Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.2.8
A Rules upgrade failed in the Migration step at loadDatabase stage, involving the move of all the table records from old schema to new schema. This was traced to the inability of Migration to load blob of sizes more than 100 MB, and has been resolved by updating Migration to use byte[] to read the blob content with the help of metadata that contains blob length.

TableRenameUtil hashing improved

Deployment Manager rollback works for directed inheritance
Resolved in Pega Version 8.6
Rollback was not working correctly in Deployment Manager for history classes using directed inheritance. This was traced to a redundant check in AbstractHistoryPageKeeper that enforced the history pages pattern inherited from one of the base history classes, and this has now been removed.

Improved handling to ensure circumstanced rules skim is complete
Resolved in Pega Version 8.6
After performing a major rule skim, it was noticed that some of the circumstanced rules were not carried over to the higher version. The data was restored and a second skim was attempted. Once again, not all of the circumstanced rules were carried over; however, the results were different than in skim 1. This issue was traced to the circumstanced rule and base rule having the same pxCreateDateTime because they were processed with in a millisecond span. To resolve this, a 1ms explicit sleep has been added before processing each record.

Changelog cleanup added for de-optimized properties
Resolved in Pega Version 8.6
Unwanted optimization was automatically added to properties for the Application-Work-Casetype class created using the wizard in the App Studio. Attempts to remove the optimization did not work: the property advance tab was showing the optimized classes details even after deleting and recreating the property. When a property is optimized the system adds entries to pr_changelog for the list of classes it has optimized. When the property was deleted, the pr_changelog was not cleared. This was a missed usecase, and has been resolved by overriding the Cleanup activity at Rule-Obj-Property class to delete the pr_changelog entry associated with that if it is present.

Unneeded AUC error percentage calculation removed for better system performance
Resolved in Pega Version 8.6
When generating snapshots of the ADM models, an inefficiency in the metric calculation for the AUC error percentage caused an excessive amount of memory to be allocated which could cause slowdown or require a system reboot. This has been resolved by removing the problematic AUC error percentage calculation as it is not used in the UI.
