Next Version (unreleased)
</h2>
<ul><li>
The SQL statement "shutdown defag" could corrupt the database if the process was killed
<ul><li>
Database URLs can now be re-mapped to another URL using the system property
"h2.urlMap", which points to a properties file with database URL mappings.
</li><li>
When using InputStream.skip, trying to read past the end of a BLOB failed with
the exception "IO Exception: Missing lob entry: ..." [90028-...].
</li><li>
The in-memory file system "memFS:" now has limitted support for directories.
</li><li>
To test recovery, append ;RECOVER_TEST=64 to the database URL.
This will simulate an application call after each 64 writes to the database file.
A log file databaseName.h2.db.log is created that lists the operations.
The recovery is tested using an in-memory file system, that means it may require a larger heap setting.
</li><li>
Converting a hex string to a byte array is now faster.
</li><li>
The SQL statement "shutdown defag" could corrupt the database if the process was killed
while the shutdown was in progress. The same problem could occur when the database
setting "defrag_always" was used.
</li></ul>
