Master is now 0.4.0, with send/receive pipelines and no transforms. 
How to update if you are not using a lot of low-level mechanics, you need to make only few changes:
– import `respond` function from different (response) package
– use `call.receive` instead of `call.request.receive`
– call-level interceptors are now using `PipelineContext&lt;Unit&gt;` instead of `PipelineContext&lt;ApplicationCall&gt;`, `call` is a property of a context, might need updating some code.

If you are using low-level stuff, ask me specific questions :slightly_smiling_face:

Now, with send/receive pipelines, road is paved to proper serialisation, content negotiation, REST and such. `GsonSupport` is an experimental feature that uses it. We will be working on it during next sprint.
