Where publish add-on: OLD or NEW website?

Where must be published a new add-on?

Old site: https://projects.blender.org/tracker/?func=browse&group_id=153&atid=467

or

New site: http://developer.blender.org/

Hi, I’m not 100% sure, but I would wait until around next week when they have migrated everything over to the new site (should start wednesday followed by a couple of days downtime).

yep, wait until migration is done. Then use the “Submit Addon” button, it’s already on the page.
