The seasonal updates are always the largest, and bring the greatest changes, especially compared to the Year 5 Season 4.3 patch. Ubisoft has diligently compiled a list of the changes in a set of patch notes. As always, a new Rainbow Six Siege season brings a rank reset, requiring players to play ten placement matches.

Big changes continue to come to the long-running game for Crimson Heist, including a new way of unlocking operators, continued release of reworked maps, and brand new items.

Ubisoft's Rainbow Six Siegeis gearing up to enter its sixth year of content, beginning with Operation Crimson Heist. The Year 6 Season 1 update is already on the test server and fully releases next month.
