Since libode is in Universe, this seemed worth passing on. 0.5 is what we
have in the archives currently. If 0.8 shows up somewhere we ought to be
careful before we synch it/upload it.

libODE (libode0-dev, libode0c2) is a free, industrial quality library for
simulating articulated rigid body dynamics - for example ground vehicles,
legged creatures, and moving objects in VR environments. It is fast,
flexible, robust and platform independent, with advanced joints, contact
with friction, and built-in collision detection. It is used by many games,
as the trends are to provide more realistic behaviour of the engines every
time. While version 0.5 has been in the archive for a while, most of the
newer games demand version 0.8.
There is an ABI breakage between de 0.5 and the 0.8 release of libode. In
fact, there are numerous reports of incompatibilities between versions in
the forums, and the upstream developers apparently don't care at all about
SONAMEs ( [image: [WWW]]
Upstream are using the version number as a SONAME, so it seems they
no clue on what they're doing. Even though 0.5 and 0.8 are clearly not
ABI-compatible (segfault), the major number of the SONAME seems to be the
Trying to upgrade to 0.8, and not being fully aware of the problem. we
uploaded a newer version of libode0c2, based on the 0.8 version of ode. It
seems to have been a bad idea, since programs depending on it seem to break.
Thus, we wanted to ask what would be the best way to face this transition.
We should also contact the maintainers of the packages that depend on this
to try to make the transition as easy as possible for everyone.
Packages that depend on libode0c2: python-pyode, xmoto, python-soya,
python-pyepl, and indirectly:

How is the proper way to handle this?
