What
The embedded build constants moved to 2.1.223 with a new build time and git sha.
Details
- roughly 80 changes in this group are the version constant being re-inlined at each use site
- also cosmetic: the
/whiteboard and /prototype command names moved to shared constants - an attachment schema moved into its own module
- several React-compiler memo caches were renumbered
Evidence
