sympa7 versioning

Sympa 7 versioning scheme [DRAFT]

Here versioning scheme for Sympa 7 is described.

Format of version string is one of following:

<major>.<minor>-<pre>

<major>.<minor>.<micro>

A version string consists of following parts:

<major> is major version number. It is always 7.
<minor> is minor version number. It should be increased whenever significant changes or additions are made.
One of <pre> and <micro> should exist.
- <pre> is pre-release version. alpha, beta or either of them suffixed by number, e.g. alpha11, beta3.
- <micro> is post-release patch level. It should begin with 0 by each minor version, and should be increased when insignificant changes or fixes are made.

These are bad examples and should not really be used.

7.0

No <pre> nor <micro>.
7.1.2-beta
7.1-beta.2
7.1-beta2.0

Both <pre> and <micro> appear.
7.1.22.1

Has the level lower than patch level (patch level with multiple columns does not matter).

This scheme will be applied to pre-release and stable versions of Sympa 7. Note that this scheme is not applied to prior versions of Sympa, 6.2.x and earlier.
However, until the community will have reached a consensus that the first stable version of Sympa 7 should be released, 7.0-alpha<n> (<n> is a number) will solely be used as version string.
