[Opensim-dev] Raise minimum mono version to 2.6

Sun Jan 27 14:32:49 UTC 2013

If, as we both agree, OpenSim works differently with different versions of
mono then people are going to report bugs that exist when OpenSim is run on
mono versions prior to 2.10 that don't exist with mono version 2.10 and
later.

How many people are there in the OpenSim dev community that still actively
use a mono version prior to 2.10? In fact, AFAIK, many devs are already
looking to see when they can safely move to mono 3.0. So, who is going to
work on fixing bugs that no longer exist with mono 2.10 and later? If no
ones is going to work on doing that then we can't honestly say that mono
2.6 or 2.8 are still supported.

If we intend to have new OpenSim users, we should have them using the mono
version with which they'll get the best experience with the existing /
future code base. It doesn't help anyone if they use an outdated version of
mono and find that the problems they encounter aren't going to be addressed
because they no longer exist with newer versions of mono.
