GROMACS 2022.5 release notes#

This version was released on TODO, 2023. These release notes document the changes that have taken place in GROMACS since the previous 2022.4 version, to fix known issues. It also incorporates all fixes made in version 2021.6 and earlier, which you can find described in the Release notes.

Fixes where mdrun could behave incorrectly#

Add missing net charge term when running PME on a GPU#

When PME was running on a GPU, the term due to a net charge of the system was missing. In normal runs this only changed the potential energy by a constant, which is usually not relevant. In free-energy calculations where the net charge of the systen changes, the would lead to incorrect dV/dlambda and Delta lambda values (but one should anyhow avoid changing the net charge of a system with free-energy calculations).

Issue 4668

Fixes for gmx tools#

Fixes that affect portability#

Miscellaneous#

Improve muParser detection and bumped internal version to v2.3.4#

Update internal muParser version that include all changes made by us. Use muParser’s CMake config to detect external muParser. Update required version for external muParser to match the internal version.
