+.. _release7.0:
+
+7.0
+---
+* Fixed invalid behaviour where SET OF allowed multiple objects with the
+ same tag to be successfully decoded
+
+.. _release6.3:
+
+6.3
+---
+* Fixed workability under Python 3.5. Previously only 2.7 and 3.6
+ versions were tested
+
+.. _release6.2:
+
+6.2
+---
+* Python ``int()``'s accepts even more various non-decimal characters
+ than expected. Make validation fully strict in UTCTime and
+ GeneralizedTime, without relying on ``int()``
+
+.. _release6.1:
+
+6.1
+---
+* UTCTime and GeneralizedTime allowed values to have plus sign in them,
+ passing int() check successfully. Prohibit that incorrect behaviour
+* UTCTime and GeneralizedTime BER decoding support
+* Faster UTCTime and GeneralizedTime decoding, and slightly better
+ overall performance
+* Workability under Cython
+* Explicitly Check that all ObjectIdentifier arcs are non-negative
+
+.. _release6.0:
+
+6.0
+---
+* ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
+ objects now
+* Copies made previously with ``.copy()`` lacked ``.defined`` field,
+ now they are not
+* All objects are friendly to ``pickle`` libraries
+* PrintableString has ``allow_asterisk`` and ``allow_ampersand``
+ properties
+* ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
+ appeared, working with hexadecimal encoded data
