3.9.2

• track xdis API changes
• Bug fixes and lint

BlackHat Asia 2024 Ides of March

Lots of changes major changes. track xdis API has changes.

Separate Phases more clearly:

• disassembly
• tokenization
• parsing
• abstracting to AST (more is done in newer projects)
• printing

Although we do not decompile bytecode greater than 3.8, code supports running from up to 3.12.

Many bugs fixed.

A lot of Linting and coding style modernization.

Work done in preparation for Blackhat Asia 2024

• Fix Issues #310, #344, #377, #391, #409, #414
• Limited support for 3.8+ f-string "=" specifier
• Correct 2.5-7 relative import formatting

• Ensure no parenthesis subscript slices
• Correct 2.x formatting "slice2" nonterminal
• Correct 3.7 imports
• Improve "async for" parsing
• Handle BUILD_MAP opcode
• match Python AT better
• Correct 3.7 positional args
• PyPy 3.7 and PyPy 3.8 support
• Miscellaneous linting, isorting, blacking

Jed + Rocky average

• Better handling of invalid bytecode magic
• Support running from 3.9 and 3.10 although we do not support those bytecodes
• Redo version comparisons using tuples instead of floats. This is needed for Python 3.10
• Split out into 3 branches so that the master branch can assume Python 3.6+ conventions, especially type annotations
• Source Fragment fixes
• Lambda-bug fixes #360
• Bug fixes

3.7.4

• Fragment parsing was borked. This means deparsing in trepan2/trepan3k was broken
• 3.7+: narrow precedence for call tatement
• del_stmt -> delete to better match Python AST
• 3.8+ Add another forelsestmt (found only in a loop)
• 3.8+ Add precedence on walrus operator
• More files blackened
• bump min xdis version

3.7.3

Mostly small miscellaneous bug fixes

• __doc__ = DocDescr() from test_descr.py was getting confused as a docstring.
• detect 2.7 exchandler range better
• Add for .. else reduction checks on 2.6 and before
• Add reduce check for 2.7 augmented assign
• Add VERSION in a pydoc-friendly way

3.7.2

• Use newer xdis
• Docstrings (again) which were broken again on earlier Python
• Fix 2.6 and 2.7 decompilation bug in handling "list if" comprehensions

Fleetwood66

Released to pick up new xdis version which has fixes to read bytestings better on 3.x

• Handle 3.7+ "else" branch removal adAs seen in _cmp() of python3.8/distutils/version.py with optimization -O2
• 3.6+ "with" and "with .. as" grammar improvements
• ast-check for "for" loop was missing some grammar rules

Primidi 1st Prairial - Alfalfa - HF

The main impetus for this release is to pull in the recent changes from xdis.
We simplify imports using xdis 4.6.0.

There were some bugfixes to Python 3.4-3.8. See the ChangeLog for details

Love in the Time of Cholera

The main reason for this release is an incompatablity bump in xdis which handles
3.7 SipHash better.

• Go over "yield" as an expression precidence
• Some small alignment with code in decompyle3 for "or" and "and" was done
