There’s a difference between stability and reliability. Stable means that functionality is the same over a period of time, no major changes to how it works. Reliable means that it doesn’t crash all the time. If something crashes the same way for the same reason, it’s stable but not reliable. If something changes a lot but doesn’t crash, it’s reliable but not stable.
In practice what it comes down to is a choice if you want outdated but known bugs or new surprise bugs.
