 - Small fixes in the test suite to make sure `plumed` is always invoked with `--no-mpi` when testing for features. This avoids
   problems that were appearing when testing with some specific versions of OpenMPI.

 - Added the possibility to disable `RTLD_DEEPBIND` (see \issue{952}).
 - Fixed a bug in `switchingfunction` mode `Q` thanks to @nm3787, (see #951)

 - Environment variables such as `PLUMED_INCLUDEDIR` and similar are sanitized before they are used for running commands.
 - Fixed a bug leading to a crash when using python selectors (e.g., `@mda:` or `@mdt:`) and multiple MPI processes per replica.
 - Fixed leaks in Subprocess, potentially givin problems with a large number (>250) of sequentially created plumed objects all of them using `@mda:` or `@mdt:` selectors.
+- Quantum Espresso patches have been fixed for a bug leading to incorrect masses passed to PLUMED and for a missing string terminator.
