Edinburgh-based developer Runtime Revolution has released its software-development environment Revolution 2.0 following extensive beta testing.

Revolution 2.0 can be used to build applications for Mac OS X, Classic Mac OS, Windows, Linux and Unix. It offers a user-friendly interface and a powerful yet easy-to-use object-based programming language, says the company.

Company CEO Kevin Miller said: "Using Revolution cuts the time to develop an application by up to a factor of ten. We've re-engineered Revolution from the ground up for even higher productivity levels."

Revolution 2.0 introduces 118 new features and 500 enhancements. These include new XML libraries; SOAP (Simple Object Access Protocol) support; a more OS X-like user interface; Unicode text entry, manipulation, conversion and an automatic report generator.

Multiple platform versions of Revolution 2.0 are now available, and a 30-day fully featured evaluation edition can be downloaded.

The products costs between $99-$995. The Professional Edition ($995) offers full database access, technical support by email, and all updates for a year. Also available is the Small Business Edition ($299), which does not have the database access and technical support by email facility, but does offer a year's update. A $99 Student-Teacher edition is also available.
