 CHANGES
 
+1.1.0 (Feb 27 2026)
+- Split SDK 10.5.1 remains supported. Provider lifecycle events (PROVIDER_READY, PROVIDER_CONFIGURATION_CHANGED, PROVIDER_ERROR) require Split SDK 10.6.0 or later; on 10.5.1 the provider works as before without emitting those events.
+- Provider now emits OpenFeature provider events (PROVIDER_READY, PROVIDER_CONFIGURATION_CHANGED, PROVIDER_ERROR) when Split SDK 10.6+ fires ready/update/timeout. Event details include OpenFeature-friendly metadata (see docs/EVENTS_MAPPING.md).
+
 1.0.0 (Nov 10 2025)
 - BREAKING CHANGE: Passing the SplitClient object to Provider constructor is now only through the initialization context dictionary
 - BREAKING CHANGE: Provider will throw exception when ObjectDetail and ObjectValue evaluation is used, since it will attempt to parse the treatment as a JSON structure.

 This Provider is designed to allow the use of OpenFeature with Split, the platform for controlled rollouts, serving features to your users via the Split feature flag to manage your complete customer experience.
 
 ## Compatibility
-This SDK is compatible with Python 3.9 and higher.
+- Python 3.9 and higher.
+- **Split SDK**: [Split Python SDK](https://github.com/splitio/python-client) **10.5.1 or later**. Provider lifecycle events (PROVIDER_READY, PROVIDER_CONFIGURATION_CHANGED, PROVIDER_ERROR) require **10.6.0 or later**; on 10.5.1 the provider works without emitting those events.
 
 ## Getting started
 
 This package replaces the previous `split-openfeature-provider` Python provider in [Pypi](https://pypi.org/project/split-openfeature-provider/).
 
 ### Pip Installation
 ```python
-pip install split-openfeature-provider==1.0.0
+pip install split-openfeature-provider==1.1.0
 ```
 ### Configure it
 Below is a simple example that describes using the Split Provider. Please see the [OpenFeature Documentation](https://docs.openfeature.dev/docs/reference/concepts/evaluation-api) for details on how to use the OpenFeature SDK.
