[$] A bunch of releases from the Pallets projects

May 11 marked a new major release for the Python-based Flask web
microframework project, but Flask 2.0
was only part of the story. While the framework may be the most visible
piece, it is one of a small handful of cooperating libraries that provide
solutions for various web-development tasks; all are incorporated into the Pallets projects organization. For
the first time, all
six libraries that make up Pallets were released at the same time and
each had a new major version number. In part, that new major version
indicated that Python 2 support was being left behind, but there is
plenty more that went into the coordinated release.
