What
The library Claude Code bundles for checking that data has the right shape can now recognise two more text formats: MAC addresses (the hardware address of a network device) and credit card numbers. Its error messages in other languages gained matching labels, and it gained wording for the size of map-style data.
Why
This comes with a library update and has little direct effect on how you use Claude Code.
