I have just updated to the latest TW20170123 and I have noticed some changes on clang and llvm both for 3.8 and 3.9. Also there are a lot of conflicts like: File /usr/share/doc/packages/llvm/html/_sources/Phabricator.txt from install of llvm3_8-devel-3.8.1-6.1.x86_64 (repo-oss) conflicts with file from install of llvm3_9-devel-3.9.1-2.1.x86_64 (repo-oss) where v3.8 has files conflicting with v3.9, i.e. the opposite of what I reported yesterday. Is this to be expected?
