Claude Code 2.1.245 Fixes a glibc 2.44 Startup Crash

2026-08-25 ยท source:

Claude Code 2.1.245 fixes a startup crash affecting Linux distributions that ship glibc 2.44, including Arch Linux, CachyOS, and Fedora Rawhide.

What it is

Claude Code 2.1.245 is a maintenance release of Anthropic's CLI coding agent.

What it does

It fixes a crash on startup that hit any Linux distro shipping glibc 2.44, naming Arch Linux, CachyOS, and Fedora Rawhide specifically as affected.

Why it matters

Rolling-release distros ship new glibc versions fast, so a bug like this quietly locks out an entire slice of the Linux user base until someone traces it back to the libc version.
