Iain Lane published an update on the upcoming Ubuntu Linux 21.10 Impish Indri release.

Impish Indri (to be 21.10) now in Feature Freeze

Hello Ubuntu developers,

As per the release schedule, Impish Indri is now in Feature Freeze.
Ideally, you will all now be focusing on bug fixing and not on getting new features into the release. However, if necessary, please follow the process for freeze exceptions:

https://wiki.ubuntu.com/FreezeExceptionProcess

As is the custom, packages that have been uploaded to impish-proposed prior to the feature freeze deadline, but have gotten stuck there, remain candidates for fixing between now and release.

Remember that version strings don't matter for Feature Freeze. If you upload a new upstream release and it has no new features then you don't need an exception. If you add a debian/patch that adds a new feature, or enable one via build flags then you do. We care about the content of the archive, not about precisely how things got there.

On behalf of the Ubuntu Release team,
