v0.7.0

0.7.0

Added

• Stability status added to the documentation.
• Support OTEL_LOG_LEVEL to configure SDK logging level.
• Fallback for the service name. If the service name is not configured, the automatic instrumentation uses the entry assembly name instead, only falling back to the process name in case of an error. If the application uses .NET Framework and is hosted on IIS, the service name is determined using SiteName/ApplicationVirtualPath.
