   - \ref CS2BACKBONE (isdb module) is now mpi parallelised in particular with DOSCORE and CAMSHIFT
   - \ref SAXS (isdb module) there is an additional implementation based on bessel functions that can be faster for large systems (new keyword BESSEL) 
   - Libmatheval is not used anymore. \ref MATHEVAL (and \ref CUSTOM) are still available
-    but employ an internal implementation of the lepton library. There should be no observable difference
-    except from the fact that lepton does not support some of the inverse and hyperbolic functions supported
-    by matheval (easily writable as a function of the available ones). Notice that \ref MATHEVAL (and \ref CUSTOM)
-    switching functions using the lepton library have been further optimized with respect to PLUMED 2.4.
+    but employ an internal implementation of the lepton library.
+    Functions available in libmatheval and absent in the original lepton library have been added so as to have backward compatbility.
+    `atan2(y,x)` function has also been added.
+    Notice that MATHEVAL (and CUSTOM) \ref switchingfunction "switching functions"
+    using the lepton library have been further optimized with respect to PLUMED 2.4.
     Finally, notice that it is possible to use asmjit to optimize performance (see \ref Lepton).
   - Implemented bash autocompletion, see \ref BashAutocompletion.
   - \ref MOLINFO now allows selecting atoms from chains with a numeric ID (see \issue{320}).
