the first major upgrade was system 7.1.1, also known as "system 7 pro". this release was a bundle of 7.1 with applescript tools, quicktime and apple open collaboration environment (aoce). while system 7 had some trouble running in slightly older machines due to memory footprint, system 7 pro barely fit into any macintosh computers at the time. it was most commonly used for its minor bug fixes rather than its new functionality.
