SSL connections to New Relic are now mandatory

Prior to this version, using an SSL connection to New Relic was the default behavior. SSL connections are now enforced (not overrideable).


  • Add automatic tracing of AIOHTTP 3 middleware

    In addition to the old-style middleware previously supported, the AIOHTTP 3 style middleware is now automatically traced as part of the AIOHTTP instrumentation package.
