Performance Improvements
Fixed Startup Performance Issues with Saved Hook Context
This release resolves critical performance bottlenecks that occurred when resuming sessions containing saved_hook_context. Previously, users experienced significant delays during startup when Claude Code attempted to restore sessions with complex hook configurations. The fix optimizes the context restoration process, resulting in much faster startup times and a smoother development experience.
This improvement is particularly beneficial for:
- Power users with extensive hook configurations
- Teams working with large codebases that rely on custom hooks
- Developers who frequently pause and resume their Claude Code sessions
How to Update
To update to Claude Code v2.1.29:
- Close your current Claude Code session
- Download the latest version from the official repository
- Follow the standard installation process for your operating system
- Restart Claude Code to benefit from the performance improvements
Existing sessions with saved_hook_context will automatically benefit from the performance optimizations upon restart.
