Release 2.9.0

This release adds caching of compiled graphs inside the Scipy optimizer, and adds support for returning loss history. It also adds supports for Python 3.11.

Major Features and Improvements

• Support returning loss history with Scipy optimizer.
• Scipy minimize wrapper caches compiled graphs and re-uses them if called with the same arguments. This functionality can be disabled by setting the new compile_cache_size argument to 0.

Bug Fixes and Other Changes

• Support and test with Python 3.11
• Test against a 'production' environment (in addition to 'min' and 'max' environments).
