Release 0.3.5

This is mostly a bug fix release. Most important fixes include:

• Explicit tag encoding optimized to avoid unnecessary copying
• End-of-octets sentinel encoding optimized
• Refactored ASN.1 codecs properties to silently enforce proper length and chunk size encoding modes
• Fixed DER encoder to always produce primitive encoding
• Fixed crash at SequenceOf native decoder
• Fixed a couple of crashes when debug mode is enabled

More changes noted in the CHANGELOG.

Release 0.3.4

This is mostly a bug fix release. Most important fixes include:

• Added missing component-less SEQUENCE/SET objects dict duck-typing support
• Fixed crash at SEQUENCE and SEQUENCE OF CER encoder when running in schemaless mode
• Fixed Character types instantiation from OctetString type -- double unicode decoding may have scrambled the data

More changes noted in the CHANGELOG.

Release 0.3.3

This is a bugfix release addressing a handful of regressions introduced in 0.3.2.

Most importantly:

• Fixed exponential index size growth bug when building ambiguous NamedTypes tree
• Fixed constructed types decoding failure at BER codec if running in unguided mode
• Fixed SetOf ordering at CER/DER encoder

More changes noted in the CHANGELOG.

Release 0.3.2

This is a bugfix release addressing a handful of regressions introduced in 0.3.1.

Most importantly:

• Fixed SequenceOf/SetOf types initialization syntax to remain backward compatible with pyasn1 0.2.*
• Rectified thread safety issues by moving lazy, run-time computation into object initializer.
• Fixed GeneralizedTime/UTCTime CER/DER codecs to actually get invoked
• Fixed DER/CER encoders handling optional SEQUENCE/SET fields containing nested SEQUENCE/SET with optional fields.

More changes noted in the CHANGELOG.

Release 0.3.1

The main theme for this release is API and performance improvements.

Be aware that by way of usability improvements, a some backward compatibilities were introduced. For the details please refer to the CHANGELOG.

The highlights:

• ASN.1 types __init__(), .clone() and .subtype() signatures refactored to expect keyword arguments
• Many "getters" of ASN.1 types refactored into Python properties
• SetOf/SequenceOf ASN.1 types better mimic Python list
• The NamedValues implementation refactored to mimic Python dict
• The GeneralizedTime and UTCTime types now support to/from Python datetime object conversion
• Many minor performance improvements and bug fixes

More changes noted in the CHANGELOG.

Release 0.2.3

This is a performance improvement release:

• BitString type implementation rebased onto Python int to behave like an integer and improve serialization performance (100x times!).
• Integer codecs reimplemented to base on Python's built-in integer serialization codecs to improve serialization performance (~40%).
• Decoding performance of Set and Choice types improved by caching once computed tags maps.
• ASN.1 character types refactored to duck-type unicode strings thus making them more convenient in text processing context.
• Documentation updated at many places.

More changes noted in the CHANGELOG.

Release 0.2.2

This release fixes a regression in Enumerated ASN.1 type subtyping procedure.

Besides that, canonical decoders were hardened to reject non-canonical serialization on input.

More details can be learned from the change log

Release 0.2.1

This is a bug fix and usability improvement release:

• Conversion between Python built-in types and pyasn1 objects implemented
• Python types emulation improved to make pyasn1 types look more like their Python counterparts
• BitString type usability improved in many ways
• Sphinx documentation added

More changes noted in the CHANGELOG.

The upcoming release is to be focused on codecs performance improvement.
