Not sure if you all remember TuneUp Media (the program that would clean up your MP3 collection and add tags and artwork, etc), but this reminds me of them. They came out with a "big" 3.0 update and everything feel apart. For them, I think EVERY customer had problems with the release. People were losing years of work and data. It was bad bad bad. It got so bad they ended up selling the company to some of the employees. I'm not sure they ever pulled through it. Very interested case study and read though (but painful experience for those of us who went through it): https://www.networkworld.com/article/2224351/when-bad-things-happen-to-good-apps--part-1.html
