Version 22.3.0

Features

  • #2347 API for multi-application server

  • sanic-routing#58 Default matching on non-empty strings only, and new strorempty pattern type
    • 🚨 BREAKING CHANGE: Previously a route with a dynamic string parameter (/<foo> or /<foo:str>) would match on any string, including empty strings. It will now only match a non-empty string. To retain the old behavior, you should use the new parameter type: /<foo:strorempty>.

  • #2381 Fix newly assigned None in task registry

  • #2362 22.3 Deprecations and changes
    1. debug=True and --debug do NOT automatically run auto_reload
    2. Default error render is with plain text (browsers still get HTML by default because auto looks at headers)

    4. ErrorHandler.lookup requires two positional args
    5. Unused websocket protocol args removed
  • #2344 Deprecate loading of lowercase environment variables
