A hotfix released with some solutions in it. But there is an important, serious problem in memory leak. UE-23794, UE-23795, UE-24035… I don’t know maybe there are even much more jira subject related to this issue. Let me remind what the problem is; there is a unstoppable leak in memory, starts with 700 mb, just after opening some blueprints, in 15 minutes memory usage of ue4 editor reaches to 13-14 gb (of 16 gb). That should have the highest priority, because every 15 minutes, editor needs a restart.
