Python 3.10 is proceeding apace; everything looks to be on
track for the final release, which is expected on
October 4. The beta releases started
in early May, with the first of those marking the feature-freeze for this version of
the language. There are a number of interesting changes that are coming with
Python 3.10, including what is perhaps the “headline feature”:
structural pattern matching.
