How does Debian maintain stability in its stable releases?

Ah, Debian's stability is definitely one of my favorites too. When I looked into it, I wasn't surprised to see that Stable outperforms both Testing and Unstable branches in terms of reliability. The key here is that packages are tested *thoroughly* before they even arrive. Sometimes years pass between a package hitting Testing and making it to Stable—like I experienced during the ["stretch" era](https://www.debian.org/releases/stretch/), where updates were slow but my system never once broke. To really see how Stable stands apart, let’s compare it this way: in Testing, packages are fresh but not necessarily stabilized—once, I saw a system crash in Testing, even needing to restart X because of an app. In the unstable branches, debugging is a constant process, but Stable only updates with thoroughly tested and approved changes. That’s why Debian can run for years in production environments—I use Stable on my own servers and never had serious issues, whereas I’ve struggled multiple times running Testing on the same hardware.
