Mac OS (yes, the 68k OS) were considered stable every other release as well; all the odd major numbered OS always requires endless number of patches (keep in mind that back then, there was no broadband to ease patch distribution.) With the exception of OS8 (which was released to get out of contracts with Mac clone makers,) even numbered versioned OSes were considered more "mature" than the odd numbered versioned OSes.
