Why it matters
Temporal replaces the Date object for timezone-aware, calendar-aware date handling without external libraries. Breaking changes in native module compatibility demand immediate testing before production upgrades.

Adopt Temporal for new date logic; it replaces custom helper libraries developers are already writing. Rebuild all prebuilt native add-ons before upgrading to 26. Worth trying now if you can absorb NODE_MODULE_VERSION bump in your native deps.
