Changelog

What's changed

Added source path metadata to images dragged onto the terminal, helping Claude understand where images originated
Added clickable hyperlinks for file paths in tool output in terminals that support OSC 8 (like iTerm)
Added support for Windows Package Manager (winget) installations with automatic detection and update instructions
Added Shift+Tab keyboard shortcut in plan mode to quickly select "auto-accept edits" option
Added FORCE_AUTOUPDATE_PLUGINS environment variable to allow plugin autoupdate even when the main auto-updater is disabled
Added agent_type to SessionStart hook input, populated if --agent is specified
Fixed a command injection vulnerability in bash command processing where malformed input could execute arbitrary commands
Fixed a memory leak where tree-sitter parse trees were not being freed, causing WASM memory to grow unbounded over long sessions
Fixed binary files (images, PDFs, etc.) being accidentally included in memory when using @include directives in CLAUDE.md files
Fixed updates incorrectly claiming another installation is in progress
Fixed crash when socket files exist in watched directories (defense-in-depth for EOPNOTSUPP errors)
Fixed remote session URL and teleport being broken when using /tasks command
Fixed MCP tool names being exposed in analytics events by sanitizing user-specific server configurations
Improved Option-as-Meta hint on macOS to show terminal-specific instructions for native CSIu terminals like iTerm2, Kitty, and WezTerm
Improved error message when pasting images over SSH to suggest using scp instead of the unhelpful clipboard shortcut hint
Improved permission explainer to not flag routine dev workflows (git fetch/rebase, npm install, tests, PRs) as medium risk
Changed large bash command outputs to be saved to disk instead of truncated, allowing Claude to read the full content
Changed large tool outputs to be persisted to disk instead of truncated, providing full output access via file references
Changed /plugins installed tab to unify plugins and MCPs with scope-based grouping
Deprecated Windows managed settings path C:\ProgramData\ClaudeCode\managed-settings.json - administrators should migrate to C:\Program Files\ClaudeCode\managed-settings.json
[SDK] Changed minimum zod peer dependency to ^4.0.0
[VSCode] Fixed usage display not updating after manual compact
