Password hash: in addition to connecting with the plain text password, H2 now supports connecting with the password hash.

The built-in connection pool (JdbcConnectionPool) did not always honor the login timeout (the timeout could occur much too early).

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).
