DATA MANIFEST
Datasets and release history.
Every dataset with its licence and cadence, and every release with its actual first-publication time. Corrections are new releases; nothing is rewritten.

No publication archive exists before this service launched, and observation timestamps are never substituted for publication timestamps.
