PegaWAI ruleset deprecated in 8.5
Valid from Pega Version 8.5
Accessibility functions that were contained in the PegaWAI ruleset are now integrated into the main Pega Platform™. Consequently, the user interface in your applications now features accessibility functions out of the box, so you no longer need to use the PegaWAI ruleset to ensure accessible behavior in your application.

Default value of the threadpoolsize agent affects batch indexing
Valid from Pega Version 8.5.2
After you patch Pega Platform to version 8.5.2 or higher, the system changes the default value of the threadpoolsize agent, which controls the number of concurrent activities (threads) in the system, from 5 to 15. Batch indexing in Pega Platform™ does not require all 15 threads, so you can change the agent value to increase system performance by managing the indexing/distributed/batch/numworkers dynamic system setting.
If your deployment does not support that setting, and batch indexing does not use Queue Processors, the system uses the threadpoolsize value for batch indexing instead.
For more information, see Editing a dynamic system setting.
Tags disappear from Rich Text Editor source mode
Valid from Pega Version 8.5
When you use Rich Text Editor in HTML source mode, some tags disappear from the markup, which causes backward compatibility issues and data loss.
Cause
Pega Platform™ version 8.5.5 introduced the DOM Purifier security plugin. The plugin removes potentially vulnerable tags, including custom tags, from the raw HTML code in the Rich Text Editor source mode.
Workaround
You can disable the DOM Purifier plugin by adding the the window.disableDomPurifier = true
markup to the userWorkForm HTML fragment rule.
Alternatively, as of Pega Platform version 8.5.6, you can add a tag to the allow list by including the window.rteCustomAllowedTags = ['myCustomTag']
snippet in the userWorkForm HTML fragment rule.
In Pega Platform versions 8.5.6 to 8.6, the iframe
tag is added to the allow list by default.
