For the first time this year Microsoft has bucked its trend of releasing one update per month for its Xbox consoles. The newest update (OS version: 10.2.22000.4558) released on May 10 for Xbox One and Xbox Series X|S, less than a week following the usual monthly update that released on May 4.
According to the patch notes section, the update features "General stability and performance improvements" that are otherwise unspecified. One has to wonder if the new update has anything to do with the recent Xbox Network outage that occurred over the weekend, though as stated no real details have been given on what actual fixes and improvements the second May update brings.
Users can install the update manually by pressing the Xbox button, then navigating to Profile & system > Settings > System > Updates. On the Updates page you will be able to see available updates that have yet to be installed, and opt to install them now.
