Outdated Docker version support statement for version 1.9.1 (Nov 2015) #2366
Description
Current documentation
The README > Supported Docker versions document section currently states:
Supported Docker versions
This image is officially supported on Docker version 1.9.1.
Support for older versions (down to 1.6) is provided on a best-effort basis.
Please see the Docker installation documentation for details on how to upgrade your Docker daemon.
The statement was last updated 10 years ago and has long since ceased to be applicable.
Background
Docker Engine 1.9.1 was released in November 2015.
The current version of Docker Desktop according to release notes is 4.58 and it includes Docker Engine v29.1.5.
The GitHub Actions runner image ubuntu-24.04 currently uses Docker Client 28.0.4.
The latest Ubuntu 24.04 machine image release ubuntu-2404:2025.09.1 includes Docker Engine 28.4.0.
https://endoflife.date/docker-engine shows Docker Engine 25, 28 and 29 as supported.
Suggestion
Replace the current outdated support statement.
I don't however know exactly what it should be replaced with and if there are any current compatibility issues.
As far as Docker Desktop is concerned, they state in their release notes
Docker Desktop versions older than 6 months from the latest release are not available for download.
which sort of implies that the older versions are no longer supported.
