 - We publish containers for both `x86_64` and `aarch64` platforms, except for `tensorflow-notebook`, which only supports `x86_64` for now
 - Single-platform images have either `aarch64` or `x86_64` tag prefixes, for example `jupyter/base-notebook:aarch64-python-3.10.5`
 - Starting from `2022-09-21`, we create multi-platform images

+## Using old images
+
+This project only builds one set of images at a time.
+On `2022-10-09`, we rebuilt images with old `Ubuntu` and `python` versions for users who still need them:
