OIS 1.2 was released some months ago, and it builds cleanly with current ois.spec; repoquery reports only two packages relying on it:
[guido@localhost ~]$ repoquery --whatrequires --alldeps ois ois-devel-0:1.0-5.fc11.x86_64 chess-0:1.0-24.fc11.x86_64 ogre-samples-0:1.6.1-3.fc11.x86_64
would an update to upstream 1.2 be feasible in the next future?
