Resolved strategy optimization exception
Resolved in Pega Version 8.5.3
After upgrade from v8.2 to v8.5, Customer Decision Hub strategy failures were seen in the data join used with a datapage/page list to fetch some results. Errors appeared in the logs and UI. The exception indicated that the Strategy Parser for the new execution engine (SSA) was not able to parse and inline the used expression. Normally this exception would be caught in subsequent processing and the component where the exception is used would fall back to legacy so as to not affect the runtime behavior, but this scenario triggered a corner case inside the parsing logic for Data Join and Exclusion shape which caused the exception and stopped the process. To work around this issue, the Data Join configuration can be split into two shapes: create a new Data Import shape to only import the Page list, e.g. 'Page.pxResults', then on the original Data Join component, instead of joining the 'Page.pxResults', join with the new Data Import shape. This issue has been resolved by catching the exception when compiling the Data Join component and properly falling back to the Data Join shape.

Unescaping characters implemented for expressions
Resolved in Pega Version 8.3.6, Resolved in Pega Version 8.4.4, Resolved in Pega Version 8.5.3, Resolved in Pega Version 8.6
An issue where expression builder statements were evaluated differently at runtime than at testing has been resolved. Pega Platform expressions with String literals(that is, sequences of characters enclosed in quotation marks) now unescape characters in strategy shapes such as Set Property or Filter.
