+<b>Q. What is an Alpha Release?</b><br/>
<div class="txt">
Typically when software is created at a software company, it goes through a number of stages
before it's released out to the world. You've probably heard of 'beta-testing' before. That's
when people take code that has been deemed 'not quite ready' and are testing it out so that
the authors can fix bugs where necessary.
-<br>
+<br/>
'Alpha' code usually is strictly for internal development only, which is to say, 'No one sees this code,
it's not even close to being done yet.' At the Xiph.org Foundation, we release everything we do
so that people can help us move the codebase forward by reporting bugs and submitting patches.
-<br>
+<br/>
We encourage and depend on the open-source developer community to get
involved early. We release Alpha builds to give people a chance
to see what's cooking, and perhaps to add some ingredients of their own. If
you think you have the right stuff, please join the party at
<a href="/discussion/">www.Theora.org/discussion/</a>.

Tarkin is essentially a proof-of-concept wavelet-based codec. Its

Xiph.org will be focusing its efforts on Theora for the near future.
