Adobe Premiere Version History

Premiere 4.2
The first version I remember.

Premiere 5.0, 5.1
This release saw some fundamental changes to the interface. Many users balked at first but most came to prefer the new, more professional way of doing things. Version 5 was not particularly stable but version 5.1 fixed most of the problems.

Premiere 6.0, 6.01
This release was much easier on Premiere users, with essentially the same interface and plenty of improvements. New features included DV capture and web video output.

Premiere 6.5
A relatively minor release. New features included: Real-time previewing, new titling tool, new audio effects, DVD authoring.

Premiere Pro (AKA Premiere Pro 1, Premiere 7, PPRO)
A significant release, this version was promoted by Adobe as a transition to the fully-professional arena. This version did not offer support for the Mac, an unusual move which was eventually rectified in Premiere Pro CS3.

Premiere Pro 1.5
A number of minor additions and bug fixes. Really just a more stable version of PPRO.

Premiere Pro 2
A moderately significant release, included a new interface and lots of new features such as: Record-to-DVD, Multi-camera editing, scrolling timeline, improved colour correction, GPU accelerated processing, native HD/HDV support, improved integration with other Adobe applications.

Premiere Pro CS3 (2007)
Relatively minor release, includes a few nice features such as time remapping. Now ships with Adobe Encore CS3. This version also sees a return of Mac support.
