dolfin-stable still exists. dolfin-stable is simply the latest release
with backported bugfixes found in the further development of DOLFIN. So
rather than getting the latest release, it's better to get dolfin-stable.
But no new development will happen in dolfin-stable.

dolfin-stable can be accessed here:

>From a functionality point of view, dolfin-stable has the functionality of

development tip as possible.

So from a solver module/application developer's point of view, if you want
to develop your application against the latest release of DOLFIN, get
dolfin-stable, and if you want to develop your application against the
development version of DOLFIN, get dolfin-fsi.
