This is a small but critical patch for people using Claude Code on modern, fast-updating Linux systems. If you aren't on one of those specific setups, this release doesn't change much for you, but it's still safe to update.
Fixes
- Fixed a crash that happened right when you opened the app on certain Linux distributions. These specific systems (like Arch Linux, CachyOS, and Fedora Rawhide) recently updated a core background tool called "glibc" (which helps software run basic tasks) to version 2.44. That update caused Claude Code to break on startup, but it's fixed now.
Breaking changes
No breaking changes in this release.
