Ubisoft has detailed their Rainbow Six Siege balance changes for Year 6 Season 2.2 in official Designer's Notes. This also includes the addition of the Favela map to ranked and unranked modes.

A lot of the operator changes were made due to R6‘s current ban rates, which were also detailed in the same post. One thing to note is that the Nokk rework will not be making it into Rainbow Six just yet. Despite being live in the test servers already, Ubisoft is still fine-tuning the balance. They said:

“Most recently, we tried removing the HEL Presence Reduction's ability to muffle sounds, but found players missed this noise reduction more than they liked the immunity to proximity detectors that replaced it. This makes sense, as muffled sounds have more universal utility, whereas proximity immunity's usefulness depends on the Defenders' team composition.

On top of this, we feel that players should always be able to trust their gadgets. By adding this experimental immunity to proximity detection, it made a wide range of additional utility feel unreliable, which we want to avoid.”
