Data Social tag class FTS index query improvements
Resolved in Pega Version 8.5
A query intended to select from the link tag table to see if any cases were linked to the tag in question and then index the tag change was causing performance issues. Investigation showed that checking tag associations during FTS indexing fetched all matching rows from the table even though one was sufficient. To resolve this, the query will be created with max result count = 1, fetching up to 2 rows from the table.

Repaired Tracer use with Google Chrome
Resolved in Pega Version 8.5
After running Tracer while using Chrome, closing it and trying to run another resulted in an error indicating "Cannot Launch multiple tracer sessions for a requestor". This was identified as a bug with Google Chrome Versions greater than 70 and was caused by Chrome deprecating the use of sync XHR on page dismissal, and has been resolved by modifying the system to use a beacon API instead.

Thread context updated to supply steppage
Resolved in Pega Version 8.5
After upgrade, Server Startup was failing with the error "PEGA Rules Server not available". Investigation traced this to missing steppage information while invoking Rule-Utility-Function (from declare trigger when rule) during startup, which was caused by the thread calling the declare trigger, which was different from the thread running WhenRule, not being properly initialized during startup. To resolve this, the thread context has been changed to gThread, which contains the necessary steppage information.

PropertySet will iterate over changeList map copy to resolve CME
Resolved in Pega Version 8.5
An empty menu was seen intermittently when handling incoming email, and a ConcurrentModificationException error was logged. Investigation showed that a step scope changeList map used in the handleChaining method was sometimes modified by another process while the first one was iterating over it. To resolve this, PropertySet will receive copies of the change list map from clipboard pages instead of the original map.
