Re: dovecot 2.4 changes

18 Feb 2026


      I'd like to give a feedback on the issue I was struggling with.
The online configuration converter helped me to sort out any remaining
problems after manual adjustments. The permission problems probably arised
because passwd wasn't defined properly and hence I guess it couldn't
properly attach uid to a given user. Now that the config has been properly
converted, things are running fine.
Thank you Aki for the online converter: it was quite useful. Pointed out
some things I missed after reading documents.

Again, to reiterate once more in this thread, 2.4 **is** major release.
The versioning scheme is generation.major.minor.patch, so 2.4.0.0 is the
full version number for 2.4.0, we just drop the last .0 as it's not really
a patch release.

I was reading documentation and converting my config step-by-step. There
were a bunch of error messages to sort out. Most of them I could, but
there are permission issues preventing the upgrade. I'm not an IT
illiterate and maintaining servers for 20+ years. But this one gives me
headaches. Again: I did RTFM.
There was a recent post by Curtis, so my problems may be syntax related
after all and not about permissions in any way.
So despite of reading release announcements and all sorts of
documentations, it is still not straightforward. And I am not the only
one
according to the list.
I go with Marek. These changes would have provided enough a reason for a
major version bump, not from 2.3 to 2.4. And it would have been good to
indicate deprecated configuration options before or provide config
backward compatibility or conversion. Not to break nearly every config
as
it was.

 Hello,

 it may be true the change was announced long time before, but me
 personally also did not notice and was quite surprised. If there
is
such
a big compatibility change I would expoect major version number
change
(3.0) not a minor (2.4) which evokes some higher progress but not
the
configuration compatibility change.
 I would also expect on such change if the software accepts also
old
config for some time and logs about deprecated config. Just to
get
prepared. I accept there could be reasons which did not allow
authors
to
do it like that.

Every major release or point release always comes with a Release
Announcement and if there are any breaking changes, they are always
listed.
Your expectations as stated are personal. The developers just do
their
thing as always.
Before any upgrade/update, always refer to the Release
Announcement!
