 - updated to upstream release 0.2.3
 
+Revision 0.2.3, released 25-02-2017
+-----------------------------------
+
+- Improved SEQUENCE/SET/CHOICE decoding performance by maintaining a single shared
+  NamedType object for all instances of SEQUENCE/SET object.
+- Improved INTEGER encoding/decoding by switching to Python's built-in
+  integer serialization functions.
+- Improved BitString performance by rebasing it onto Python int type and leveraging
+  fast Integer serialization functions.
+- BitString type usability improved in many ways: for example bitshifting and
+  numeric operation on BitString is now possible.
+- Minor ObjectIdentifier type performance optimization.
+- ASN.1 character types refactored to keep unicode contents internally
+  (rather than serialized octet stream) and duck-type it directly.
+- ASN.1 OctetString initialized from a Python object performs bytes()
+  on it when running on Python 3 (used to do str() which is probably
+  less logical).
+- Missing support for NoValue.__sizeof__ added.
+- Added checks to make sure SEQUENCE/SET components being assigned
+  match the prototypes.
+- Setter methods for constructed types consistently accept matchTags
+  and matchConstraints flags to control the strictness of inner
+  components compatibility verification. Previously, these checks
+  were tied to verifyConstraints flag, now they are all independent.
+- General documentation improvements here and there.
+- Fix to __reversed__() magic to make it returning an iterator.
+- Test suite simplified and unified.
+- The __all__ variable added to most of the Python modules.
+- The "test" directory renamed into "tests" not to collide with
+  the "test" module.
