version for Ubuntu 21.04

is there already a release date planned for a new version to be compatible with Ubuntu 21.04?
The current version 3.21.4 cannot be installed in Ubuntu 21.04

error: ubuntu-21.04 version is not supported, so all dependencies may not be installed. However trying to install using ubuntu-20.10 version packages.

And trying to install using ubuntu-20.10 version packages does end up in missing dependencies:
