+3.4.0 2019-08-24 Totoro
+=======================
+
+The main change is to add a tree-transformation phase. This simplifies the
+code a little and allows us to turn `if ...: raise AssertionError` into
+`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.
+
+Most of the heavy lifting for this was done by x0ret.
+
+Other changes:
+
+- 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

+- Handle annotation arguments in Python 3.x
+- Fix _vararg_ and function signatures in 3.x
+- Some 3.x < 3.6 `while` (1)/`if` fixes &mdash; others remain
+- Start reinstating `else if` -> `elif`
+- `LOAD_CONST` -> `LOAD_CODE` where appropriate
+- option `--weak-verify` is now `--syntax-verify`

+3.3.3 2019-05-19 Henry and Lewis
+================================
+
+As before, decomplation bugs fixed. The focus has primarily been on
+Python 3.7. But with this release, releases will be put on hold,as a
+better control-flow detection is worked on . This has been needed for a
+while, and is long overdue. It will probably also take a while to get
+done as good as what we have now.
+
+However this work will be done in a new project
+[decompyle3](https://github.com/rocky/python-decompile3).  In contrast
+to _uncompyle6_ the code will be written assuming a modern Python 3,
+e.g. 3.7. It is originally intended to decompile Python version 3.7
+and greater.
+
+* A number of Python 3.7+ chained comparisons were fixed
+* Revise Python 3.6ish format string handling
+* Go over operator precedence, e.g. for AST `IfExp`
