v2.9.0

Release Notes

This release brings a few interesting features, such as support for the @stream directive, alongside a new batch of performance improvements. Note that the @stream addition caused some changes that impact the @defer directive usage as well.

The QuickAdapter now depends on the long-awaited stable 3.0.x version of zio-http, which means no more binary compatibility issues between releases.

Finally, one noticeable change is that we are now using jsoniter internally to encode and decode GraphQL requests and responses, which means you don't need to depend and import one of the tapir-json libraries anymore.
