Changes (as compared to 8.4 beta2) include:
* Added an option to find redundant indexes. The control and the information is available from INFO tab/html view. Please refer documentation for details. This is an ULTIMATE feature.
* Stabilized new features added in previous 8.4 betas.
* Fixed a crash (reported internally) that could happen when sorting on multiple columns in DATA tab. Also an invalid query could be generated under same conditions.
* Notifications services would not execute queries after a query returning an error if connection was over a HTTP-tunnel even if user had selected not to abort on error.
