My advice would be to hold off on the 2.3.x to 2.4.x upgrade for the forseeable future. This upgrade involves a great many changes to dovecot.conf and the files in conf.d: The very grammar of these files.
Thank you for your advice. I'm aware of the significant changes between the 2.3.x and 2.4.x versions. I've been preparing accordingly and am not concerned by the challenges these changes may bring. For example, we work on smaller mail servers for non-profits and NGOs, where we know all the users personally. This allows us to clone the entire setup and thoroughly test everything in advance including with them.
So to answer your question, my advice is not to upgrade in the next 14 days, or even the next month or two, regardless of any 2.4.2 progress. I just don't want to livecycle stuff (a few servers are EOL now) and stay on 2.3.x for no reason beside getting into the new config. My primary concern is potentially encountering subtle bugs that may have already been patched in the development branch but aren't yet included in version 2.4.1 (or similar). If these bugs could easily be avoided by waiting just a few more days for a more stable release... therefore my question.
@aki and the other developers: Thank you. Dovecot remains an OUTSTANDING piece of software, and I am incredibly grateful that it exists as open-source, even if I have to migrate my configs :-D.
Without it, these mentioned environments serving the public good would struggle to maintain their own high-quality communication infrastructure without relying on third-party providers like Microsoft Exchange Online, which could pose political challenges for certain NGOs. The same applies to smaller businesses out there.
On a related note, I appreciate how Proxmox VE offers its community subscription[1] for € 115/year & CPU socket without adding any extra support services. This model allows organizations, even those with limited budgets, to contribute a little bit directly to the project in a straightforward way.
There is nothing comparable I can simply buy from OX for a few EUR per month per organization, isn't it? (sorry for the direct CC at Aki, but I want to make sure this question is not read over)
