884)
Aligned feature stage naming with public maturity stages and added clearer warnings for underdevelopment features. (#9929, #9954)
