MyEclipse 5.1.1 GA Supports Eclipse 3.2.2 & Vi
RobK writes "The GA release of MyEclipse 5.1.1 is now available for immediate download and is compatible with Eclipse 3.2.2, Windows Vista. The release also includes an enhanced and professionally supported version of Eclipse WTP 1.5.3 with many MyEclipse improvements and bug fixes, as well as Fully I18N enabled. "
MyEclipse is an add on that enhances the base Eclipse package. www.myeclipseide.org for more info.
GA Release means General Availabiliy (a full release as opposed to a M releae, or milestone)
Vi looks like a typo, they meant Vista, I think.
Eclipse WTP is the Eclipse Web Tools Project.
I18n is shorthand for "internationalization".
All of which you would already have know if you actually used Eclipse like you said.
