Stairways Software today announced that has acquired from Michael Kamprath. Keyboard Maestro is a macro program for Mac OS X that allows users to design their own macros and activate them at any time, with support for selecting menus, opening files or applications, controlling iTunes, pasting text, etc. Originally developed as a part-time hobby, Kamprath said that he didn't currently have the resources to continue its development; beta testing for the next version, Keyboard Maestro 2.0, had been stretched out for over a year. Stairways said it will release a final version within the next three months and that it would target its informal one-paid upgrade per year policy. It is offering free upgrades to all new purchases ($20) after June 30th and a "nominal fee" upgrade path to other registered users.
