Thank you for the summary.  Note that Python reference pages have been
updated even less frequently. [1]  Since Python language and standard
library definitions are now (in 3.x) closely tied to the Unicode
definition, I wonder whether unicodedata.unidata_version should be
more prominently featured in the docs.  (Possibly even included in the
Python CLI banner, but that is probably an overkill.)
