Update 50 is available on a public test server, with various outlets reporting its availability for different applications, including games such as Fallout 76, Elder Scrolls Online, and possibly Diablo IV. The update's content and purpose are unclear, as different sources mention different features, including a new overland challenge difficulty system and a test of the "Prince of Madness". The term "Update 50" may also be unrelated to gaming, as it appears in reports on influenza surveillance and other topics.
