+.. _release7.0:
+
+7.0
+---
+* Fixed invalid behaviour where SET OF allowed multiple objects with the
+ same tag to be successfully decoded
+* Fixed possibly invalid SET DER encoding where objects were not sorted
+ by tag, but by encoded representation
+* ``Any`` does not allow empty data value now. Now it checks if it has
+ valid ASN.1 tag
+* ``Any`` allows an ordinary ``Obj`` storing, without its forceful
+ encoded representation storage
+* Initial support for so called ``evgen_mode``: event generation mode,
+ where no in-memory objects storing happens, giving ability to process
+ ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
+ ``--evgen`` mode switcher
+* Useful ``agg_octet_string`` that is able to streamingly decode string
+ from events of ``evgen_mode``, allowing strings retrieving without
+ copying them to memory first
+* Initial experimental CER encoding mode, allowing streaming encoding of
+ the data directly to some writeable object
+* Ability to use mmap-ed memoryviews to skip files loading to memory
+
+.. _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
