rust-v0.142.2 Jun 25, 2026

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 respect_system_proxy is 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)

0.142.0

New Features

/usage can now show and redeem earned usage-limit reset credits, with confirmation, retry, and refreshed availability states. (#28154, #28793)
/plugins now 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+Z and resuming with fg. (#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.md discovery, 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/list and thread/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)
