Patch 8.2.0.19506

 is a Hearthstone patch released June 1, 2017. It is a large patch, adding all data for the Deck Importing feature, the permanent Friendly Feud feature, and many other features and some bugfixes.

New features

 * Deck Importing – It’s now possible to copy and import Hearthstone decklists! It’s fast and easy to share your decklist with friends, or try the latest decklist from your favorite streamer, pro, or fansite.
 * Copy a deck by selecting the hero portrait at the top in your collection and pressing the copy button.
 * Hearthstone knows when a valid decklist is copied, and you’ll be asked if you want to use it when you create a new deck.
 * Quests with friends – Most quests can now be completed during Friendly Challenges with players on your Friends list.
 * We’ve added the following card back: The Magic of Dalaran – Acquired by achieving Rank 20 in Ranked Play in June.
 * When viewing “Pick a Replacement” from a deck recipe or imported decklist, the ghosted card on the left now takes you directly to Crafting mode.
 * It is now possible to refine searches in the Collection manager with the ‘Type:’ and ‘Rarity:’ search tags.
 * Error messages received when searching the Collection Manager are now more helpful.
 * Golden cards and non-golden cards will now share the same slot in a decklist.
 * Ranked wins for each hero will now tally beyond 500.
 * Alternate Heroes, such as Maiev, will now have golden borders once 500 wins have been achieved for a Class.
 * You can now drag a golden card out of your Arena deck to "de-goldenize" it.
