+#### Enhancements

+- Send new request headers for metrics and troubleshooting with the `set_context`
+  method on the `analyzer` module and within the core API request libs.
+- Abstract package version into a distinct file to consolidate updates and ensure
+  consistency across docs and pypi. Add `get_version` method to `analyzer` module
+  for easy access to the current version number.
+
+
+#### Bug Fixes
