The end of Dovecot Director?

I recently stumbled upon the following commit on the Dovecot core Github repository: https://github.com/dovecot/core/commit/4a187116dc2311804be22724007d357323005...

Apparently, Dovecot Director is going to be removed in the next major version of Dovecot and the commercial Dovecot cluster architecture will be its successor: https://github.com/dovecot/documentation/blob/a85b742ec4fc2744db30a6943b3c25...

This would be a huge blow for many organizations around the world that are currently using Dovecot with Director in a shared storage environment.

Can anyone of the Dovecot developers maybe enlighten us about the future of Dovecot?

• Will there still be the Director feature in the next community release of Dovecot?
• If not, will there be a community feature that is on par with the current Director feature?
• For how long will Dovecot version 2.3 still be supported (security fixes, bug fixes)? Is there any EOL plan?

Thanks for any clarification! Steff
