on GitHub

What's changed

• Added env var CLAUDE_CODE_ENABLE_TASKS, set to false to keep the old system temporarily
• Added shorthand $0, $1, etc. for accessing individual arguments in custom commands
• Fixed crashes on processors without AVX instruction support
• Fixed dangling Claude Code processes when terminal is closed by catching EIO errors from process.exit() and using SIGKILL as fallback
• Fixed /rename and /tag not updating the correct session when resuming from a different directory (e.g., git worktrees)
• Fixed resuming sessions by custom title not working when run from a different directory
• Fixed pasted text content being lost when using prompt stash (Ctrl+S) and restore
• Fixed agent list displaying "Sonnet (default)" instead of "Inherit (default)" for agents without an explicit model setting
• Fixed backgrounded hook commands not returning early, potentially causing the session to wait on a process that was intentionally backgrounded
• Fixed file write preview omitting empty lines
• Changed skills without additional permissions or hooks to be allowed without requiring approval
• Changed indexed argument syntax from $ARGUMENTS.0 to $ARGUMENTS[0] (bracket syntax)
• [SDK] Added replay of queued_command attachment messages as SDKUserMessageReplay events when replayUserMessages is enabled
• [VSCode] Enabled session forking and rewind functionality for all users
