* New features - Availability of DIRE NLO parton shower (cf. arXiv:1705.00742). This is not (yet) the default shower, in particular not in NLO-merged configurations. - Higher numerical stability in parton shower kinematics (re)construction. - Add OVERWEIGHT_THRESHOLD allowing user to cap maximal weight during event generation (cf. manual). - Avoid spuriously large weights in NLO-merged samples due to instable PDF ratios. - Add interface for hadron-level selectors. - Add Max_N_TChannels option in Amegic. - Add possibility to identify partons which originate in the hard decay handler. - Restructure gzip support such that it can be switched off at runtime (USE_GZIP). - Enable on-the-fly reweighting for calculations with the Higgs (Interference) add-on for HIGGS_INTERERENCE_MODE 1, 2, 3 or 4.
* Bugfixes - Bugfix in NLO-matched parton shower emission for non-trivial colour structures like in V+2jAATTNLO.

In addition the ld.so.conf.d file is also renamed to follow the shared lib version to make it possible to install multiple versions of the shared lib.- Rebase SHERPA-MC-no-return-in-non-void-function.patch and add fixes for one more function showing the same issue in version 2.2.4.- GCC >= 6.0 required, build fails with older GCC for openSUSE <= 1320.
