This is a bugfix release, mainly restricting the adapter to C++11 features to keep the adapter compatible with older compilers (see issue #263, resolved by @davidscn with #264), as well as some documentation and CI updates by @MakisH (see all changes: v1.2.0...v1.2.1).
The version-specific branches (mainly for OpenFOAM.org) are not affected (in which case, see v1.2.0).
See you at the preCICE Workshop 2023! 🍻
