We have released a new early technical preview of the JDBC Driver for SQL Server which contains several additions and changes.

 

Precompiled binaries are available on GitHub and also on Maven Central.

 

Encrypt = strict

There is one breaking change in the 11.1 preview over previous releases. To support the new TDS 8.0 protocol where TLS encryption is negotiated before TDS, a new Encrypt option has been added, "strict". This required changing the getEncrypt() API to return a string instead of just a Boolean. Setting Encrypt to "strict" causes the driver to negotiate a TLS connection to the server first, instead of previous behavior where TDS was negotiated, then, if using encryption, TLS would be negotiated inside the TDS stream. Negotiating TLS first means all TDS connection and feature negotiation happens over an encrypted channel.
