There are some impressive new features in 20.2. unfortunately my latest upgrades are not going so well.
I see we've got a bundle patch already! Patch 32006852: PSE BUNDLE FOR APEX 20.2 (PSES ON TOP OF 20.2.0.00.20)... But I don't see any of the issues I encountered being addressed.
From most to least severe:
1) ORDS 19.1 munged 3 times over 3 installs
