- Retains all crawler request, profile cleanup, teardown, and compact publication fixes from v3.7.9.
- Aligns release metadata on
3.7.10.
- Compact publication tests must pass with a read-only source.
- The helper must run successfully with production Python 3.6 before publication.
- No database migration is required.
