As of v5.5, HotDog Professional is offered once again as a standalone editor (the Webmaster Suite also remains available for purchase). This release is priced more attractively at $99 but obviously doesn't include Linkbot, Paint Shop Pro, or mBed Interactor. There are evaluation downloads available from Sausage Software for both the standalone editor and the Webmaster Suite.
The v5.5 release of HotDog Pro also adds some important new features, including a redesigned interface that is much cleaner and more intuitive for new users (with a tabbed toolbar interface like Homesite), improved Web site management and FTP connectivity tools, an updated inline browser (Rover), most customization options, and significant performance improvements.
