[gmx-users] what is the difference between the 2016.x and the 5.x series?

[Jose Borreguero]

Dear Gromacs users,

I'm a relatively new user of Gromacs and recently realized there is a
"2016" branch that is still being updated. What is the difference with the
5.x branch?

I ask because I could find RPM packages only for the 2016 version, much
easier to install than building from source.

Best,
.Jose
