Salt uses a date based system for version numbers. Version numbers are in the
YYYY.MM.R. The year (
YYYY) and month (
MM) reflect when the
release was created. The bugfix release number (
R) increments within that
Prior to the
2014.1.0 release, the typical semantic versioning was
still being used. Because of the rolling nature of the project, this did not
make sense. The
0.17 release was the last of that style.
To distinguish future releases from the current release, code names are used.
The periodic table is used to derive the next codename. The first release in
the date based system was code named
Hydrogen, each subsequent release will
go to the next atomic number <https://en.wikipedia.org/wiki/List_of_elements>.
An example might help clarify how this all works.
It is the year
2020 and the current code name is
Iodine. A release is ready
to be cut and the month is
June. This would make the new release number
2020.6.0. After three bug fix releases, the release number would be
After the release is cut, new features would be worked on under the
code name and the process repeats itself.
The salt version, for programmers, is based on git describe and presented to end-users with salt --version.
Example arguments for git checkout:
Argument Comment develop Develop branch Actively developed new features 2016.11 Release branch Actively developed bug-fixes for 2016.11.* releases v2016.11 Tag signaling the commit that the 2016.11.* releases are based on. v2016.11.1 Tag signaling the commit that the 2016.11.1 release is based on.

Influence of the git checkout argument on git describe:
Checkout Describe Comment v2016.11 v2016.11 (tag is fixed point in time) 2016.11 v2016.11.1-220-g9a1550d Commit of most recent tag in 2016.11 v2016.11.1 2016.11.1 (tag is fixed point in time) develop v2016.11.1-1741-g10d5dec Commit of most recent tag in develop
