[4.0.0] - January 12th, 2022
New Features
Add a set of new APIs for overriding and managing user-level flag, experiment and delivery rule decisions. These methods can be used for QA and automated testing purposes. They are an extension of the OptimizelyUserContext interface ([#361](https://github.com/optimizely/python-sdk/pull/361), [#365](https://github.com/optimizely/python-sdk/pull/365), [#369](https://github.com/optimizely/python-sdk/pull/369)):
- setForcedDecision
- getForcedDecision
- removeForcedDecision
- removeAllForcedDecisions
For details, refer to our documentation pages: [OptimizelyUserContext](https://docs.developers.optimizely.com/full-stack/v4.0/docs/optimizelyusercontext-python) and [Forced Decision methods](https://docs.developers.optimizely.com/full-stack/v4.0/docs/forced-decision-methods-python).
Breaking Changes:
- Support for `Python v3.4` has been dropped as of this release due to a security vulnerability with `PyYAML <v5.4`.>
- We no longer support `Python v2.7, v3.5, and v3.6` including `PyPy` as of this release. ([#377](https://github.com/optimizely/python-sdk/pull/373))
- We now support `Python v3.7 and above` including `PyPy3`.
