Download Claude Code 2.1.73

- 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
