@ -52,12 +52,18 @@ version MUST be reset to zero. When a minor version number is incremented, the
patch version MUST be reset to zero. For instance: 1.1.3 -> 2.0.0 and 2.1.7 ->
2.2.0.
1. A pre-release version number MAY be denoted by appending an arbitrary
string immediately following the patch version and a dash. The string MUST be
comprised of only alphanumerics plus dash [0-9A-Za-z-]. Pre-release versions
satisfy but have a lower precedence than the associated normal version.
Precedence SHOULD be determined by lexicographic ASCII sort order. For
instance: 1.0.0-alpha1 < 1.0.0-beta1 < 1.0.0-beta2 < 1.0.0-rc1 < 1.0.0.
1. A pre-release version number MAY be denoted by appending a dash and a
qualifying string immediately following the patch version. The qualifying
string is comprised of a mandatory identifier and an optional sequence number.
If the sequence number is used, it MUST be separated from the identifier by a
tilde. Identifiers MUST be comprised of only alphanumerics plus dash
[0-9A-Za-z-]. Sequence numbers MUST be comprised of only digits [0-9].
Pre-release versions satisfy but have a lower precedence than the associated
normal version. Precedence SHOULD be determined by lexicographic ASCII sort
order of the identifier followed by numeric sort order of the sequence number.
If the sequence number is absent, it MUST be considered to be zero. For
example: 1.0.0-alpha < 1.0.0-alpha~1 < 1.0.0-beta~2 < 1.0.0-beta~11 <
1.0.0-rc~1 < 1.0.0.
1. Once a versioned package has been released, the contents of that version
MUST NOT be modified. Any modifications must be released as a new version.
