AAA+ has released Joy 2.2, a Mac OS X-native application for developers.
Joy can be used with Apple's InterfaceBuilder to develop and de-bug standalone Mac OS X applications.
Features new to Joy 2.2 include autoloading of Objective-C (a software development code) scripts. Joy also includes improved support for scripted WebObjects applications.
Licences to develop applications that only use a small number of Joy's features cost $69. It costs $399 for unlimited use.
