2.2.0

Highlight

Product Review service was added to the demo, bringing GenAI-powered summaries.
The summaries can be locally simulated (useful to test spans with GenAI semantic conventions), but it can also be used with OpenAI.

Check out the documentation to learn how to configure it: https://opentelemetry.io/docs/demo/services/product-reviews/

Caution

Be aware that when using the Product Review service with your OpenAI token, this will cost you real tokens.
