Custom Games API:
- Added GetDedicatedServerKeyV2 which utilizes a new approach for securing/generating the keys. Any custom game that relies on GetDedicatedServerKey to communicate with its backend will want to switch to the V2 version as soon as possible.
- To give custom game authors time to switch to the new system, GetDedicatedServerKey will remain unchanged until 3/31/2019, after which will be automatically switched to V2.
- When playing on local/unofficial servers, GetDedicatedServerV2 will return special values to make the state more clear for developers (e.g. “Invalid_NotOnDedicatedServer”).

Added some previously unavailable heroes to Ability Draft
* Beastmaster (Hawk is not draftable)
* Lone Druid
* Io
* Monkey King (Primal Spring is not draftable)
* Shadowfiend (Shadowraze Medium and Presence of the Darklord are not draftable)
* Techies (Minefield Sign is not draftable)
* Meepo (Divided We Stand is not draftable)
* Rubick (Spellsteal is not draftable)
Will-o-wisp and Tag Team are now draftable in Ability Draft

* The Rubick Arcana Bundle now includes a Voice of the Magus Cypher item that lets Arcana owners choose whether to use the Arcana voice or the original Rubick voice. This item will appear in Arcana owners’ inventories shortly.

Removed Flowing Entropy from the Treasure of the Amaranth and instead included Enduring Solitude. Including the Flowing Entropy set was an oversight - Collector's Cache sets are intended to remain exclusive.

* New Bloom ended a few hours earlier than intended, the event has now been extended to be active through Feb 12th.
* Fixed an issue that caused the New Bloom Nian Courier to drop at lower than expected rates. This has been corrected, and items have been granted to reflect the proper drop rate.
* Fixed a bug that allowed pressing quickbuy in rapid succession to purchase the same item twice.
* Several Ranked Emoticons have been increased in size, and all emoticons used during in-game chat are now larger and closer to center on the chat line.
