Removed Changes

Reduced false-positive bash permission prompts — tree-sitter parsing now handles find -exec, variable assignments, command substitutions, and many other patterns that previously triggered unnecessary prompts. Also fixed tree-sitter not loading in npm-installed versions
Changed tool search to bypass the third-party proxy gate when the environment variable is set (replaces CLAUDE_CODE_PROXY_SUPPORTS_TOOL_REFERENCE, now removed)
Added claude plugins as an alias for claude plugin
Improved claude plugin validate to explain that marketplace.json source paths are relative to the repo root when rejecting ../ paths

Filter by Platform

Added6 changes

•Added w key in /copy to write the focused selection directly to a file, bypassing the clipboard (useful over SSH)
•Added optional description argument to /plan (e.g., /plan fix the auth bug) that enters plan mode and immediately starts
•Added ExitWorktree tool to leave an EnterWorktree session
•Added CLAUDE_CODE_DISABLE_CRON environment variable to immediately stop scheduled cron jobs mid-session
•Added lsof, pgrep, tput, ss, fd, and fdfind to the bash auto-approval allowlist, reducing permission prompts for common read-only operations
•Added support for marketplace git URLs without .git suffix (Azure DevOps, AWS CodeCommit)

Improved6 changes

•Improved /config — Escape now cancels changes, Enter saves and closes, Space toggles settings
•Improved up-arrow history to show current session's messages first when running multiple concurrent sessions
•Improved voice input transcription accuracy for repo names and common dev terms (regex, OAuth, JSON)
•Improved bash command parsing by switching to a native module — faster initialization and no memory leak
•Improved marketplace clone failure messages to show diagnostic info even when git produces no stderr
•Improved CPU utilization in long sessions

Fixed31 changes

•Fixed tool search to activate even with ANTHROPIC_BASE_URL as long as ENABLE_TOOL_SEARCH is set.
•Fixed slow exits when background tasks or hooks were slow to respond
•Fixed agent task progress stuck on "Initializing…"
•Fixed skill hooks firing twice per event when a hooks-enabled skill is invoked by the model
•Fixed several voice mode issues: occasional input lag, false "No speech detected" errors after releasing push-to-talk, and stale transcripts re-filling the prompt after submission
•Fixed --continue not resuming from the most recent point after --compact
•Fixed bash security parsing edge cases
•Fixed several plugin issues: installation failing on Windows with EEXIST error in OneDrive folders, marketplace blocking user-scope installs when a project-scope install exists, CLAUDE_CODE_PLUGIN_CACHE_DIR creating literal ~ directories, and plugin.json with marketplace-only fields failing to load
•Fixed feedback survey appearing too frequently in long sessions
•Fixed --effort CLI flag being reset by unrelated settings writes on startup
•Fixed backgrounded Ctrl+B queries losing their transcript or corrupting the new conversation after /clear
•Fixed /clear killing background agent/bash tasks — only foreground tasks are now cleared
•Fixed worktree isolation issues: Task tool resume not restoring cwd, and background task notifications missing worktreePath and worktreeBranch
•Fixed /model not displaying results when run while Claude is working
•Fixed digit keys selecting menu options instead of typing in plan mode permission prompt's text input
•Fixed sandbox permission issues: certain file write operations incorrectly allowed without prompting, and output redirections to allowlisted directories (like /tmp/claude/) prompting unnecessarily
•Fixed prompt cache invalidation in SDK query() calls, reducing input token costs up to 12x
•Fixed Escape key becoming unresponsive after cancelling a query
•Fixed double Ctrl+C not exiting when background agents or tasks are running
•Fixed team agents to inherit the leader's model
•Fixed "Always Allow" saving permission rules that never match again
•Fixed several hooks issues: transcript_path pointing to the wrong directory for resumed/forked sessions, agent prompt being silently deleted from settings.json on every settings write, PostToolUse block reason displaying twice, async hooks not receiving stdin with bash read -r, and validation error message showing an example that fails validation
•Fixed session crashes in Desktop/SDK when Read returned files containing U+2028/U+2029 characters
•Fixed terminal title being cleared on exit even when CLAUDE_CODE_DISABLE_TERMINAL_TITLE was set
•Fixed several permission rule matching issues: wildcard rules not matching commands with heredocs, embedded newlines, or no arguments; sandbox.excludedCommands failing with env var prefixes; "always allow" suggesting overly broad prefixes for nested CLI tools; and deny rules not applying to all command forms
•Fixed oversized and truncated images from Bash data-URL output
•Fixed a crash when resuming sessions that contained Bedrock API errors
•Fixed intermittent "expected boolean, received string" validation errors on Edit, Bash, and Grep tool inputs
•Fixed multi-line session titles when forking from a conversation whose first message contained newlines
•Fixed queued messages not showing attached images, and images being lost when pressing ↑ to edit a queued message
•Fixed parallel tool calls where a failed Read/WebFetch/Glob would cancel its siblings — only Bash errors now cascade

Changed1 change

•Changed CLAUDE.md HTML comments () to be hidden from Claude when auto-injected. Comments remain visible when read with the Read tool

Other7 changes

•Restored the model parameter on the Agent tool for per-invocation model overrides
•Simplified effort levels to low/medium/high (removed max) with new symbols (○ ◐ ●) and a brief notification instead of a persistent icon. Use /effort auto to reset to default
•Reduced bundle size by ~510 KB
•VSCode: Fixed scroll speed in integrated terminals not matching native terminals
•VSCode: Fixed Shift+Enter submitting input instead of inserting a newline for users with older keybindings
•VSCode: Added effort level indicator on the input border
•VSCode: Added vscode://anthropic.claude-code/open URI handler to open a new Claude Code tab programmatically, with optional prompt and session query parameters
