In current NetOps 20.2 Performance Monitoring documentation there are no "Fixed Issues" listed in the related section:
Currently the 'Fixed Issues' list for this version is under review and consolidation.
Release : 20.2

At the time of writing this article, the 'Fixed Issues' list for this version is under review by Engineering.
It will be added to the documentation when officially ready.
The current NetOps 20.2 GA version (20.2.1) should include almost all the fixes included in CA Performance Management 3.7.12
Fixes are always cumulative between various CA PM 3.7.x versions.
