Update Rollup 3 is the first UR post-transition to the new rollup servicing model. A very significant advantage of this model is the release predictability as we ship an update rollup every 8 weeks. The next rollup will release on May 7th. All the major product groups have moved to this rollup servicing model and many more are transitioning now as it’s been a win for Microsoft and our customers.
