Questions about the December 16th 2025 deadline for new DC apps

Hi,

I’m frantically trying to put together a new Jira DC app in time for the December 16th 2025 deadline for new DC apps (see here: From Data Center to Cloud: The Next Chapter for Marketplace Apps - @chrishemphill1).

What is the exact meaning of the deadline? Can I submit the initial version on December 15th? Or do I have to complete the DC certification and the marketplace review and approval by December 15th?

Background info: we’ve released a fancy new GitHub + Jira integration for Jira Cloud. We’re really happy with it, and we’d like to also get a Jira DC version of this same app published to help make it easier for customers to find and use our app while they themselves migrate off Jira DC.
