v2.9.5

1. Improved banner generator:

   • Ability to choose whether to show division or rank as front row in the right side.
   • Accept custom background image defined by banner_background_url in config.
   • Accept custom background opacity defined by banner_background_opacity in config.

2. Added support to modifying request object through middleware

   • Modified standard return value of request middleware: Originally only an optional response is returned. Currently either None or a tuple of (request, response) has to be returned. If response is not None, then the response will be returned directly. Otherwise, the request will be processed normally.

3. Added discord_request middleware to manipulate data sent to Discord

   • The method, url and data in requests will be passed to discord_message middleware, and the middleware must return a valid data which will be sent to Discord.
   • If there are multiple middlewares present, the data will be updated by earlier ones in the list, and the updated data will be passed to later ones.
   • The middleware function must be synchronous and asynchronous functions will be not executed.
