+
+
+release 2.4 (Dan Pascu)
+  - Replaced the way code structures are identified by the parser.
+    Previously, the scanner introduced some COME_FROM entries in the
+    dissasembly output to mark all the destinations of jump instructions.
+    Using these COME_FROM labels the parser was then able to identify the
+    code structures (if tests, while loops, etc). Up to python-2.3 this was
+    possible because the code structures were clearly defined and jump
+    targets were always to the same points in a given strcuture making it
+    easy to identify the structure. Python 2.3 however introduced optimized
+    jumps to increase code performance. In the previous version of decompyle
+    (2.3) we used a technique to identify the code structures and then used
+    these structures to determine where the jump targets would have been if
+    not optimized. Using this information we then added COME_FROM labels at
+    the points where they would have been if not optimized, thus emulating
+    the way decompyle worked with versions before python 2.3. However with
+    the introduction of even more optimizations in python 2.4 this technique
+    no longer works. Not only the jump targets are no longer an effective
+    mean for the parser to identify the code structures, but also trying to
+    emulate the old way things were solved when it clearly no longer works
+    is not the right solution. To solve this issue, the code to identify the
+    structures that we had developed in version 2.3, was used to add real
+    start/end points for strcuture identification, instead of the COME_FROM
+    labels. Now these new start/end labels are used by the parser to more
+    precisely identify the structures and the COME_FROM labels were removed
+    completely. The scanner is responsible to identify these code structures
+    and use any knowledge of optimizations that python applies to determine
+    the start/end points of any structure and then mark them with certain
+    keywords that are understood by the parser.
+  - Correctly identify certain `while 1' structures that were not
+    recognized in the previous version.
+  - Added support for new byte code constructs used by python 2.4
+
+release 2.3.2
+  - tidied up copyright and changelog information for releases 2.3 and later
+
+release 2.3.1 (Dan Pascu)
+  - implemented a structure detection technique that fixes problems with
+    optimised jumps in Python >= 2.3. In the previous release (decompyle 2.3),
+    these problems meant that some files were incorrectly decompiled and
+    others could not be decompiled at all. With this new structure detection
+    technique, thorough testing over the standard python libraries suggests
+    that decompyle 2.3.1 can handle everything that decompyle 2.2beta1 could,
+    plus new Python 2.3 bytecodes and constructs.
+
+release 2.3 (Dan Pascu)
+  - support for Python 2.3 added
+  - use the marshal and disassembly code from their respective python
+    versions, so that decompyle can manipulate bytecode independently
+    of the interpreter that runs decompyle itself (for example it can
+    decompile python2.3 bytecode even when running under python2.2)
+
+——————————————————
+
+release 2.2beta1 (hartmut Goebel)
+  - support for Python 1.5 up to Python 2.2
+  - no longer requires to be run with the Python interpreter version
+    which generated the byte-code.
+  - requires Python 2.2
+  - pretty-prints docstrings, hashes, lists and tuples
+  - decompyle is now a script and a package
+  - added emacs mode-hint and tab-width for each file output
+  - enhanced test suite: more test patterns, .pyc/.pyo included
+  - avoids unnecessary 'global' statements
+  - still untested: EXTENDED_ARG
+
+  internal changes:
+  - major code overhoul: splitted into several modules, clean-ups
+  - use a list of valid magics instead of the single one from imp.py
+  - uses copies of 'dis.py' for every supported version. This ensures
+    correct disassemling of the byte-code.
+  - use a single Walker and a single Parser, thus saving time and memory
+  - use augmented assign and 'print >>' internally
+  - optimized 'Walker.engine', the main part of code generation
+release 0.6.0: (hartmut Goebel)
+  - extended print (Python 2.0)
+  - extended import (Python 2.0) (may not cover all cases)
+  - augmented assign (Python 2.0) (may not cover all cases)
+  - list comprehensions (Python 2.0)
+  - equivalent for 'apply' (Python 1.6)
+  - if .. elif .. else are now nested as expected
+  - assert test, data
+  - unpack list corrected (was the same as unpack tuple)
+  - fixed unpack tuple (trailing semicolon was missing)
+  - major speed up :-)
+  - reduced memory usage (pre-alpha-0.5 has increased it a lot)
+  - still missing: EXTENDED_ARG
+
+pre-alpha-0.5: (hartmut Goebel)
+  - *args, **kwargs
+  - global

+  - remove last 'return None' in procedures
+  - remove last 'return locals()' in class definitions
+  - docstrings
+
+pre-alpha-0.4: (hartmut Goebel)
+  - assert
+  - try/except/finally
+  - parentheses in expressions
+  - nested expressions
+  - extracted dissassemble() from module dis and

