typos in release notes for 1.7.1
There are at least a half dozen typos in the release notes. Should I make those changed directly to the Github page (I don't think changing release notes touches any code commits so should be safe).
, since Python client version 1.9.0, we will switch to use `news.rst` so that the release notes can also be accessible from the docs. I copied the content from the previous release to this file. Any typos should be addressed there.
We will keep the old release notes files for anyone who use the old client. Once most users switch to 1.9.0, we will remove the old release notes files.
