Enhancement added for node heartbeat recovery process
Resolved in Pega Version 8.3.5
Nodes were not showing up in the admin portal even though they were up and running and could be seen in the pr_sys_statusnodes table. The exception "An exception was encountered while invoking the cluster membership listener callback" was seen. All nodes became visible again after multiple restarts. The root cause was traced back to a temporary database connectivity problem. The database itself was fine according to database monitoring reports, but a network problem, a slow database query, or another issue prevented Pega from establishing a connection for more than a minute. An enhancement has been made to resolve this: if a node becomes unhealthy due to the service registry missing due to a failed heartbeat, the heartbeat will try to recover after 60 seconds and keep trying every 30 seconds until it succeeds.

Resolved Cassandra query read/write latency
Resolved in Pega Version 8.3.5
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.

Handling added for clearing node killed between assignment and processing
Resolved in Pega Version 8.6.3
An Offer flow was not resuming after it expired according to the wait shape. Investigation traced this to partitions which were assigned to a dead node in NEW state where they were not picked up by the dataflow. The problem was only encountered in the unusual situation when a dataflow node was killed in the brief period of time between the assignment and the processing, and has been resolved by adding an update which will clear unknown new assigned partitions for the batch run health task.

Localization added to DelegateDescription
Resolved in Pega Version 8.6.3
Localization was not working correctly for the description of a delegated rule due to pyDelegeteDescription being defined with a non-localized Property value. This has been resolved by localizing the property value for pyDelegeteDescription.

Updated entity attachment extraction tokenizers
Resolved in Pega Version 8.6.3
After creating an entity extraction model, it was seen that one of the entities worked when there was a space after the semicolon but the detection was not working if there was no space. This has been resolved by updating the Tokenizers with extra examples to address tokenization when ":" is present between two words without any spaces.

Resolved error for custom relative dates
Resolved in Pega Version 8.6.3
An error was seen when parsing the [Date Property] [is before/after] [Last/Next x days] while using a custom amount of number of days in Customer Decision Hub (CDH). This was due to the system not supporting the [Last/Next x days] feature for SSA, but only detecting this during parsing for the prefixed values for Proposition Filters and not custom values. As the parser did not realize the construct referring to the relative date was not supported, it created an SSA that caused an exception during execution. This has been resolved.

Actuals sync clears data from cache and persistence
Resolved in Pega Version 8.6.3
When sync attempted to clear the existing data from Actuals before copying data from the interaction history, the partition was cleared from the cache but not from persistence. IH data that was then copied to the same partition time ranges had new field descriptors created that did not match the format of the old data in persistence. As a result, when a query triggered the loading of such a partition, the mix of data with the old and new formats caused the load to fail. This has been resolved by updating the system to ensure the data is deleted properly from both the cache and persistence.

Resolved in Pega Version 8.6.3
