Changelog

What's changed

  • Added modelOverrides setting to map model picker entries to custom provider model IDs (e.g. Bedrock inference profile ARNs)
  • Added actionable guidance when OAuth login or connectivity checks fail due to SSL certificate errors (corporate proxies, NODE_EXTRA_CA_CERTS)
  • Fixed freezes and 100% CPU loops triggered by permission prompts for complex bash commands
  • Fixed a deadlock that could freeze Claude Code when many skill files changed at once (e.g. during git pull in a repo with a large .claude/skills/ directory)
  • Fixed Bash tool output being lost when running multiple Claude Code sessions in the same project directory
  • Fixed subagents with model: opus/sonnet/haiku being silently downgraded to older model versions on Bedrock, Vertex, and Microsoft Foundry
  • Fixed background bash processes spawned by subagents not being cleaned up when the agent exits
  • Fixed /resume showing the current session in the picker
  • Fixed /ide crashing with onInstall is not defined when auto-installing the extension
  • Fixed /loop not being available on Bedrock/Vertex/Foundry and when telemetry was disabled
  • Fixed SessionStart hooks firing twice when resuming a session via --resume or --continue
  • Fixed JSON-output hooks injecting no-op system-reminder messages into the model's context on every turn
  • Fixed voice mode session corruption when a slow connection overlaps a new recording
  • Fixed Linux sandbox failing to start with "ripgrep (rg) not found" on native builds
  • Fixed Linux native modules not loading on Amazon Linux 2 and other glibc 2.26 systems
  • Fixed "media_type: Field required" API error when receiving images via Remote Control
  • Fixed /heapdump failing on Windows with EEXIST error when the Desktop folder already exists
  • Improved Up arrow after interrupting Claude — now restores the interrupted prompt and rewinds the conversation in one step
  • Improved IDE detection speed at startup
  • Improved clipboard image pasting performance on macOS
  • Improved /effort to work while Claude is responding, matching /model behavior
  • Improved voice mode to automatically retry transient connection failures during rapid push-to-talk re-press
  • Improved the Remote Control spawn mode selection prompt with better context
  • Changed default Opus model on Bedrock, Vertex, and Microsoft Foundry to Opus 4.6 (was Opus 4.1)
  • Deprecated /output-style command — use /config instead. Output style is now fixed at session start for better prompt caching
  • VSCode: Fixed HTTP 400 errors for users behind proxies or on Bedrock/Vertex with Claude 4.5 models
