GROMACS 2021.5 patch release available

Hi GROMACS users,

The official release of GROMACS 2021.5 is available!

This patch release fixes several issues found since the initial release of GROMACS 2021 (including, e.g., the way the DeltaH contribution from PME is accounted for when running AWH with FEP). We encourage all users of the 2021 series to update to 2021.5. Please see the link to the release notes below for more details.
