The wrong error message was thrown when trying to open a database where the database file could not be read for some reason (for example because the split file system was used, and the file was split at the wrong position).

The scan-resistant cache type "TQ" (two queue) is again available. To use it, append ;CACHE_TYPE=TQ to the database URL.

Opening a database with a corrupt split file must lead to a database exception, not a "Database may be already in use" exception

There was a memory leak in the trace system. Opening and closing many connections could run out of memory.

Server tool: the tcpShutdown feature now also stops other servers (web server and PostgreSQL server).

Lob in database: after the process was killed while adding a lob, inserting a lob could throw an exception (primary key violation in LOB_MAP).

Multi-version concurrency: SELECT ... FOR UPDATE threw a "concurrent update" exception immediately instead of a "lock timeout" exception after the set lock timeout if the row was already locked by another connection.

Translation: the H2 Console and error messages have been translated to Czech by Hannibal (http://hannibal.cestiny.cz/). Thanks a lot!

When the system property h2.lobInDatabase is set, reading a BLOB is a bit faster because the length is not read.

Cache size limit could be exceeded for certain queries, leading to an OutOfMemoryError in some cases.

Issue 269: GROUP BY queries with a column or having clause that contains IN(SELECT ...) could return the wrong values. Example: SELECT X IN(SELECT Y) FROM Z GROUP BY X.
