Release Name: 5.0

Release Notes
FusionForge 5.0 is still an incremental step over 4.8, but many
changes have been made, some of which may require caution when
upgrading.

In particular, the rewriting of the version control subsystem created
the possibility for many new VCS tools to be integrated, and indeed
several new plugins were implemented (Arch, Bazaar, Darcs, Git and
Mercurial).  To avoid crowding the chroot, all repositories are now
hosted under a two-level subdirectory structure.  For instance, where
you had a CVS repositories stored under
/var/lib/gforge/chroot/cvsroot/<project>, you'll now have it under
.../chroot/scmrepos/cvs/<project>.  As a consequence, you need to move
the repositories by hand and/or add symlinks.  Previously existing
symlinks will also have to be updated, as well as previously existing
working copies obtained by users.

Also, the Mediawiki plugin was rewritten to allow for each project to
get their own independent wiki.  The wiki for project foo-bar is now
stored in the plugin_mediakiki_foo_bar in the same database as the
rest of the forge.  This means the data should be migrated from the
existing database to this new location.  Depending on your setup and
the amount of data involved, it might make sense to either cut and
paste by hand or dump the tables and reload them in the new schema.

On the internal side of things, access to the database has been
converted from the db_query() abstraction layer to the
db_query_params() one.  This means SQL queries are no longer built as
strings with unwieldy and fragile escaping code, while ensuring no
data coming from the user can be used for SQL injection attacks.  The
db_query() function, while deprecated, is still present for the
benefit of out-of-tree code that might use it.  It might be removed at
some point in the future, so maintainers of local plugins or
enhancements are encouraged to migrate their code to
db_query_params().  For really complex queries that need to be built
dynamically, there's also a db_query_qpa() abstraction, with a
db_construct_qpa() method to manipulate "QPA" (query+params array)
objects.

On a more visible note, the default theme has been reworked to
increase the accessibility of the web pages; this rewrite also brings
better maintainability, easier customisation by CSS and more
conformant XHTML.
