Claude Code 2.1.245 fixes Linux startup crash

By RepoJournal · Filed · About Anthropic

Arch Linux users can stop fighting the terminal: Claude Code just patched the glibc 2.44 crash that was bricking startup.

Claude Code v2.1.245 fixes a startup crash on Linux distributions shipping glibc 2.44, which includes Arch Linux, CachyOS, and Fedora Rawhide [1]. The fix ripples across the entire stack: the Agent SDK TypeScript release jumped to v0.3.245 for parity with Claude Code v2.1.245 [2], and the Claude Code action rolled through three releases in rapid succession, v1.0.203 through v1.0.205, to stay aligned [3]. The Python SDK and base action both synced to the same CLI version, with the Python package bumping its bundled CLI to 2.1.245 [4]. The release notes confirm the fix is targeted, and the team didn't pad the changelog with anything else. If you're on any of those affected distros, this is your patch. Everyone else can treat this as a routine maintenance sync across the Anthropics ecosystem, backed by 6 releases and 17 commits this period.
