[development] release system is live, drupal.org is back

[Derek Wright]

i forgot this in the initial draft of http://drupal.org/node/ 
94000#developers

*Note*: During this conversion, release nodes were automatically  
generated for all of your existing stable branches (e.g. DRUPAL-4-7,  
DRUPAL-4-6, etc) that were being packaged (e.g. the old 4.7.0 version  
of your module or theme). So, you will *not* need to add release  
nodes for these branches, and when trying to add new release nodes,  
these branches will not show up in the list of available CVS  
identifiers, since they're already in use by an existing release.

...

already got an issue by someone confused by this (http://drupal.org/ 
node/96969) so i figured i should broadcast this info.
