The official release of GROMACS 5.1.5 is available!
This release fixes a few code issues found since 5.1.4, in particular that PME tuning with the group scheme had been working incorrectly (and is now disabled). We encourage all users of the 5.1 series to update to 5.1.5. Please see the link to the release notes below for more details.
This is the last release that will be made from the 5.1.x series, which is now over two years old. Resources are limited, and unfortunately we cannot maintain all of our annual releases indefinitely. All future fixes will take place in more recent series.
You can find the code, documentation, release notes, and test suite at the links below.
