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)
