Anthropic released Claude Code v2.1.288, introducing new features for mods and cloud sessions while addressing numerous stability issues with session resumption, permissions, and plugin handling.
- Added $.ui.selection() for mods to retrieve the last selected text in fullscreen mode.
- Added a built-in gh api to cloud sessions lacking the GitHub CLI and fixed control character sending.
- Fixed resume functionality dropping files, context, or thinking history from previous turns.
- Improved auto mode by compacting conversations that exceed the client-side safety classifier's limit.
- Fixed LSP tool calls hanging indefinitely by introducing a 60-second timeout per server.
The update enhances reliability for long-running sessions and plugin interactions while providing better accessibility support through screen reader improvements.
