Patch 9.2.5
new mounts listed by source
Patch 9.2.5 is a minor patch, but it still introduces at least six handsome new mounts: two racial mounts are available at launch, and the other four PvP mounts will be available when Season 4 arrives (which will be later in the patch). There's also evidence of a seventh, encrypted 'slime cat' mount, but we aren't yet sure when that will become available.
