Yade 0.80

Yade version 0.80.0 is released.

Thanks all contributors. The main new feature is an optimized collider
(thanks to Bruno Chareyre):

  Improved usage of Verlet's distances allows running the collider at a
  lower frequency. Measured speedup up to x3 for large multi-threaded
  simulations (https://yade-dem.org/wiki/Colliders_performace).

It is mostly maintanance and bugfix release to make yade more stable,
faster and installable on most modern operating systems.

We tried to save backport-compatibility, so most of functionality is
saved, even if you update from 0.60-series.

The new tarball can be found as usuall in Download section on Launchpad [1].

Yade-stable package contains already the 0.80.0 version, so if you have
that PPA added, you should get an update "automatically". The new version
is already in Debian Sid available.

We strongly recommend you to use prepackaged version of Yade, if you do
not have any specific reasons to compile yade from scratch. It will help
to avoid many problems with compilation [2] and [3].

Thanks.

Anton
