 # Disable TokuDB since 10.1.12 on F>=28
 #   It will either "freeze" the testsuite (probabbly stuck in some loop) or ~500 TokuDB tests will fail
 #   This issue is probabbly caused by updates in Fedora Rwahide (F28) KOJI - like a new GCC and many build tools updates

+* Thu Jan 25 2018 Michal Schorm <mschorm@redhat.com> - 3:10.2.12-4
+- Fix the upgrade path. Build TokuDB subpackage again, but build a unsupported
+  configuration by upstream (without Jemalloc).
+  Jemmalloc has been updated to version 5, which isn't backwards compatible.
