The two releases immediately preceding current release fall under the
internal reasons. The older the release is, the less attention it gets. In
practice these preceding releases get quite a lot of fixes.
In this specific case MacOS Catalina was not available when OTP 21 was
current release and has therefore not gotten any fixes for Catalina.
