Update Python client CHANGELOG

rzats commented 1 month ago

Closes #1432.

Summary:

Updates the Python client's changelog to include items from previous releases.

Also includes a few currently pending changes. These can be omitted if we want to update the CHANGELOG right away; otherwise the date will need to be updated during the next release.

Prerequisites:

[x] Unless it is a documentation hotfix it should be merged against the dev branch
[x] Branch is up-to-date with the branch to be merged with, i.e. dev
[x] Build is successful
[x] Code is cleaned up and formatted
