+- update to version 0.4.2:
+  * Fixed explicit tag splitting in chunked encoding mode at
+    OctetString and BitString encoders
+
+- changes from version 0.4.1:
+  * ANY DEFINED BY clause support implemented
+  * Encoders refactored to take either a value (as ASN.1 object) or a
+    Python value plus ASN.1 schema
+  * BitString decoder optimised for better performance when running on
+    constructed encoding
+  * Constructed types' .getComponentBy*() methods accept the `default`
+    parameter to return instead if schema object is to be returned
+  * Constructed types' .getComponentBy*() methods accept the
+    `instantiate` parameter to disable automatic inner component
+    instantiation
+  * The ASN.1 types' `__repr__` implementation reworked for better
+    readability at the cost of not being `eval`-compliant
+  * Most ASN.1 types' `__str__` magic methods (except for OctetString
+    and character types) reworked to call `.prettyPrint()` rather than
+    `.prettyPrint` calling `__str__` as it was before. The intention
+    is to eventually deprecate `.prettyPrint()` in favor of `str()`.
+    The other related change is that `str()` of enumerations and
+    boolean types will return string label instead of number.
+  * Fixed Choice.clear() to fully reset internal state of the object
+  * Sphinx documentation rearranged, simplified and reworded
+  * The `isValue` singleton is now the only way to indicate ASN.1
+    schema as opposed to ASN.1 schema instance. The legacy `None`
+    initializer support has been removed.
+  * Changed `Null` object initialization behaviour: previous default
+    value (`''`) is not set anymore. Thus `Null()` call produces a
+    ASN.1 schema object, while `Null('')` - value object.
+  * Migrated all docs and references from SourceForge
+  * Imports PEP8'ed
+  * Fixed ASN.1 encoder not to omit empty substrate produced for inner
+    component if the inner component belongs to the simple class (as
+    opposed to constructed class)
+  * Fixed CER/DER encoders to respect tagged CHOICE when ordering SET
+    components
+  * Fixed ASN.1 types not to interfere with the Pickle protocol
+  * Fixed Sequence/SequenceOf types decoding heuristics in schema-less
+    decoding mode
