Being no Redmine master, I did perform the bulk-edit manually the first releases around, until 3.13 where I finally thought the ticks on the left side might be helpful to get several tickets edited at once… and researched it.

It’d be great to have a quick mention of that being possible in the post release steps (when moving tickets from Fix-committed to Resolved, and when updating the target version for other tickets). I know tickets with relationships to others can be a pain for the first one, and one might have to iterate until every remaining ticket can have its status switched; but at least the target version move should be made trivial…
