Major Release
This major release introduces substantial changes, some of which are breaking, to Prebid Server that warrants extra attention and thorough vetting from host companies prior to deployment.
Host Upgrade Path
TODO - if using video endpoint it needs to be re-enabled
TODO - if using HTTP fetcher legacy query param format, it needs to be re-enabled as RFC 3986 is now the default
TODO - if using embedded Ubuntu root certificates you will need to switch to system certificates
TODO - There are a few minor metric and error message adjustments
