Version 3.6.7

Added

• before_request and after_request WebSocketGateway handler added.
• before_request and after_request added as default to the settings. This was not required
  as the settings loading system of Esmerald defaults values but this should be added to the settings
  for consistency reasons of the framework.

Changed

• Reverse order on Gateway after_request.

Fixed

• override_settings was not taking into account async functions.
