Resolved Cassandra query read/write latency
Resolved in Pega Version 8.2.8
Read/write latency was seen when certain Cassandra queries were triggered by the system. This was traced to an unusual case where a flush was not done for an exceptionally long time period, and has been resolved.

Support added for expression in strategy scorecards
Resolved in Pega Version 8.2.8
When invoking REST against a dataflow that had a strategy containing a scorecard that used an expression and the "Include model explanations option" was enabled in the Strategy configuration, the system failed with the error "PropertyValueInvalid .pxMaxScore Cannot cast the value (unknown) to double". This was traced to the Scorecard explanations failing during serialization when an expression was used, and has been corrected.

Oracle database performance improvements
Resolved in Pega Version 8.2.8
When the IH Summary was enabled and materialized on an ADM model, updating the ADM model was very slow on large sites. This has been resolved by adding several performance improvements for working with Oracle databases, including Oracle pre/post processing steps.

Handling added for Oracle Aggregate IH Summaries
Resolved in Pega Version 8.2.8
When using using (Non Materialized) IH Summaries to aggregate IH data, the data returned by the IH summary did not include all the expected records. If the same criteria was executed on the database via SQL or by using a strategy to process raw IH data then the results were as expected. This was due to a difference in handling of Oracle vs postgres which causes an order by clause not to be generated in the query: the postgres column name is lower case, while in Oracle it is upper case. This has been resolved by updating the system to get the column name correctly from the propertytocolumn map so IH records are returned in correct order by Browse By Keys operation.

Data Flow correctly saved to Database table Dataset
Resolved in Pega Version 8.2.8
After setting up a dataflow with Report definition as a source and Database table dataset as destination with the option "Insert new records and override existing", a data transform was used to modify a few of the values and write to the same database table. This table was mapped to pegadata schema and didn't have a pzpvstream column. Running the data transform generated an exception stating "DataStoreSaveStatementWithoutStream(PageDatabaseMapperImpl). The error was not seen when the pzpvstream column was added or if pzInskey was also removed along with pzpvstream, or if "only insert new records" was selected. This was traced to pzInsKey and pxInsName being null in the query formed while writing. There are two execution paths for the database dataset save operation, one for internal tables and another one for external tables. For a table with pzInskey but no blob, the system was incorrectly using the external table logic. This has been corrected.

Mentioned user in Pulse correctly converted to hyperlink
Resolved in Pega Version 8.3.3
In the Interaction portal, mentioning a user in Pulse using @ was not converting the name to the user name with hyperlink for Email Interactions. @ mentions were working as as expected in Phone Interactions. This problem was introduced as part of using OWASP to sanitize HTML user input in Rich Text support, and was due to OWASP converting @ to an HTML entity. To resolve this, the @ will be excepted from HTML conversion.

Optional feature to improve pxETReport performance
Resolved in Pega Version 8.3.3
Poor performance was seen when using pxETReport. This was caused by the system loading the recent cases widget by looking up all the ET cases within last 30 days, opening each ET case to check if it is from the same pyFrom email address, and then if yes, opening its related service case. On a complex system, this was potentially a slow process. To improve performance, the "Related cases" feature can now be disabled through an overridable 'when' rule.

Performance improvements for opening cases with embedded images
Resolved in Pega Version 8.3.3
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.

Webchat bot interaction box cleared on submit
Resolved in Pega Version 8.3.3
After upgrade, when using Google Chrome responses to webchat bot questions were not getting cleared from the chat input window after the enter/send button was clicked. This has been resolved by changing the order of refresh section and set value and disabling submit on refresh when refreshing pzSubmitArea.

Webchat interaction timeout updated
Resolved in Pega Version 8.3.3
Interaction timeout was not working as expected in Webchat channels. This was traced to the system looking for total interaction timeout instead of user inactive timeout, along with the Web chat interaction case clipboard page being stale. To resolve this, timestamp propagation has been updated for pxProcess in Work-Channel-Interaction.pxAcquireInteraction.
