What's new in PyASN1 0.1.8 RC 2
Feb 16, 2015
- ObjectIdentifier codec fixed to work properly with arc 0 and arc 2 values.
- Explicit limit on ObjectIdentifier arc value size removed.
- Unicode initializer support added to OctetString type and derivatives.
- New prettyPrintType() abstract method implemented to base pyasn1 types to facilitate encoding errors analisys.
- The __str__() method implemented to Tag, TagSet and TagMap classes to ease encoding errors troubleshooting. easing encoding errors
- Fix to SEQUENCE and SET types to give them their private componentTypes collection (which is a NamedTypes object) so that they won't collide in a MT execution environment.
- Missing T61String,ISO646String character types and ObjectDescriptor useful type added.
- Distribute is gone, switched to setuptools completely.
- Missing NamedValues.__repr__() added.
- The base.NoValue() class, that indicates uninitialized ASN.1 object, made public.
- The base.NoValue() class instances now support __repr__() what makes possible to perform repr() on uninitialized pyasn1 types objects.
- When comparing ASN.1 types, by-tag and/or by-constraints matching can now be performed with the isSuperTypeOf()/isSameTypeWith() optional flags.
- Constructed types now verify their consistency by invoking isSameTypeWith(matchTags=True, matchConstraints=False) and isSuperTypeOf(matchTags=False, matchConstraints=True) for each of their components rather than isSuperTypeOf() as it used to be. Constriants check could be enforced to isSameTypeWith() with the strictConstraints=True constructed classes attribute.
- Constructed types can now be initialized with new .setComponents() method which accepts both var-args and keyword-args. Default repr() modified to reflect this change.
- NamedTypes() and NamedValues() made comparable.
- Test coverage extended to cover pyasn1 types __repr__() function.
- The abs(Integer()) & abs(Real()) operation now returns respective pyasn1 type, not a Python type.
- More Python magic methods implementations added to Integer & Real classes (e.g. __pos__, __neg__, __round__, __floor__, __ceil__, __trunc__)
- The Integer.__invert__ Python magic method implemented.
- The OctetString.__int__() and .__float__() magic methods implemented.
- Handle the case of null writer at Debug printer.

- Float typed mantissa initializer to REAL type for base 2 added.
- Encoding bases 8 and 16 support for REAL type binary encoder added.
- Fix to REAL type binary decoder to handle different bases and scale factor.

New in PyASN1 0.1.8 RC 0 (Jun 3, 2013)

New in PyASN1 0.1.7 RC 2 (Feb 16, 2013)
- Test suite made discoverable by unittest/unittest2 discovery feature.
- Fix to decoder working on indefinite length substrate -- end-of-octets marker is now detected by both tag and value. Otherwise zero values may interfere with end-of-octets marker.

New in PyASN1 0.1.6 (Jan 30, 2013)
- The compact (valueless) way of encoding zero INTEGERs introduced in 0.1.5 seems to fail miserably as the world is filled with broken BER decoders. So we had to back off the *encoder* for a while.

- introduce and use in decoder the baseTagSet attribute of the built-in
- ASN.1 types.
