I've created this page with a table as an addendum to Talk:Chromium Browser#Telling_version_numbers_from_build_numbers. Since talk page entries should not be modified, then the table is better here.
I first created the table for my own use to tell where files supplied with only Chromium builds stand with regards to screenshots that actually do have their Chromium versions specified.
The table has not yet reached the desired level of completeness.
