ASM is the reincarnation of the application switcher menu. It's highly customizable and offers some nice extra features, such as "Classic Window Mode" (orders all windows of an application to front when it becomes active) or "Single Application Mode" (automatically hides applications other than the front-most one).
What's new in version 2.3
adds compatibility with Mac OS X 10.6 a.k.a. Snow Leopard, though the dock menu feature is currently not supported and possibly never will.
ASM 2.3 is a free upgrade for existing customers who purchased a license after 2009-02-28. Otherwise you have to purchase a new license. This is a change of policy, in the course of nearly seven years updates were free for existing customers. At the same time I set a substantially lower price for ASM: 6.99 EUR (plus taxes) for a single user license.
