Public bug reported: Zesty currently has GROMACS 2016.2 which has been reported to have a quite important usability bug. Under certain (not uncommon) circumstances the mdrun simulation tool of GROMACS can deadlock and hang before exit, for more details see the release notes (and the bug report linked there): http://manual.gromacs.org/documentation/2016.3/ReleaseNotes/release-notes.html#fixed-mdrun-with-separate-pme-ranks-hanging-upon-exit
The bugfix (along with a few other minor fixes) has been released in the GROMACS 2016.3 patch release. This is a small release with only ~20 commits (see the full release notes below or at http://manual.gromacs.org/documentation/2016.3/ReleaseNotes/release- notes.html). To avoid including a known buggy GROMACS version in Ubuntu 17.04, I'd like to have a freeze exception made and the gromacs* packages bumped to 2016.3. If not done, the usability of the gromacs package will be limited (given the bug causing deadlock).
