&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;It is unbelievable! We are approaching &lt;br /&gt;
[[APIFest08:Task4|task4]] of [[APIFest08]] and we still have eight participants who play with us! Moreover the competition is still not decided, as far as I can tell. Today I spent few hours looking for [[BackwardCompatibility]] problems and I still have not managed to break three solutions! It is not that surprising as some of the competitors follow advices of [[TheAPIBook]]. For example I've seen [[APIDesignPatterns:ResponseReply]] being used. Good.

&lt;br /&gt;
That is why let me ask call [[APIFest08:Task4|round4]]: Please integrate with dates. Keep history of conversions, allow queries in historical data, etc. Please see [http://source.apidesign.org/hg/apifest08/rev/a92eff6b426f Task4Test.java] with the actual quests.&lt;br /&gt;
&lt;br /&gt;
Locate your solution among existing [http://source.apidesign.org/hg/apifest08/file/tip/task4/ task4] directory. There shall already be  [http://source.apidesign.org/hg/apifest08/rev/a92eff6b426f Task4Test.java] file along your '''Task1Test.java''', '''Task2Test.java''' and '''Task3Test.java'''. Enhance your API, show its usage in the '''Task4Test.java'''.&lt;br /&gt;
&lt;br /&gt;
After you are done, please generate a diff. The best way is to use [[Mercurial]]:&lt;br /&gt;
&amp;lt;source lang=&amp;quot;bash&amp;quot;&amp;gt;&lt;br /&gt;
# create the repository&lt;br /&gt;
hg clone http://source.apidesign.org/hg/apifest08/&lt;br /&gt;
# or update it&lt;br /&gt;
hg pull; hg update&lt;br /&gt;
# then do your modifications&lt;br /&gt;
# ...&lt;br /&gt;
# do not forget to add newly created files&lt;br /&gt;
hg add task4/solutionXY&lt;br /&gt;
# and finally produce a diff&lt;br /&gt;
hg diff&lt;br /&gt;
&amp;lt;/source&amp;gt;&lt;br /&gt;
you can obtain the diff in other ways, potentially you can send us to [mailto:apifest08@apidesign.org our mailing list] the whole ZIP file, but diffs are preferred.&lt;br /&gt;
&lt;br /&gt;
Please submit your solutions by '''Thu, Oct 16, 2008, morning of CET'''. I guess this is the last coding round. On Saturday you will start hacking solutions provided by others!&lt;/div&gt;</description>
