[Dune] [Dune-Commit] dune-istl r1027 - releases/1.2.1/istl/paamg

[Martin Nolte]

Hi Markus, hi all,

since this mail went to all Dune developers, I will place the answer here. 
Dune 1.2 has been released already. Hence I think we should not make any 
changes to this branch anymore.

You said your students are using Dune 1.2. Either they are using the published 
tar balls or they are using the svn version. In the first case, simply merging 
to 1.2 would not help because we don't build new tarballs all the time. In the 
second case, they can just switch to the current 1.2.1 bug fix branch to get 
the newest patches.

Maybe the real question is whether we should publish the latest bug fixes as 
soon as possible. On this question I would call for the opinion of the 
developers. In any case, it is probably a good idea for everybody to look for 
patches that should be in 1.2.1 and are not, yet.

Yours,

Martin
