Gallery 3 is going to a big change from current gallery 2 and initial alpha release did not have any migration path from gallery2. It was pushed to Beta release after 2 alpha releases. but to my surprise I found it was implemented in alpha 4 and here is the test result of a new neat code. I am really liking the new compact code making gallery 3 faster and lean compared to its predecessor. Similar, to WordPress new theme development is easy no more smarty - thank God I never really mastered those PERL look alike. Now it is simple PHP and CSS. Another core feature is Akismet which does a fantastic job of filtering spam comments. I was able to import 3000+ images in 200+ albums without any problem. There are few things which needs to be ironed before I can put the same in production.
