These are the draft release notes for ESPResSo 5.0.1 (milestone).

ESPResSo 5.0.1

This release provides a number of corrections for the ESPResSo 5.0 line. We recommend that this release be used for all production simulations. The interface has not been changed between ESPResSo 5.0.0 and 5.0.1. However, some bugs were discovered which can affect simulation results. Please find the list of changes below. The numbers in brackets refer to ticket numbers on https://github.com/espressomd/espresso

Bug fixes

  • Dihedral bonds checkpointing was fixed (#5279). A regression introduced in 5.0.0 prevented the checkpointing mechanism from reloading dihedral bonds.
  • Missing feature guards in the short-range loop that prevented compiling ESPResSo were added (#5274). Only affected the compilation of ESPResSo when configured with -D ESPRESSO_BUILD_WITH_SHARED_MEMORY_PARALLELISM=ON and with a custom myconfig.hpp file that contained a small number of features.
  • The Lees-Edwards boundary conditions restriction was lifted from cluster analysis function (#4965)
