-================
-
-- Correct assert{,2} transforms Fixes #289

-- Use newer xdis to better track Python 3.8.0

-3.4.0 2019-08-24 Totoro
-=======================
-
-The main change is to add a tree-transformation phase. This simplifies the

-`assert`, and many `if ..: else if ...` into `if ... elif ..`
-
-Use options `--show=before` and `--show=after` to see the before the tree transformation phase and after the tree transformation phase.

-- Fix issue #275, #283 (process to fix this bug is documented on wiki), #284
-- blacken more code
-- CircleCI adjustments for a changing CircleCi
-- Require more recent `xdis` for Python 3.8

-Verification
-------------
+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.
 
-In older versions of Python it was possible to verify bytecode by
-decompiling bytecode, and then compiling using the Python interpreter
-for that bytecode version. Having done this the bytecode produced
-could be compared with the original bytecode. However as Python's code
-generation got better, this no longer was feasible.
+You can also cross compare the results with pycdc_ . Since they work
+differently, bugs here often aren't in that, and vice versa.
 
-If you want Python syntax verification of the correctness of the
-decompilation process, add the :code:`--syntax-verify` option. However since
-Python syntax changes, you should use this option if the bytecode is
-the right bytecode for the Python interpreter that will be checking
-the syntax.
-
-You can also cross compare the results with another python decompiler
-like pycdc_ . Since they work differently, bugs here often aren't in
-that, and vice versa.

-There is an interesting class of these programs that is readily

-test themselves. Our test suite includes these.

-And Python comes with another a set of programs like this: its test
