"""Fetches AWS lambda runtimes from https://docs.aws.amazon.com.

This script does not retrieve release dates, as they are only available in release announcements.
Instead, it uses the release dates from the endoflife.date product file. This has the advantage of
being warned about new releases, without having releaseDate information (wrongly) updated.

If one day release dates are available in the AWS documentation, it would be better to make use
them though. Note that this would also be unnecessary if it was possible to disable release/latest
release dates updates in the latest.py script."""
