I think it would be quite nice to have an ‘update log’ for each item.
When you update a theme you specify why it’s been updated:
- Updated functionality
- Bug fix
- Minor update
Maybe a section of the site for items which have had the functionality updated. This would encourage authors to update items.
Maybe authors get an email when an item they have purchased has been updated with a bug fix.
I realise this might be open to abuse, but I think the reviewer who approves the update could confirm the items functionality has genuinely been updated.
