Collection version history¶

(draft)

Background: desired API features (see #13109, #13494)

• Get current + previous versions of a collection with a single API call
• Search all current + previous versions of collections with a single API call
• Stable small numeric "version number" for each version of a given collection

Implementation TBD

• Store all versions in the collection table (much easier to do paging)
• Flag to include/exclude old versions
