- Now that python3-clang uses libclang.so.XX and is versioned, we
provide a metapackage for it to replace existing installations.
- Merge llvm-LTO-devel into llvm-devel just like the underlying
versioned packages have been merged.
- Remove baselibs.conf: it didn't do anything, and we shouldn't
need any of these to be imported.
- Only suggest documentation packages.
- Update README.packaging to reflect the new packaging strategy.
We don't need to touch the old package on version updates any
longer, but we need to change the project configuration.
