WordPress.org has announced that they have targeted early December, 2012, for the release of WordPress Version 3.5.
We will do our best to be sure Weaver II works perfectly with WordPress 3.5, and plan to continue support and development of Weaver II for the foreseeable future. (No current plans for Weaver III, for example.)
However, because of certain technical issues and requirements of the WordPress.org theme repository, we will be dropping support for the old version – Weaver 2.2.x – as of the release of WordPress 3.5.
This does not mean that Weaver 2.2.x will stop working with WordPress 3.5 (in fact, it is quite likely that it will continue to work for some time as WordPress usually tries to maintain backward compatibility). But we will not update Weaver 2.2.x. It is also likely that Weaver 2.2.x will be removed completely from the WordPress.org theme repository.
Given this decision, if you are still using Weaver 2.2.x, it may be time to consider upgrading to Weaver II. See this FAQ: http://weavertheme.com/upgrading-from-original-weaver-to-weaver-ii/
