General releases are stable and well-tested. They come with
an installer that will automatically set everything up and so can be installed
even by non-technical people.
They have 2 digits in their version number e.g. "1.1" or "2.3".
Beta releases are also stable and well-tested. They are
released as ZIP files so you must know how to unpack them using WinZip
(or a similar program). You may also need to do some additional tasks to complete
the installation e.g. run the Awasu Administration tool to upgrade your database
or copy some files around.
They have 3 digits in their version number e.g. "1.1.3" or "2.1.1".
