Dear NEST Developers, For the last few days, all CI builds on macOS have failed. This is most likely due to Homebrew now providing libomp 15.0 instead of 14.0, see issue #2515 (https://github.com/nest/nest-simulator/issues/2515). I have temporarily disabled OpenMP-dependent tests for the macOS builds (#2516). Please pull current master into all open PRs so that most of the macOS tests can run. Please note that considerable recent improvements in the code base (systematic use of nullptr #2496, of "and" and "or" instead of && and || #2498, removal of "void" arguments, systematic use of "override" and removal of "virtual" where not needed #2493; removal of unused imports #2490 as well as #2479) may lead to some merge conflicts. Please resolve them in the spirit of the new style and consult the listed PRs if in doubt about what is the new style.
