I think it is quite pity we ship version marked "alpha". We ship alpha/beta version for some time already so I'll rather ask upstream what distributions should do.
There is only tiny API change which should not cause troubles, see the release notes [1] (grep for: lzma_allocator const). The commit [2]. I'll attach pkgdiff analysis later. Library analysis: $ repoquery_rawhide -q --provides xz-libs.x86_64 | tee xz-libs.provides liblzma.so.5()(64bit) liblzma.so.5(XZ_5.0)(64bit) liblzma.so.5(XZ_5.1.2alpha)(64bit) xz-libs = 5.1.2-15alpha.fc22 xz-libs(x86-64) = 5.1.2-15alpha.fc22 Package xz-libs 5.2.0 will provide 'liblzma.so.5(XZ_5.0)'. No package requires 'liblzma.so.5(XZ_5.1.2alpha)'. The only package seems to require 'xz-libs = 5.1.2' (repoquery_rawhide -qR perl-Compress-Raw-Lzma). $ repoquery_rawhide --archlist src --whatrequires xz-static supermin-0:5.1.11-1.fc22.src The only package seem to src require 'xz-static' (supermin). At the end: only 'supermin' and 'perl-Compress-Raw-Lzma' needs to be rebuilt for 5.2.0 (STABLE!) rebase.
