Data Virtuality Platform 3.0.5 (beta): Kerberos support and other improvements

This release is almost exclusively about the Server, and brings one new feature, two improvements, and a number of bug fixes. As part of two of them, we've had to modify our JDBC driver, so we ask you to update the JDBC drivers used by third-party clients accordingly.

The new feature is the support of the Kerberos authentication protocol - now you can use it with your Data Virtuality Server instance. We've also prepared dedicated documentation with detailed information on pre-requisites and guides on how to configure your Data Virtuality Server instance, JDBC clients, and ODBC clients.

Speaking of improvements, these are small, but they'll make working with the Server more smooth. In the first improvement, we've improved punctuation in error messages making them easier to read. The second improvement extends logging for the ALTER VIEW command making it more useful for testing and debugging.

As for the bug fixes, most importantly, we've fixed the bug with the Excel connector causing incorrect results to be returned if the "allColumnsAsString" property is set to FALSE and a column contains values of different data types. We've also fixed another bug affecting the same connector and causing TIME and DATE cells to be converted to TIMESTAMP in some cases - now they're correctly mapped to TIME and DATE.

We've also fixed a bug occurring during the creation of materialization and replication jobs via the Studio: previously, they would fail with a NullPointerException if the user didn't have permissions for the relevant SYSADMIN procedures. Now, you'll see an informative error message with the name of the procedure so you'll know immediately what's missing and what to do about it.

As for the Connectors, we've worked on improving our Amazon Selling Partner connector and would like to take this opportunity to thank our amazing customers for their suggestions - we're always glad to hear your feedback!
