 The lowest previously used Alpine Linux release is dropped for future image builds,
 so that only the two latest releases are maintained.

+If a [Debian LTS](https://wiki.debian.org/LTS) transition causes any architectures used in Docker builds to be dropped,
+they are also dropped from future builds after waiting for the next Node.js release
+following the Debian release transition into LTS support.
+The wait is advised to prevent an architecture being prematurely removed due to the automatic rebuild process
+in [docker-library/official-images](https://github.com/docker-library/official-images).

+After the end of Debian LTS support, the corresponding Debian release is dropped for future image builds.
