As previously mentioned, we decided to skip MPS 2022.1 as we were too busy fixing issues from the last release and didn’t have enough time to prepare the new functionality. Now we have new features to present to give you a glimpse of what’s to come in MPS 2022.2. DOWNLOAD MPS 2022.2 EAP Annotations in Inspector Annotations are now accessible from the Inspector window, and the annotation process will start for the entire root.

MPS Is Skipping the 2022.1 Release

MPS 2022.1 was supposed to be released this month, but we unfortunately have to announce that this is not going to happen. The previous release, MPS 2021.3, was released late, which gave us a shorter time frame for fixing the bugs of the new features, while also developing functionality for MPS 2022.1. Rather than risk falling into a cycle of rushes and delays, we have decided to skip the release of MPS 2022.1 and start working directly on MPS 2022.2, which is scheduled to be released in the third quarter of this year. We are sorry for any inconvenience that this may cause. Your JetBrain
