A version is a claim
A release announcement may mention larger counts or new features. Those statements require definitions: does a record count refer to unique verified items, imported candidates or published detailed profiles? Unclear metrics produce a false impression of progress.
Good release hygiene
Maintain a manifest listing published pages, dataset timestamps, revisions and exact checksums. Separate content changes from code changes. Include known limitations and unresolved issues beside new capabilities.
What to preserve
An archived manifest and build revision should make it possible to inspect the state readers actually saw at publication time, rather than a database that continuously rewrites the past.
Source and revision record
Original editorial analysis and definitions. For background reference, consult the source catalog.
