A new patch is now available for Rainbow Six Siege, updating the tactical shooter to version 2.2. Included are some measures intended to combat cheating, including a ranked kill cam, and the new version also includes spawn kill countermeasures, matchmaking improvements, and bug fixes. All the details are in the Ubi Forums, and here's word on the anti-cheating stuff from the UbiBlog:

Rainbow Six Siege is about to become a harsher environment for cheaters because Patch 2.2 is bringing a new wave of fixes designed to deter cheats and exploits, with a special eye toward keeping players from being killed as they spawn. The biggest addition is a “Report” button players can use to flag behaviors they think are suspicious. To help eliminate any confusion about whether an opponent cheated, kill cams are being introduced to ranked matches, letting players see for themselves whether any foul play was involved in their deaths.

Also, tweaks are being made to multiple spawn points across eight maps, in some cases altering scenery to protect Attackers from being immediately killed by Defenders. For example, the Oregon map’s Construction Site now features added fencing and a higher, now-bulletproof wall to keep Defenders from firing on Attackers at the start of the match.
