jTDS is the fastest JDBC driver for Microsoft SQL Server and Sybase. The 0.9 release is a complete rewrite from 0.8, a lot simpler and with fewer problems. It is the first major release after 3 months of work. In the meantime, jTDS has become fully compatible with JDBC 3.0 and it passes the JDBC Certification Test Suite.
Around 85 bugs were fixed and a lot of new features added:
o TDS 5.0 (Sybase 11 and 12) support
o TDS 8.0 (SQL Server 2000) support.
o Named pipes support.
o SQL Server 2005 support.
o Blob and Clob memory control.
o Control over preparing statement calls with the prepareSql property.
o Localized error messages support.
o Automatic protocol detection for all versions except 4.2.
