Do we need a new column that captures the publication date of each AVA's revision, or is the revision history string is enough?

The new column would be publication_date and would have the same dates as the revision history string, which can be repetitive. However, if those dates are needed for a specific purpose, it can be more convenient.

+1 for the new property!

Although redundant at times it would make it much easier to filter the AVAs based on this column rather than having to parse a string, especially if the data is in an actual database.
