What’s new with Oracle database 18.11 versus 18.12
This blogpost takes a look at the technical differences between Oracle database 18 RU 11 (july 2020) and RU 12 (october 2020). This gives technical specialists an idea of the differences, and gives them the ability to assess if the RU impacts anything.
Functions
code symbol names unique in version 18.11 versus 18.12 -- so removed functions in RU 12.

This is a poor, yet one of the only ways to understand what is going on inside the oracle executable.
There aren’t that many thing removed, which is understandable. Therefore I listed all the functions that were removed, not a as a grouped overview. The archive:object annotation is not there, I started doing that for the latest RU.
For the functions that were added, the vast majority comes from libjavavm18, and seem to be cryptographic related functions.
The only group that might show something is kewr (AWR), however I cannot see something in general that is changed, the names seem random:

Outside of code changes, there isn’t anything changed in the data dictionary.
