<b>Changes and new functionality:</b>
<ul>
<li>The cache size is now measured in blocks and no longer in rows.
Manually setting the cache size is no longer necessary in most cases.
<li>CREATE VIEW now supports a column list: CREATE VIEW TEST_V(A, B) AS ...
<li>New column IS_GENERATED in the metadata tables SEQUENCES and INDEXES.
<li>ResultSetMetaData.isNullable is now implemented.
<li>Optimization: data conversion of constants was not optimized.
<li>Optimization: deterministic subqueries are evaluated only once.
<li>Compatibility: ''T'', ''Y'', ''YES'', ''F'', ''N'', ''NO'' (case insensitive) can now also be converted to boolean.
<li>Compatibility: SUBSTRING(string FROM start FOR length).
<li>Compatibility: TRIM(whitespace FROM string).
<li>LIKE ... ESCAPE: The escape character may now also be an expression.
<li>IF EXISTS / IF NOT EXISTS implemented for the remaining CREATE / DROP statements.
<li>An exception was thrown if a scalar subquery returned no rows. Now NULL is returned.
<li>Objects of unknown type are no longer serialized to a byte array.
<li>Reduced jar file size: The regression tests are no longer included in the jar file.

<b>Bugfixes:</b>
<ul>
<li>Issue #123: The connection to the server is lost if an abnormal exception occurs.
<li>Issue #124: Adding a column didn''t work when the table contains a referential integrity check.
<li>Issue #125: Foreign key constraints of local temporary tables are not dropped when the table is dropped.
<li>Issue #126: It is possible to create multiple primary keys for the same table.
<li>A few bugs in the CSV tool have been fixed.

<br>
<b>Changes and new functionality:</b>
<ul>
<li>Reduced memory usage: implemented a String cache and improved the Value cache.
Now uses a weak reference to avoid OutOfMemory.
(however the row cache could still cause OutOfMemory).
<li>New functions: MEMORY_FREE() and MEMORY_USED().
<li>Newsfeed sample application (used to create the newsfeed and newsletter).
<li>Server: changed the public API to allow an application to deal easier with start problems.
</ul>
<b>Bugfixes:</b>
<ul>
<li>Issue #116: Server: reduces memory usage. Reduced number of cached objects per connection.
<li>Issue #117: Server.start...Server sometimes returned before the server was started. Solved.
<li>Issue #118: ALTER TABLE RENAME COLUMN didn''t work correctly.
<li>Issue #119: If a table with autoincrement column is created in another schema,
it was not possible to connect to the database again.
<li>Issue #120: Some ALTER TABLE statements didn''t work when the table was in another than the main schema. Fixed.
<li>Issue #121: Using a quoted table or alias name in front of a column name (SELECT "TEST".ID FROM TEST) didn''t work.
<li>Database names are no longer case sensitive for the Windows operating system,
because there the files names are not case sensitive.
<li>Issue #122: Using OFFSET in big result sets (disk buffered result sets) did not work. Fixed.
<li>Outer joins did not always use an index even if this was possible.
</ul>
