The title is very clear what it is. It's nothing new. I've been doing it every 14 days for the last year or so.
3: I don't own itch. I don't dictate what a devlog is posted as on your feed. "Update" is for devlogs. "Updated" is for new content releases. Take it up with itch.

5: I post a devlog every 14 days not once a week.
6: If none of the above is acceptable, #please let me know.
All the best, RogueOne.
