Really!?  That's great news...

Well, there are two major problems I've experienced.  The first is a 
trouble w/ VirtualHostBase, using an Apache/ProxyPass setup that works 
fine w/ several other 2.3.X and 2.4.X versions.  It involves an Apache 
VirtualHost resolving to a one-below-the-root folder in Zope which is 
authenticated via a LoginManager.  When I try it w/ 2.5.1, I get the 
login screen, but then, regardless of whether or not I authenticate 
correctly, I get a strange set of nested site errors.  There's one 
'NotFound' error, and in the place where the error's text message should 
be, there's ANOTHER site error that says 'Resource Not Found'.  And 
looking at the URL, I see that it looks like so:

https://www.blackrockcity.org/VirtualHostBase/https/www.blackrockcity.org:443/brc/VirtualHostRoot/

instead of merely "https://www.blackrockcity.org/".  Note that I can 
replace my 2.5.1 install w/ a 2.4.4 install that is identical in all 
other ways, and it will work.

The other problem I have is that a SkinScript that is in my UserSource 
can't seem to find a ZSQL method that lives directly above it.  I have a 
method called "SQL_findMember" in the LoginManager proper (i.e. the 
acl_users folder).  In the "member_storage" SkinScript that is in the 
UserSource, I have the following line:

WITH QUERY SQL_findMember(member_name=self.id) COMPUTE
     member_id, member_name, password, is_active, is_passwd_bad

When I try to authenticate, though, it is unsuccessful, and the 
STUPID_ZOPE_LOG shows the following error:

Any help resolving these issues would be HUGELY appreciated.  There's so 
little ZPatterns discussion anymore (and generally silence on the list 
whenever anyone asks about it) that I had just assumed it was a wash...
