+3.3.4 2019-05-19 Fleetwood at 65
+================================
+
+Most of the work in this is release is thanks to x0ret.
+
+- Major work was done by x0ret to correct function signatures and include annotation types
+- Handle Python 3.6 STORE_ANNOTATION [#58](https://github.com/rocky/python-uncompyle6/issues/58)
+- Friendlier assembly output
+- `LOAD_CONST` replaced by `LOAD_STR` where appropriate to simplify parsing and improve clarity
+- remove unneeded parenthesis in a generator expression when it is the single argument to the function [#247](https://github.com/rocky/python-uncompyle6/issues/246)
+- Bug in noting an async function [#246](https://github.com/rocky/python-uncompyle6/issues/246)
+- Handle unicode docstrings and fix docstring bugs [#241](https://github.com/rocky/python-uncompyle6/issues/241)
+- Add short option -T as an alternate for --tree+
+- Some grammar cleanup
+
+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`
+

+3.3.2 2019-05-03 Better Friday
+==============================
+
+As before, lots of decomplation bugs fixed. The focus has primarily
+been on Python 3.6. We can now parse the entire 3.6.8 Python library
+and verify that without an error. The same is true for 3.5.8. A number
+of the bugs fixed though are not contained to these versions. In fact
+some span back as far as 2.x
+
+But as before, many more remain in the 3.7 and 3.8 range which will
+get addressed in future releases
+
+Pypy 3.6 support was started. Pypy 3.x detection fixed (via xdis)
+
+3.3.1 2019-04-19 Good Friday
+==========================
+
+Lots of decomplation bugs, especially in the 3.x series fixed. Don't worry though, many more remain.
+
+* Add annotation return values in 3.6+
+* Fix 3.6+ lambda parameter handling decompilation
+* Fix 3.7+ chained comparison decompilation
+* split out semantic-action customization into more separate files
+* Add 3.8 try/else
+* Fix 2.7 generator decompilation
+* Fix some parser failures fixes in 3.4+ using test_pyenvlib
+* Add more run tests
+
+3.3.0 2019-04-14 Holy Week
+==========================

+* First cut at Python 3.8 (many bugs remain)
+* Reinstate -c | --compile (compile before disassembly) option