+# How to report a Bug
+
+## The difficulty of the problem
+
+There is no Python decompiler yet, that I know about that will
+decompyle everything. This one probably does the
+best job of *any* Python decompiler. But it is a constant work in progress: Python keeps changing, and so does its code generation.
+
+I have found bugs in *every* Python decompiler I have tried. Even
+those where authors/maintainers claim that they have used it on 
+the entire Python standard library. And I don't mean that
+the program doesn't come out with the same Python source instructions,
+but that the program is *semantically* not equivalent.
+
+So it is likely you'll find a mistranslation in decompiling.
+
+## What to send (minimum requirements)
+
+The basic requirement is pretty simple:
+
+* Python bytecode
+* Source text
+
+## What to send (additional helpful information)
+
+Some kind folks also give the invocation they used and the output
+which usually includes an error message produced. This is helpful. I
+can figure out what OS you are running this on and what version of
+*uncomplye6* was used. Therefore, if you don't provide the input
+command and the output from that, please give:
+
+* _uncompile6_ version used
+* OS that you used this on
+* Python interpreter version used
+
+
+### But I don't *have* the source code!
+
+Sure, I get it. No problem. There is Python assembly code on parse
+errors, so simply by hand decompile that. To get a full disassembly, use pydisasm from the [xdis](https://pypi.python.org/pypi/xdis) package. Opcodes are described in the documentation for the [dis](https://docs.python.org/3.6/library/dis.html) module.
+
+### But I don't *have* the source code and am incapable of figuring how how to do a hand disassembly!
+
+Well, you could learn. No one is born into this world knowing how to disassemble Python bytecode. And as Richard Feynman once said, "What one fool can learn, so can another."
+
+## Narrowing the problem
+
+I don't need the entire source code base for which one file or module
+can't be decompiled. I just need that one file or module only. If
+there are several files, file a bug report for each file.
+
+Python modules can get quite large, and usually decompilation problems
+occur in a single function or maybe the main-line code but not any of
+the functions or classes. So please chop down the source code by
+removing those parts that do to decompile properly.
+
+By doing this, you'll probably have a better sense of what exactly is
+the problem. Perhaps you can find the boundary of what decompiles, and
+what doesn't. That is useful. Or maybe the same file will decompile
+properly on a neighboring version of Python. That is helpful too.
+
+In sum, the more you can isolate or narrow the problem, the more
+likley the problem will be fixed and fixed sooner.

 Introduction

 *uncompyle6* translates Python bytecode back into equivalent Python

-so and has been tested on Python running versions 2.6, 2.7, 3.3,

+code is used. This code pulls these together and moves forward. This
+project has the most complete support for Python 3.3 and above. It
+also addresses a number of open issues in the previous forks.

-Other parts of the library can be used inside Python for various

-the bytecode using a version of Python different from the one used to
-compile the bytecode.

+If you want strong verification of the correctness of the
+decompilation process, add the `--verify` option. But there are
+situations where this will indicate a failure, although the generated
+program is semantically equivalent. Using option `--weak-verify` will
+tell you if there is something definitely wrong. Generally, large
+swaths of code are decompiled correctly, if not the entire program.
+
+You can also cross compare the results with pycdc_ . Since they work
+differently, bugs here often aren't in that, and vice versa.
 
 
 Known Bugs/Restrictions
 -----------------------
 
-Python 2 deparsing is probably as solid as the various versions of
-uncompyle2.  Python 3 deparsing is okay but not as solid.
+The biggest known and possibly fixable (but hard) problem has to do
+with handling control flow. All of the Python decompilers I have looked
+at have the same problem. In some cases we can detect an erroneous
+decompilation and report that.
+
+Over 98% of the decompilation of Python standard library packages in
+Python 2.7.12 verifies correctly. Over 99% of Python 2.7 and 3.3-3.5
+"weakly" verify. Python 2.6 drops down to 96% weakly verifying.
+Other versions drop off in quality too.
+
+*Verification* is the process of decompiling bytecode, compiling with
+a Python for that bytecode version, and then comparing the bytecode
+produced by the decompiled/compiled program. Some allowance is made
+for inessential differences. But other semantically equivalent
+differences are not caught. For example ``1 and 0`` is decompiled to
+the equivalent ``0``; remnants of the first true evaluation (1) is
+lost when Python compiles this. When Python next compiles ``0`` the
+resulting code is simpler.
+
+*Weak Verification*
+on the other hand doesn't check bytecode for equivalence but does
+check to see if the resulting decompiled source is a valid Python
+program by running the Python interpreter. Because the Python language
+has changed so much, for best results you should use the same Python
+Version in checking as used in the bytecode.
+
+Later distributions average about 200 files. There is some work to do
+on the lower end Python versions which is more difficult for us to
+handle since we don't have a Python interpreter for versions 1.5, 1.6,
+and 2.0.
+
+In the Python 3 series, Python support is is strongest around 3.4 or
+3.3 and drops off as you move further away from those versions. Python
+3.6 changes things drastically by using word codes rather than byte
+codes. That has been addressed, but then it also changes function call
+opcodes and its semantics and has more problems with control flow than
+3.5 has.
+
+Currently not all Python magic numbers are supported. Specifically in
+some versions of Python, notably Python 3.6, the magic number has
+changes several times within a version. We support only the released
+magic. There are also customized Python interpreters, notably Dropbox,
+which use their own magic and encrypt bytcode. With the exception of
+the Dropbox's old Python 2.5 interpreter this kind of thing is not
+handled.
+
+We also don't handle PJOrion_ obfuscated code. For that try: PJOrion
+Deobfuscator_ to unscramble the bytecode to get valid bytecode before
+trying this tool.
+
+Handling pathologically long lists of expressions or statements is
+slow.
+
+
+There is lots to do, so please dig in and help.
