Major changes has been implemented in this version since v0.10.0, including here a list of highlights:

• Implement specification-required error responses for specific scenarios.
  This includes 553 Version Not Supported and 400 Bad Request.
• Implement warnings.
  Warnings emitted through the built-in warnings module will now be added to the JSON response under meta --> warnings.
• Logging.
  The optimade package now has it's own logger based on the built-in logging module. It will both save to file and output to the console using uvicorn's logging formatter, so that it looks nice together with the uvicorn logs.
• Sorting on unknown properties.
• Major documentation overhaul!
• api_hint query parameter.
