Hi @Amna,
[…] keep the current version 10.5.2
Please note that with our 13.0 release all 10.x.y releases are out-of-support and -maintenance.
I’m curious about why exactly you want to stay on v10.5.2, but I definitely second @bartj’s advice to keep your instance updated, not just with regard to the patch levels, but also for minor and major releases.
Kind regards!
