Due to Pharo/Smalltalk being not just a language, but a language/libraries/IDE, I think it's important to distinguish between API instability (which IHMO is better called evolution) vs. bugginess. API evolution is a core part of Pharo's mission. I've personally upgraded projects from Pharo 1.x all the way to Pharo 7 and have been very willing to trade a small amount of effort porting for big increases in productivity.
