It's fixed as of nine minutes ago: https://github.com/anthropics/claude-code/pull/16686
What a lazy commit message, "Update CHANGELOG.md", no mention of the "why" at all. Even the PR description is blank.
Lol a formatting error in a change log breaking the entire thing
Genuinely curious how a date in the subheader of a changelog could have broken the CLI
edit: it seems changelog.md is assumed to be structured data and parsed at startup, and there are no tests to enforce the changelog structure: https://github.com/anthropics/claude-code/issues/16671
