Get ready for release 3.7.2

Hopefully by using first_child() we have something more robust now.

+3.7.2: 2020-6-27
+================
+
+* 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
+
+
+
+3.7.1: 2020-6-12 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
+
+3.7.0: 2020-5-19 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
+
+
+3.6.7: 2020-4-27 xdis again
+===========================
+
+More upheaval in xdis which we need to track here.
+
+3.6.6: 2020-4-20 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
+
+
+3.6.5: 2020-4-1 April Fool
+==========================
+
+Back port some of the changes in decompile3 here which mostly helps 3.7 and 3.8 decompilation, although this may also help 3.6ish versions too.
+
+- Handle nested `async for in for...`  and better async comprehension detection via `xdis`.  Still more work is needed.
+- include token number in listings when `-g` and there is a parser error
+- remove unneeded `Makefile`s now that remake 4.3+1.5dbg is a thing that has `-c`
+- Bug in finding annotations in functions with docstrings
+- Fix bug found by 2.4 sre_parse.py testing
+- Fix `transform` module's  `ifelseif` bugs
+- Fix bug in 3.0 name module detection
+- Fix docstring detection
+

 * https://github.com/wibiti/uncompyle2 : supports Python 2.7 only, but does that fairly well. There are situations where :code:`uncompyle6` results are incorrect while :code:`uncompyle2` results are not, but more often uncompyle6 is correct when uncompyle2 is not. Because :code:`uncompyle6` adheres to accuracy over idiomatic Python, :code:`uncompyle2` can produce more natural-looking code when it is correct. Currently :code:`uncompyle2` is lightly maintained.
