# Release History

## 1.0.0b10 (Unreleased)

### Features Added

- Enabled the use of the `context` keyword argument for passing in context headers of a parent span. This will be the parent context used when creating the span. ([#30411](https://github.com/Azure/azure-sdk-for-python/pull/30411))

### Other Changes

- Python 2.7 is no longer supported. Please use Python version 3.7 or later.
- Nested internal spans are now suppressed with just the outermost internal span being recorded. Nested client spans will be children of the outermost span. ([#29616](https://github.com/Azure/azure-sdk-for-python/pull/29616))
- When client spans are created, a flag is set to indicate that automatic HTTP instrumentation should be suppressed. Since azure-core already instruments HTTP calls, this prevents duplicate spans from being produced. ([#29616](https://github.com/Azure/azure-sdk-for-python/pull/29616))
- Schema URL is now set on the tracer's instrumentation scope. ([#30014](https://github.com/Azure/azure-sdk-for-python/pull/30014))
- Minimum `opentelemetry-api` dependency bumped to `1.12.0`.
- Minimum `azure-core` dependency bumped to `1.24.0`.
