Enhancements for upgrading in multi-tenant environment
Resolved in Pega Version 8.1.9
Some muti-tenant installations use the same applications or rule instances with the same pzInsKeys for different tenants. This can cause upgrades to time out due to the system fetching all pzInsKeys (which will have duplicates) and working with them in a default batch size of 500 each over 4 threads. This led to the same keys potentially being allocated and processed in different threads, resulting in duplicate processing and timeouts. This has been resolved by updating the select query to fetch the tentantid and pzInskeys in the MT system to avoid duplicate work in multiple threads. In addition, running Generate Declarative indexes fetches the pzinskeys and generates indexes for each record, but before generating, the existing index for the record is deleted and then inserted. Because the delete query to generate the index was not tenant aware, all of the records for the key were deleted for the tenants for that key, but the new index was created only in one tenant. This has been resolved by enhancing the DELETE query to be tenant aware, which will avoid deleting the indexes for all the tenants given an index key.

Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.1.9
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
Resolved in Pega Version 8.1.9
During index name generation, the algorithm that was responsible for index name uniqueness was sometimes insufficient and cerated a loop condition. This has been resolved by using a stronger hash algorithm and refactoring the code that could result in a loop.

Check for circular references added to SearchInventoryImpl to prevent recursive call
Resolved in Pega Version 8.1.9
An out of memory error was traced to SearchInventoryImpl infinitely recursing over a clipboard property, where the child property referenced a parent property and resulted in an endless loop. This has been resolved with the addition of a depth check to ensure that the search does not recurse infinitely.

Embedded Pega Chat error resolved
Resolved in Pega Version 8.2.6
A cross-origin frame error was shown when the Pega Chat Window was embedded in a non-Pega page. Investigation traced the issue to code that was accessing the top/parent window, and which failed when used in a mashup scenario. This has been resolved with a try/catch block to wrap the code and handle scenarios where the

Added property check for outbound templated email reply
Resolved in Pega Version 8.2.6
When a template was used for the first time for outbound correspondence, email was generated correctly. If the same template was used as the content for reply, the generated email skipped all styles. This was traced to a missing property check, and has been resolved.

Performance improvements for opening cases with embedded images
Resolved in Pega Version 8.2.6
Opening cases containing email interactions was taking an excessive amount of time. This was traced to the use of embedded images, icons, etc, in the message body and signature, and was caused by the pyGetAttachmentsbyCID activity running multiple times due to discussion threads that were duplicated over and over. In some cases, more than 360 calls to the database were seen. This has been resolved by shifting some case opening processes to executing when the listener thread gets the mail, and storing the results in a .pynote property, and a URL will be used to get images instead of embedding them directly to the HTML. If preferred, this can be reverted to the previous behavior by changing the when rule (pyUseCachedHtmlForDisplay) to false.

Run Ruleset Cleanup defaults to true
Resolved in Pega Version 8.2.6
After upgrade, the rule categories and rules were not showing correctly in the App view of the Dev Portal. Many warning messages were also logged related to the Decisioning DM Sample application. This was traced to the rules cleanup script not running properly. While there was a workaround of applying the ruleset cleanup scripts manually after removing the queries that reference the pr_engineclasses table, the cleanup will now be set to run by default (run.ruleset.cleanup=true). In addition, the logic to determine which RuleSets to include has been simplified and most of the pr4_rule_vw deletions have been combined.
