Access to system tables is now more restrictive for non-admin users (the tables can be still listed and read, but some of the data is not included).

The default expression of a column may no longer reference the table, because a database with such a table couldn't be opened normally.

Referenced objects in check constraints could be dropped, which resulted in a database that can't be opened normally.

The auto-server mode can't be combined with an in-memory database. This invalid combination wasn't detected so far. Now trying to open a database in this way fails.

Java functions: array component types are now preserved, so that a ResultSet.getObject() will return Integer[] if the Java functions returns Integer[]. Thanks to Noel Grandin for the patch.

Recover tool: the script generated by the recover tool didn't work if fulltext search was used, because the triggers were created before the primary keys.

Read-only databases: some queries (such as distinct queries) tried to create temporary tables, which failed for read only databases.
