<h1>Change Log</h1>
<h2>Next Version (unreleased)</h2>
<ul><li>MVCC: the probability of lock timeouts is now lower if multiple threads try to update the same rows.
<ul><li>H2 Console: opening a MS SQL Server database is now faster.
Also, listing the database meta data sometimes resulted in an exception.
</li><li>Linked tables / MS SQL Server: if the tables were created in mixed case in MS SQL Server,
then the identifiers in the linked tables were case sensitive (in H2).
</li><li>MVCC: the probability of lock timeouts is now lower if multiple threads try to update the same rows.
</li><li>Building only the documentation (without compiling all classes) didn't work, specially: ./build.sh clean javadocImpl.
</li><li>Documentation on how data is stored internally and how indexes work (in the performance section).
</li><li>Some people reported NullPointerException in FileObjectDiskMapped.
