Claude Code v2.1.117 is now available with significant improvements to performance, plugin management, and user experience. This release focuses on making your development workflow smoother and more reliable.

What’s New

Enhanced Plugin Management

Plugin installation has been streamlined with automatic dependency resolution. When you install an already-installed plugin, missing dependencies are now automatically installed instead of stopping with an “already installed” message. The new blockedMarketplaces and strictKnownMarketplaces managed settings are now enforced across all plugin operations.

Improved Performance

Startup times have been significantly reduced when using both local and claude.ai MCP servers, thanks to concurrent connection handling being enabled by default. On macOS and Linux native builds, the Glob and Grep tools have been replaced with embedded bfs and ugrep through the Bash tool, eliminating separate tool round-trips for faster searches.

Better Session Management

The /resume command now intelligently offers to summarize large, stale sessions before re-reading them, matching the behavior of the --resume flag. Model selections in /model now persist across restarts even when projects pin different models, and the startup header clearly shows whether the active model comes from a project or managed-settings pin.

Subagent Configuration

Forked subagents can now be enabled on external builds by setting the CLAUDE_CODE_FORK_SUBAGENT=1 environment variable, providing more flexibility for advanced users.

Enhanced Effort Levels

Pro and Max subscribers using Opus 4.6 and Sonnet 4.6 now get high effort by default (previously medium), providing better performance out of the box.

Bug Fixes

  • Fixed OAuth sessions dying with “Please run /login” errors when tokens expire
  • Resolved WebFetch hanging on very large HTML pages
  • Fixed crashes when proxies return HTTP 204 No Content
  • Improved prompt-input undo functionality
  • Better handling of NO_PROXY settings under Bun
