<p><% name %> version 1.0 released on 11/29/08</p>

<a id="NewFeatures"></a><h2>New Features</h2>

<ul>

<li>Given an attribute of type list with the name "bars", MK will now

not only generate a Python method <code>addToBars()</code> for adding

objects to the list, but also a method named <code>delFromBars()</code>

that will make it easy for you to remove an existing object from the list

(as suggested by Luke Holden in patch #670051).</li>

<li>The SQLObjectStore method <code>executeSQL()</code> now can commit

the SQL statement immediately if you pass in <code>commit=True</code>.

This is helpful since the standard DB API <code>execute()</code> method

does not commit automatically, and MySQLdb now follows the standard.</li>

<li>A method <code>executeSQLTransaction()</code> has been added that

executes and commits a sequence of SQL statements as a transaction.</li>

<li>The MySQLObjectStore can now be created with a keyword parameter named

<code>autocommit</code> that will reestablish the old behavior of MySQLdb

of auto commiting every statement if you set to True. But note that by

default there will now be no autocommit any more.</li>

</ul>

<a id="Improvements"></a><h2>Improvements and Refinements</h2>

<ul>

<li>Added a lock for accessing the MiddleKit persistent store to avoid

race conditions with multithreading (as suggested by Roger Haase).</li>

<li>Do not allow attributes with some reserved names because they can

lead to confusing error messages later (bug report #925481).</li>

</ul>

<a id="MinorChanges"></a><h2>Minor Changes</h2>

<ul>

<li>The PostgreSQL SQL generator now generates DateTime attributes as

timestamps <em>without</em> time zone. This is also the default in newer

PostgreSQL versions and in MySQL. It is recommended to simply store all

DateTimes as UTC.</li>

</ul>
