# 0.143.0-alpha.26
Release 0.143.0-alpha.26
# 0.142.2
New Features
- MCP tools now use tool search by default when supported, improving tool discovery while preserving compatibility with older models and providers. (#29486)
- macOS authentication clients can honor system proxy, PAC, and WPAD settings when
respectsystemproxyis enabled. (#26709) - Plugins can provide dedicated dark-mode logos through local manifests and remote catalogs. (#29488)
- Apps can display richer safety-buffering UI using server-provided visibility and faster-model metadata. (#29473)
Bug Fixes
- Remote plugin catalogs now return curated featured-plugin rankings. (#29485)
- Expired Amazon Bedrock credentials now produce actionable recovery guidance instead of a generic authorization error. (#28992)
- Remote stdio MCP servers now accept absolute working directories written in the remote platform’s path format. (#29493)
- Remote HTTP(S) image inputs now return clear model-visible validation errors; inline data URLs and local images remain supported. (#29417, #29419)
- PowerShell commands containing executable AST regions the safety classifier cannot inspect now require approval. (#24092)
- Code Mode now warns when the selected model lacks the required metadata. (#29490)
Chores
- Updated bundled OpenSSL and esbuild dependencies to patched releases. (#29487, #29489)
- Successful formatter runs are now quiet while failures still show diagnostics. (#29467)

New Features
/usagecan now show and redeem earned usage-limit reset credits, with confirmation, retry, and refreshed availability states. (#28154, #28793)/pluginsnow organizes remote plugins into OpenAI Curated, Workspace, and Shared with me sections, while eligible turns can recommend and install relevant plugins. (#26703, #28399, #28400, #27704, #28403)- Configurable rollout token budgets track usage across agent threads, provide remaining-budget reminders, and abort turns when exhausted. (#28746, #28494, #28707, #29423)
- App-server clients can configure multi-agent delegation as disabled, explicit-request-only, or proactive at the thread and turn level. (#28685, #28792, #29324)
- Added an indexed web-search mode that permits live searches while restricting direct page access to server-approved URLs. (#28489)
- Codex can now receive scheduled UTC time reminders and query the current time directly, including through client-provided app-server clocks. (#28822, #28824, #28835, #29011)
Bug Fixes
- Restored reliable Linux TUI rendering after suspending with
Ctrl+Zand resuming withfg. (#28342) - Exec-server processes and stdio MCP sessions now survive transient disconnects, including signed-URL refresh and retry-safe stdin writes. (#28512, #28374, #28546, #28895)
- Remote environments now preserve executor-native paths, shells,
AGENTS.mddiscovery, and sandbox behavior across operating systems. (#28146, #28152, #28958, #28983, #29099, #29108, #29113, #29424) - Plugin loading and installation now handle root marketplace layouts, manifest fallbacks, multiple skill paths, actionable download errors, and immediate tool refreshes. (#28771, #28789, #28790, #28863, #28951)
- Parent agents now receive terminal subagent errors instead of seeing failed work as an empty successful completion. (#28375)
- Goal-first threads are once again persisted and returned by
thread/listandthread/search. (#28808)
Chores
- Reduced startup and session latency by deferring unnecessary DNS work, warming the model cache, reusing parsed plugin skills, parallelizing skill metadata reads, and skipping redundant catalog synchronization. (#28542, #28699, #28844, #29326, #29005)
- Reduced persistent-log churn by removing per-event WebSocket payload logging and filtering duplicated telemetry records. (#29432, #29457)
