I created the v1.18.x branch along with v1.18.0 rc1: https://github.com/ofiwg/libfabric/releases/tag/v1.18.0rc1 All additional changes that will target the v1.18 release will need to be cherry-picked for the v1.18.x branch. My target date for the final release is April 7, with rc2 this Friday (24th) or Monday (27th). Thanks, - Sean
