I am confused by the version number of docker

Some documentation refers to version numbers like 17.06 E.g. (from here)

However, starting with Docker 17.06, you can also use --mount with standalone containers

But some other documentation refers to version number like 1.13 E.g. (from here)

Note: version 1.13 or higher is required

Was the version numbering convention changed at some point in time?

    *"Was the version numbering convention changed at some point in time?"* Yes: https://blog.docker.com/2017/03/docker-enterprise-edition/. If you click on the version drop-down in the docs, you can see that it goes 1.12, 1.13, 17.03, 17.06. – jonrsharpe Oct 07 '17 at 11:01

17.03.0-ce (2017-03-01)

IMPORTANT: Starting with this release, Docker is on a monthly release cycle and uses a new YY.MM versioning scheme to reflect this. Two channels are available: monthly and quarterly. Any given monthly release will only receive security and bugfixes until the next monthly release is available. Quarterly releases receive security and bugfixes for 4 months after initial release. This release includes bugfixes for 1.13.1 but there are no major feature additions and the API version stays the same. Upgrading from Docker 1.13.1 to 17.03.0 is expected to be simple and low-risk.

It was changed from 17.03. Which is march release for this year

    I just got prompted for a Docker update on my Macbook, I have 18.06.0 installed, and it's prompting me to update to 2.0.0.0-beta1. Have they gone back to the old versioning scheme? – Bill Karwin Oct 04 '18 at 15:12

    Aha - Docker Engine is 18.09.0, but Docker Desktop is 2.0.0.0. The latter includes the former. – Bill Karwin Oct 04 '18 at 15:14

    Thanks very much! Updating some old hosts and I couldn't find those notes about the numbering changes anywhere but here! – Mike Diehn Jul 03 '19 at 15:02
  • The answer does not share from which weblink/document/artifact reference its excerpt is taken. Can someone please share this? – Johnny Utahh Apr 05 '20 at 01:45

  • Thanks @TarunLalwani. I think it best that Docker clear up confusion around what's going on with their version-and-release-management process: https://www.reddit.com/r/docker/comments/fv65v9/docker_version_scheme_what_happened_to_release/fmi5ipl/. – Johnny Utahh Apr 05 '20 at 16:31
