To anyone that isn’t aware, Lester Chan (GaMerZ) is a WordPress plugin author that has released some very useful plugins that I use myself on this site, including the WP-PageNavi (for page navigation) and Download Manager (for tracking downloads on the free WordPress themes page).
He has just announced a few days ago a large portion of his plugins are now updated and compatible with WordPress 2.5 and above. The full list of updated plugins can be viewed on that link. For the remaining plugins, there are beta versions available on the Downloads page. These are supposed to work with 2.5, but have not been thoroughly tested and therefore, still in beta.
