Lightweight render pipeline with post processing stack?

Hello. My post processing stack does not work with my lightweight render pipeline when the pipeline asset is applied under graphics settings, is there a way to get these to work together? also im running unity 2018.1.0f2 and under my package manager where I download the pipeline it says the version is 1.1.5-preview, what does the preview mean? is the pipeline in a form of open beta?

Thank you

 

See this thread: https://forum.unity.com/threads/post-processing-for-lightweight-pipeline.520668/
When you create a new project using the Lightweight template, there should be a Sample Scene + content.

As for "Preview": Most of the rendering pipelines, including the LWRP, are listed as Preview because they're not final/production-ready yet.

Thank you I appreciate the response and links, has unity said when the pipeline will be production ready?
