+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.

 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.
