On May 1, 2022, Percona Monitoring and Management version 1 will enter the End of Life stage, which means it is not going to receive any security updates, bug fixes, and improvements.
Starting from April 2022, no new versions are going to be released for Percona Server for MongoDB 4.0 and Percona Distribution for MongoDB 4.0. New releases of Percona Distribution for MongoDB Operator and Percona Backup for MongoDB will not be tested against version 4.0 of MongoDB and corresponding Percona software.
Ubuntu Linux 16.04 has reached its end of life on April 30, 2021. We have decided to stop providing releases of our software for this platform in favor of focusing our efforts on more recent versions of Ubuntu.
