   * Improve the distance search in water bridge analysis with capped_distance (PR #2480)
 
 Changes
+  * Removes the `nproc` keyword from
+    :class:`Waterdynamics.HydrogenBondLifetimes` as the multiprocessing functionality
+    did not work in some cases(Issues #2511).
   * Added `min_mass` parameter to `guess_hydrogens` function in `HydrogenBondAnalysis`
     set to 0.9 by default (Issue #2472)
   * Removes `save()` function from contacts, diffusionmap, hole, LinearDensity,
