New
- Smarter NES rebase — Rebase logic now detects when you're typing in agreement with a suggestion and handles it more intelligently.
- Pending commit handling — Chat sessions now properly handle pending commits for worktree changes.
Fixed
- NES debounce and language context — Fixed cancellation token handling that was preventing proper debounce and context fetch behavior.
- Server response handling — NES no longer errors when the server response contains no choices.
- Prompt variable naming — Adopted renamed prompt/instructions variable IDs.
Breaking Changes
- MCP support disabled in CLI — Model Context Protocol support has been disabled in the command-line interface.
