Tip: Cap Your `--settings` File Size — v2.1.214 Now Fails Fast on Anything Over 2 MiB

Claude Code Changelog·medium signal

Pointing `--settings` at a device file or a multi-GB file previously caused unbounded memory growth; v2.1.214 makes oversized (>2 MiB) settings files fail at startup with a clear error. If you generate settings programmatically in CI — merging plugin configs, permission rules, and env blocks — add a size assertion to your generator now, because the failure mode moved from a slow OOM to a hard startup refusal. The same release improves the `claude rc` workspace-trust error in the home directory to explain that trust there is never saved.
