Hi PPMC members, New distribution guidelines, that we have been working on for some time, have been published here: https://incubator.apache.org/guides/distribution.html
They contain information on distributing releases on 3rd party platforms including Maven, GitHub, Docker, NPM and PiPy. Note that these are good suggestions on best practice and incubating projects can do things differently, but if you follow these guidelines, you are less likely to have issues on graduation. If you have any questions or feedback on these guidelines, please do so on the Incubator general list. Thanks, Justin
