+.. _release9.3:
+
+9.3
+---
+* CommonString's ``.memoryview()`` raises ValueError now for
+ friendliness with linters
+
+.. _release9.2:
+
+9.2
+---
+* ``keep_memoryview`` context option appeared, respected by OctetString
+ and Any objects during DER decoding. If set, then their internal
+ values will keep memoryview reference instead of full bytes copy
+* Correspondingly OctetString and Any have ``.memoryview()`` method
+
+.. _release9.1:
+
+9.1
+---
+* ``.totzdatetime()`` appeared in UTCTime and GeneralizedTime,
+ explicitly setting UTC timezone information.
+ Optional ``dateutils.tz`` library is required for that
+
+.. _release9.0:
+
+9.0
+---
+* Drop Python 2.7 support. No ``six`` dependency anymore
+
+.. _release8.4:
+
+8.4
+---
+* Fix previous release's style breaking in ASN.1 browser
+
+.. _release8.3:
+
+8.3
+---
+* Append offsets to tree elements in ASN.1 browser for ease of navigation
+
+.. _release8.2:
+
+8.2
+---
+* Trivial documentation fixes
+
+.. _release8.1:
+
+8.1
+---
+* Workability under Microsoft Windows OS should be restored: it has
+ different ``mmap`` constants and implementation, preventing
+ ``pyderasn`` importing
+
+.. _release8.0:
+
+8.0
+---
+* **Incompatible** change: explicitly check that only naive datetime
+ objects are used for UTCTime and GeneralizedTime, raise an error
+ otherwise. Previously they silently ignored ``tzinfo``
+
+.. _release7.7:
+
+7.7
+---
+* Strictly check that tag's long encoded form does not contain leading zero
+ (X.690 8.1.2.4.2 (c))
+* Strictly check that tag's long form is used in expected way for small values
+ (X.690 8.1.2.2)
+
+.. _release7.6:
+
+7.6
+---
+* Proper strict alphabet validation of VisibleString
+* VisibleString and IA5String also have ``allowable_chars`` property
+* Fixed TeletexString, T61String use ``iso-8859-1`` encoding (instead of
+ ``ascii``), because they are 8-bit encodings
+
+.. _release7.5:
+
+7.5
+---
+* Also print full TLVlen in ASN.1 browser
+
+.. _release7.4:
+
+7.4
+---
+
+* Fix DEFINED BY pprinting when invoking as __main__ module
+* Integer has ``tohex()`` for getting hexadecimal representation of its value
+* ``hexdump()`` (``hexdump -C`` like output) and ``ascii_visualize()``
+ (visualize ASCII printable characters, like in ``hexdump -C``) pretty
+ printing functions appeared
+* Experimental ASN.1 interactive terminal browser (``--browse`` and
+ ``pyderasn.browse``).
+ You will need `urwid package <http://urwid.org/>`__ to use it
+
+.. _release7.3:
+
+7.3
+---
+
+* SEQUENCE/SET fully performs default value existence validation in
+ evgen mode, by the cost of DEFAULTed value full decoding. That should
+ not be the problem, as DEFAULTs are relatively small in practice. Now
+ evgen mode has the same DER validation strictness as an ordinary one
+
+.. _release7.2:
+
+7.2
+---
+
+* Restored workability of some command line options
+* 2-pass DER encoding mode with very little memory footprint
+
+.. _release7.1:
+
+7.1
+---
+
+* README updating
+
.. _release7.0:
7.0
by tag, but by encoded representation
* ``Any`` does not allow empty data value now. Now it checks if it has
valid ASN.1 tag
+* ``SetOf`` is not treated as ready, if no value was set and minimum
+ bounds are greater than zero
* ``Any`` allows an ordinary ``Obj`` storing, without its forceful
- encoded representation storage
+ encoded representation storage. That is required for CER encoding
+ mode, where we do not know in advance what encoding will be used
+* ``ObjectIdentifier`` stores values as C unsigned long integer,
+ forbidding storage of huge integers, that must not be a problem in
+ practice
* 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
6.1
---
* UTCTime and GeneralizedTime allowed values to have plus sign in them,
- passing int() check successfully. Prohibit that incorrect behaviour
+ passing ``int()`` check successfully. Prohibit that incorrect behaviour
* UTCTime and GeneralizedTime BER decoding support
* Faster UTCTime and GeneralizedTime decoding, and slightly better
overall performance
