This release introduces significant new capabilities, including an experimental 'plan' approval mode and the addition of the 'generalist' agent, while enabling Agent Skills by default. Numerous stability fixes address OOM crashes, PTY descriptor leaks, and automation loop issues. Performance has also been improved with optimizations for handling large text inputs.
