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.
We have been maintaining 4.10 as our current ESR. This version is coming to the end of its lifecycle and we will be implementing version 5.9 as a new ESR. Starting 7/15/2019 we will no longer be backporting fixes to 4.10. Please upgrade your systems to 5.9 l as soon as possible to continue to receive important bug and security updates.
