Hey ho -

after around 400 revisions the 0.4 branch is merged to trunk:

http://svn.sqlalchemy.org/sqlalchemy/trunk

Note that this version has some backwards incompatibilities with 0.3,
which have been described on this mailing list in a previous thread.
We also might be going with the name changes of "MetaData/Engine" to
"Catalog/Datasource" (feel free to chime in on that, anyone...?),
however the old names will remain available throughout 0.4 regardless
of what we do with that.

A document in progress describing 0.4 is at:

http://www.sqlalchemy.org/trac/wiki/WhatsNewIn04

Suffice to say that this new series is utterly huge.  I'm hoping it
provides a completely new level of experience in comparison to
anything previous.   We now have seven active committers, well over
800  unit tests and we're into the 3000s revision-wise...so the shape
of SQLAlchemy development is a completely different beast than it was
just a year ago.

My immediate focus is on documentation, which will start with just
getting all the new capabilities into the current document structure;
later, we might want to restructure/reformat the docs for clarity.  So
far just the chapter on "sessions" has a description of the new
transactional capabilities (and simplified interface) for Session; a
link to the docs-in-progress is on the "download" page of the site.

The remaining tickets on the 0.4 milestone, if not closed before
release, will move into the 0.4xx milestone.

Those working from 0.3 SVN should switch over to the maintenance
branch at:

http://svn.sqlalchemy.org/sqlalchemy/branches/rel_0_3

When we get an idea as to how easily people are upgrading to 0.4,
we'll figure out how aggressively we want to patch bug fixes from 0.4
back into 0.3 and continue releasing on that series.  Currently we
plan to keep 0.3 going as long as people need it.
