•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)

Improved6 changes

•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

Fixed15 changes

•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

Changed1 change

•Changed default Opus model on Bedrock, Vertex, and Microsoft Foundry to Opus 4.6 (was Opus 4.1)

Removed1 change

•Deprecated /output-style command — use /config instead. Output style is now fixed at session start for better prompt caching

Other1 change

•VSCode: Fixed HTTP 400 errors for users behind proxies or on Bedrock/Vertex with Claude 4.5 models
