   - Fixed a bug in EDS module for restarts, where accumulated rate was not stored to restart file, leading to convergence problems.
   - (developers) `plumed config makefile_conf` can be used to retrieve `Makefile.conf` file a posteriori.
   - Added patch for Quantum ESPRESSO 6.2 (thanks to Ralf Meyer).
+  - (developers) Store `MPIEXEC` variable at configure time and use it later for running regtests. Notice that in case
+    `MPIEXEC` is not specified regtests will be run using the command stored in env var `PLUMED_MPIRUN` or, if this is
+    also not defined, using `mpirun`.
+  - (developers) Added canonical makefile targets `check` and `installcheck`. Notice that `check` runs checks with
+    non-installed plumed whereas `installcheck` uses the installed one, including its correct program name if it
+    was personalized (e.g. with suffixes). Notice that this modifies the previously available `check` target.
