ChangeLog
=========
+2.5.0 (master)
+--------------
+
+*Bugfix:*
+
+ `#18 <https://github.com/rbarrois/python-semanticversion/issues/18>`_: According to SemVer 2.0.0, build numbers aren't ordered.
+
+ * Remove specs of the ``Spec('<1.1.3+')`` form
+ * Comparing ``Version('0.1.0')`` to ``Version('0.1.0+bcd')`` has new
+ rules::
+
+ >>> Version('0.1.0+1') == Version('0.1.0+bcd')
+ False
+ >>> Version('0.1.0+1') != Version('0.1.0+bcd')
+ True
+ >>> Version('0.1.0+1') < Version('0.1.0+bcd')
+ False
+ >>> Version('0.1.0+1') > Version('0.1.0+bcd')
+ False
+ >>> Version('0.1.0+1') <= Version('0.1.0+bcd')
+ False
+ >>> Version('0.1.0+1') >= Version('0.1.0+bcd')
+ False
+ >>> compare(Version('0.1.0+1'), Version('0.1.0+bcd'))
+ NotImplemented
+
+ * :func:`semantic_version.compare` returns ``NotImplemented`` when its
+ parameters differ only by build metadata
+ * ``Spec('<=1.3.0')`` now matches ``Version('1.3.0+abde24fe883')``
+
