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.
Support for building apps as Android App Bundles
Valid from Pega Version 8.5.5
As of August 2021, Google Play Store requires that you submit new apps in the Android App Bundle publishing format instead of the APK format. You can now build Pega mobile apps in the Android App Bundle format so that they comply with this new requirement.
For more information about generating installation packages for Pega mobile apps, see Generating installation packages. For more information about the Android App Bundle publishing format, see the Android for Developers documentation.
