Bug Fixes
Bug Fix Description

Platform Analytics Upgrade: RabbitMQ and Flink are reinstalled unnecessarily
Whenever Platform Analytics is upgraded, RabbitMQ and Flink are uninstalled and reinstalled regardless of version. This issue has been resolved by only reinstalling RabbitMQ and Flink if the supported versions have changed.
TA-3783
Property Transforms: Flink jobs are not recreated when the service restarts
In a Windows environment, when the Flink service is restarted after the Property Transform service, existing Flink jobs are not recreated. This issue has been resolved so that Flink jobs are recreated as expected.

Known Issues
Known Issue Description
Reference #
Property Transforms: RabbitMQ fails to start on a Windows server using a non-English locale
On a Windows server using a non-English locale, sometimes services like RabbitMQ, Flink, and Property Transforms fail to start after installation. The issue will be resolved in a future release by ensuring that the Platform Analytics installer registers the language-specific Network Service user name. Until then, a work around is available in article CS317399.
TA-4276
Platform Analytics Installation: Unsuccessful with specific RedHat/Erlang combination
Platform Analytics 9.0 cannot be installed successfully using Erlang/OTP 21.3 on RedHat Linux distribution 8.0. As a work around, use a different version of Erlang instead.
