Notes (MR and issue comments): force re-rendering
Closes #348 (closed)
All known Heptapod instances are small enough that we don't need to make this a post-install background migration.
Since the testing down at the time of Heptapod 0.16 is now a bit old, I've retested again with a MR having a system note (list of commits due to rebase) rendered before I launched the migration. Re-rendering occured as expected both in the interface and the database.
