Akka HTTP 10.2.2 released

Dear hakkers,

We are happy to announce the 10.2.2 release of Akka HTTP. This release is the second update in the 10.2.x series of Akka HTTP.

Changes since 10.2.1

For a full overview you can also see the 10.2.2 milestone.
Notably, we have made various improvements to the HTTP/2 server support
while we continue to prepare for providing HTTP/2 support at the client as
well.

As of this version, it is no longer strictly necessary to depend no a separate
‘akka-http2-support’ artifact to get HTTP/2 support in Akka HTTP. We will
continue to publish an empty artifact with that name to make it easy to
upgrade, however.
