Yes, it is official.  We tried our best to make sure the code itself  
was in a good-enough shape that we could get it out in the wild as  
something that can be considered stable and untouched until the next  
release.  We knew there would be some documentation issues cropping  
up and that we would fix them ASAP.

FYI, the current plan is to make a release once a month, and to keep  
the API as stable as possible now until the 3.0 final release.  Since  
we're using branches and tickets now, each monthly release will have  
a changelog that lists all of the changes since the last version, and  
whether or not the user of Schevo will need to do anything different.

Now that we have made the 3.0b2 release, I'd suggest using the  
monthly releases instead of trunk releases from now on, so that it's  
easier for you to keep a stable system in place and know details  
ahead of time when you decide to upgrade to newer versions.

SchevoQt must be licensed under the GNU GPL (because Qt and PyQt  
themselves are GPL), instead of the GNU LGPL as with the rest of  
Schevo.  Also, since new navigator developments are occurring in  
SchevoGtk (which is LGPL) and no new developments are occuring in  
SchevoQt, we did not make an official announcement of SchevoQt  
availability.

That said, it still needed a stable release version in order to  
support some Schevo apps that are already deployed and will need  
maintenance upgrades.  Therefore, you can install version 1.0a1 of  
SchevoQt by running this::

   easy_install -f http://schevo.org/files/releases SchevoQt

The reason the -f option is needed is because we chose not to  
announce SchevoQt on the cheeseshop.

"schevo nav" should be available once you install SchevoQt as noted  
above.

Hopefully by next month's release, we will have worked out the issues  
that bar us from gnav being a two-step install.  Ideally, those steps  
are:

   1. Install an official PyGTK distribution for Windows.
   2. easy_install SchevoGtk
   3. "schevo nav myapp.db"       <--  SchevoGtk navigator will  
become default "nav"

Stay tuned for that.  Sorry about the turmoil; hopefully this  
information will help!
