-        The server version has three parts:
+        Follows the Semantic Versioning Specification:
 
-            <major>     A non negative integer.
-            <minor>     An integer between 0 and 999 inclusive.
-            <suffix>    An optional string. For example, "rc1"
-
-        The version string is formatted thusly:
-
-            <major> '.' <minor> ['-' <suffix>]
-
-        The minor version number is always padded with leading zeroes
-        to bring the number of characters up to exactly three. For example,
-        the server version string "12.045-rc1" has major version 12, minor
-        version 45, and suffix "rc1". A suffix may only consist of lowercase
-        letters and digits, and must start with a letter. The suffix may
-        be up to 4 characters. The major version may not be prefixed with
-        extra leading zeroes.
-
-        The suffix for a new official release is usually omitted. If hotfixes
-        are added to official releases they get a single leter suffix.
-
-        Release candidates are marked with suffixes starting with "rc" and
-        followed by a number starting from 1 to indicate the first
-        release candidate, with subsequent release candidates incrementing
-        the number. A final release candidate which becomes an official
-        release loses the suffix. The next release candidate will have a
-        new major or minor version number, and start back at "rc1".
