An update to Team Fortress 2 has been released. The update will be applied automatically when you restart Team Fortress 2. The major changes include:

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

* 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)

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.

An update has been released for Left 4 Dead.

- Dev command 'director_log_scavenge_items' can only be executed by the server. Reported via HackerOne.

* 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.

* Fixed an issue that caused players completing calibration games using Ranked Roles to not have the correct resulting calibrated MMR. Players who have already played calibration games with this behavior have have their MMR updated to reflect the correct values.
