Detailed Description

All llvm sub-projects in Fedora will be updated to version 20, and there will be a soname version change for the llvm libraries. There will be an llvm19 compat package added to ensure that packages that currently depend on clang and llvm version 19 libraries will continue to work. Any compatibility packages we add for Fedora 42 will be retired or orphaned before the Fedora 43 branch date. As stated in the LLVM-19 change proposal, we plan to retire or orphan these older compatibility packages prior to the Fedora 42 branch date:

• llvm18
