Data modifications (inserts, updates, and deletes) are now faster for existing tables because converting objects to byte arrays is avoided if possible.

It is now allowed to truncate a table if referential integrity has been disabled for this table or database.

The cache was not used efficiently when reading (behaving like a FIFO cache instead of an LRU cache).

The built-in profiling tool now uses a default stack depth of 32 elements and a default interval of 10 ms.

When killing the process after creating and dropping many tables (specially temporary tables), the database could not be opened sometimes.

Bugfix for the automatic db migration. IFEXISTS=TRUE should be removed from the "runscript" connection.

Bugfix for the automatic 1.1 db migration: only uppercase parameters where replaced. If a lowercase parameter like ifexists=true was in the connection url, the upgrade failed.

Problems with JDK 1.6.0_18 have been reports in the class StringUtils.quoteRemarkSQL. This method is now changed.

Support for null-safe equals. This includes the ANSI SQL standard syntax A IS [NOT] DISTINCT FROM B as well as the shorter A IS [NOT] B.

  classes (v 1.2.128) connect to the database. The automatic upgrade .jar file must be present, and the url
  must contain NO_UPGRADE=TRUE
