Summary of changes between Splunk OTel Python major versions 1 and 2.
44

5+
## Overview
6+
7+
Version 2 of the Splunk Distribution of Opentelemetry Python represents a significant rewrite of the distribution,
8+
including a new build system using Hatch, matching the upstream Opentelemetry Python repository. As the upstream
9+
repository has become more mature since Splunk OTel Python 1.0 was released, version 2 has adopted
10+
a smaller footprint, deferring logic and spec compliance to the upstream project, while making vendor-specific features
11+
available for your convenience to send telemetry to Splunk Observability Cloud.
