# Release notes for OpsCenter

# Release Notes for OpsCenter 6.8.50
Due to numerous errors and customers reporting performance problems with the versions of OpsCenter released with the updated
java driver, we are going to release OpsCenter 6.8.51 with the driver update reverted as soon as possible. We will be removing
the OpsCenter versions with the driver issue and other significant issues from FixCentral. Those are 6.8.47, 6.8.48, 6.8.49,
and 6.8.50. We recommend customers encountering issues go back to 6.8.46 until a fixed version of OpsCenter is released. All
updates since 6.8.46 that are not related to the driver upgrade will remain in place.

        Released OpsCenter versions 6.8.48, 6.8.49, and 6.8.50 contain an updated Java driver that resulted in numerous errors and performance problems. A follow-on release, OpsCenter version 6.8.51, will revert the driver update.  Fix Central will no longer offer the prior release versions affected by this Java driver update, or version 6.8.47, pulled from Fix Central and fixed in version 6.8.48.  OpsCenter version 6.8.46 and earlier versions remain unaffected and are still available. All updates since version 6.8.46 that are not related to the driver upgrade remain in place.
      
      
        
        We recommend customers encountering issues temporarily revert to version 6.8.46 until the advent of version 6.8.51.


The OpsCenter team is making significant improvements to the QA process to avoid mistakes like this in the future.

* Fixed a regression introduced in the Java Driver 4.x migration where new-metrics requests took several minutes on large clusters. WrappedDriver.prepare() no longer issued a `PREPARE` command to Cassandra, resulting in every metrics query running unprepared and paying full parse + plan cost. Restored proper running of the prepared-statement, and closed a related CqlSession leak during coordinator reconnect. (OPSC-17887)
