Not only with intervals but also with quite old software. Sometimes software versions are so old that they are no longer compatible with the upstream version. Although, to be honest, I haven't used Debian for so long that I can't even name the applications that lagged behind like that.
In general, Debian is indeed incredibly stable, but if you need to install it on the latest laptop (for example, Intel Core Ultra X9), it will be a real hell.
UPD: except perhaps for using sid. But then you lose the only advantage - stability.
