This changelog is the comprehensive history of Parsec's product changes. Some of the features listed have been deprecated or were changed in later updates. We thought, rather than changing old posts, it would be fun for everyone to see the whole history of the product's development. For a perspective on Parsec's product and our product philosophy, we wrote a blog post in December 2017 about the early history of the Parsec Game Streaming software.

SCHEDULED MAINTENANCE
[Teams] Quarterly Maintenance Window — We will be performing routine scheduled maintenance on Saturday, September 5th, 07:00 am - 11:00 am EDT. During the maintenance window, we'll be upgrading parts of our infrastructure to newer versions. You may experience brief moments of unavailability when attempting to establish a session or finding your hosts during this window. If you need to use Parsec during this time, we recommend establishing a session prior to the beginning of the maintenance window, as existing connections shouldn't be impacted. For real-time status updates about Parsec, you can subscribe to receive notifications at https://status.unity.com. More info.
