Extended Support Release Updates

We are implementing version v5.25 as a new Extended Support Release, which will be released on July 16, 2020. v5.25 will be supported until April 15, 2021.

We have been maintaining v5.19 as our current ESR. This version is coming to the end of its lifecycle later this year. Starting October 15, 2020 we will no longer be backporting fixes to v5.19. Please upgrade your systems to v5.25 as soon as possible after it is released to continue to receive important bug fixes and security updates.

Extended Support Releases or ESRs are intended for organizations who value stability over having the newest features and improvements, or for organizations who have a long internal testing and certification process to undergo when upgrading.
