Some highlights…
[Hearthstone] Actually removed the tip that read, in part, “This tip was removed. Translators: please leave this blank.”
Truly? 
[Hearthstone] Fixed a bug where Splendiferous Whizbang only used the basic hero skins.
Interesting! Didn’t know it was a bug.
[Hearthstone] Whizbang the Wonderful has been reverted to its normal effect (it was temporarily changed due to March’s Twist season)
Yep, that settles it: Twist is over, but old Whizbang still has old decks - #2 by SparkyElf-2852
[Collection] Fixed a bug where there was only one non-golden Vampiric Blood granted in Core.
Oh, yes!
Not that a triple-blood DK looks attractive right now, but that was a bit of a shame (see ‘Known Issues’).
[Collection] Fixed a bug where players got an error message when attempting to craft certain Golden versions of Wild Demon Hunter cards.
Some people have been complaining about it for… I dunno, months?
One more small thing.
So, that holds, at least accroding to patch notes (which have not always reflected reality well).
Which isn’t even the biggest on, see, for example: Cockroach OTK Shaman is back...again
I translate: destroyed the deck/class completely.
Questionable point. I think it was more of a ‘fanservice’ to a vocal part of the community.
Which is more or less the only excuse for such a hasty and sloppy approach, bad not only for DH, but also for the meta in general, according to my projections.
