Version 3.7.7

Changed

• Added warning message to runserver explaining the usage in development mode only.
• Lazy evaluate the environment variable for the settings import. This relaxes the restraints on the import order.
  You can e.g. import lilya settings before adjusting ESMERALD_SETTINGS_MODULE as long as you don't access the settings object.

Fixed

• Typing for the handlers (@get, @post...) that was causing mypy to give false positives.
• Documentation examples.
• Documentation references.
• encoders ENCODER_TYPES was a static snapshot of a ContextVar. Leverage a TransparentCage instead.
