<ul>
<li>Large updates and deletes are now supported by buffering data to disk if required. The threshold is currently set to 100'000 bytes and can be changed using SET MAX_OPERATION_MEMORY or using by appending ;MAX_OPERATION_MEMORY=.. to the database URL. See also the docs.

</li><li>Referential integrity checks didn't lock the referenced table, and thus could read uncommitted rows of other connections. In that way the referential constraints could get violated (except when using MVCC).
</li><li>Renaming or dropping a user with a schema, or removing the admin property of that user made the schema inaccessible after re-opening the database. Fixed.
</li><li>The H2 Console now also support the command line option -ifExists when started from the Server tool, but only when connecting to H2 databases.
</li><li>Duplicate column names were not detected when renaming columns. Fixed.

Version 1.0.62 (2007-11-25)
@changelog_1336_li
Large updates and deletes are now supported by buffering data to disk if required. The threshold is currently set to 100'000 bytes and can be changed using SET MAX_OPERATION_MEMORY or using by appending ;MAX_OPERATION_MEMORY=.. to the database URL. See also the docs.
@changelog_1337_li
MVCC: now an exception is thrown when an application tries to change the MVCC setting while the database is already open.
@changelog_1338_li
Referential integrity checks didn't lock the referenced table, and thus could read uncommitted rows of other connections. In that way the referential constraints could get violated (except when using MVCC).
@changelog_1339_li
Renaming or dropping a user with a schema, or removing the admin property of that user made the schema inaccessible after re-opening the database. Fixed.
@changelog_1340_li
The H2 Console now also support the command line option -ifExists when started from the Server tool, but only when connecting to H2 databases.
@changelog_1341_li
Duplicate column names were not detected when renaming columns. Fixed.

The console did not display multiple embedded spaces in text correctly. Fixed.

In the cluster mode, could not connect if only one server was running (last release only). Fixed.
@changelog_1346_li
The performance of large CSV operations has been improved.

Nested temporary views (SELECT * FROM (SELECT ...)) with parameters didn't work in some cases. Fixed.

CSV: Using an empty field delimiter didn't work (a workaround was using char(0)). Fixed.

The default value for h2.emergencySpaceInitial is now 256 KB (to speed up creating encrypted databases)

Eduardo Velasques has translated the H2 Console and the error messages to Brazilian Portuguese. Thanks a lot!

Creating a table from GROUP_CONCAT didn't work if the data was longer than 255 characters
