New Features

  • MCP tools now use tool search by default when supported, improving tool discovery while preserving compatibility with older models and providers.
  • macOS authentication clients can honor system proxy, PAC, and WPAD settings when respect_system_proxy is enabled.
  • Plugins can provide dedicated dark-mode logos through local manifests and remote catalogs.
  • Apps can display richer safety-buffering UI using server-provided visibility and faster-model metadata.

Bug Fixes

  • Remote plugin catalogs now return curated featured-plugin rankings.
  • Expired Amazon Bedrock credentials now produce actionable recovery guidance instead of a generic authorization error.
  • Remote stdio MCP servers now accept absolute working directories written in the remote platform’s path format.
  • Remote HTTP(S) image inputs now return clear model-visible validation errors; inline data URLs and local images remain supported.
  • PowerShell commands containing executable AST regions the safety classifier cannot inspect now require approval.
  • Code Mode now warns when the selected model lacks the required metadata.

Chores

  • Updated bundled OpenSSL and esbuild dependencies to patched releases.
  • Successful formatter runs are now quiet while failures still show diagnostics.
