It is a pleasure to announce three new PLUMED releases!
Release 2.6.1 is a maintenance release on the 2.6.x branch and includes updated GROMACS patches.
Release 2.5.5 is a maintenance release on the 2.5.x branch.
Release 2.4.8 is a maintenance release on the 2.4.x branch.
They all solve minor bugs (see changes for 2.4.8 here).
