# 07.13.2025: Experiments Module in phoenix-client 🧪
{% embed url="https://pypi.org/project/arize-phoenix-client/" %}
**New Features in Phoenix 11.7+:**
* Added a new `experiments` property to both `Client` and `AsyncClient` for invoking experiment workflows.
* Introduced `Experiments` and `AsyncExperiments` classes with `run_experiment` methods supporting **tasks, evaluators, dry-run mode**, and **metadata**.
* Implemented `SyncExecutor` and `AsyncExecutor` classes for **concurrent execution** with built-in **progress bars**.
* Added `RateLimiter` and `AdaptiveTokenBucket` for intelligent handling and throttling of **rate-limit errors**.
**Bug Fixes:**
* Fixed a typo in the `datasets.get_dataset_versions` docstring.
**Enhancements:**
* Introduced a `PhoenixException` base class and **refactored exception imports** for consistency.
* Simplified rate limiter output by replacing `printif` with direct print statements.
