Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.2.8
A Rules upgrade failed in the Migration step at loadDatabase stage, involving the move of all the table records from old schema to new schema. This was traced to the inability of Migration to load blob of sizes more than 100 MB, and has been resolved by updating Migration to use byte[] to read the blob content with the help of metadata that contains blob length.

TableRenameUtil hashing improved

Simplified default reference time calculations
Resolved in Pega Version 8.6.4
After a job scheduler was configured to run at Start time = 21:00:00 for Time zone = Europe/London, the scheduler determined 20:00:00 as the next start time. This was due to the calculation for the next start time using the time zone offset calculation pattern for the date and time stored in System-Runtime-Context.pxCreateDateTime, which had difficulty with changes to the time zone definition implemented in the time between the given date and today (meaning the current time) such as daylight savings time. To resolve this, the default reference time from System Runtime Context will be 'now' instead of Date(0).

TextMask_Encrypted rule added for use with Oracle
Resolved in Pega Version 8.6.4
When a property was being encrypted by propertyEncrypt access control policy and masked by propertyRead access control policy, it showed a "@@getMaskedValueOfText" error. This has been resolved with the addition of a new rule pxTextMask_Encrypted for Oracle product type which will remove extra spaces from the SOURCE string to handle ORACLE specific usecases.

Delay Factor updated to allow values < 1.0
Resolved in Pega Version 8.6.4
After modifying the "Delay factor" parameter on a queue processor rule and and clicking the "Save" button, refreshing the page caused the value of the "Delay factor" parameter to change. This has been resolved by updating the delay calculation strategy to support factors < 1.0.

Enhancements added for external Kafka Stream Service
Resolved in Pega Version 8.6.4
To ensure data privacy when using multi-tenant Stream Service hosted on a single Kafka cluster, access will be authorized based on ACLs when a tenant sends direct requests to Kafka. In addition, all Kafka resources (topics and consumer groups) are now able to contain a prefix naming convention which can be used for tenants. This is handled through using a <env name="services/stream/name/pattern" value="{tenant.name}-{environment}-{stream.name}"/> prconfig setting to set the stream name pattern. For example, if the tenant.name is resolved into "companyname", environment into "prod1", and the stream dataset name is pyFTSIncrementalIndexer, then the Topic name created on the external Kafka will be companyname-prod1-pyFTSIncrementalIndexer.

Handling added for external Kafka authorization exception
Resolved in Pega Version 8.6.4
When using external Kafka for stream service, the dataflow was failing with the error 'QueueProcessorDataSubscriberException' when topic create permission was missing. As a workaround, the topics could be pre-created, though a "Topic already exists" warning was generated. To resolve this, the cluster-wide right that a producer needs, IdempotentWrite, has been added.
