Hearthstone got patched and is now at version 4.2.0 and this brings some long overdue tweaks and the ability to pre-purchase the new expansion.
Patch 4.2.0 lets you unlock up to 18 deck slots by unlocking all nine heroes. There’s now a Deck Recipe mode that lets newer players quickly build a deck that is playable. You can read more about Deck Recipes here.
Also after introducing 3 paid hero portraits earlier, you now have the ability to unlock a new Paladin hero portrait in the form of Lady Liadrin. Lady Liadrin can be unlocked for free by anyone who reaches level 20 in World of Warcraft with a new character.
Whispers of the Old Gods will be released late April or early May.
Full patch notes for 4.2.0 can be viewed here.
Hearthstone: Heroes of Warcraft is available on PC, Mac, Android, and iOS devices.
