Here's the quickie reply -- I will put this up on the wiki in more
expanded form when I get more time.

When you login, you send an xml-rpc request to login.cgi, which contains
a bunch of parameters, including the version number in the form of
major/minor/patch/build.  We have added a new parameter called "channel"
which is an arbitrary string.  Also, we have compacted the four version
number parameters into a single string version.

Thus, the xml fragment would now be something like:
<member>
   <name>channel</name>
   <value>libsecondlife</value>
</member>
<member>
   <name>version</name>
   <value>1.15.0.2</value>
</member>

If we don't have an entry for the channel or version that you're
connecting with, it allows you to log in.  If you're logging in with the
 major/minor/patch/build specified individually, then it has to match
our existing versions (i.e. 1.15.0.2 -- this is how we're forcing all
old clients to upgrade).  So, just change to sending the version as a
string and it should let you in.
