This release focuses on modernizing the stack, and introduces many new

features and some new modules.
The release drops Python 2.7 and adds support for 3.7 - 3.11. Several of

our dependencies have been updated accordingly.
There's new support for secrets and token generation, encrypted caching,

and enhanced API tokens with expiration/deprecation/invalidation.
Improvements have been made to the API and extension capabilities.
New unit testing capabilities, form fields, and condition choices have

been added.
This change documents all these improvements in preparation for the

upcoming 3.0 release.

Built the docs. Checked for spelling errors, build errors, and bad links.
