Better overview over released, planned and considered features

It would be nice if there would be a better overview over which features got released and in which version, as well as which features are planned for a certain version and which features are under consideration, that for each category separately so that we have a better overview and can vote features that are under consideration up to show our interest. Something like Unity does for their roadmap. It would be nice to have such a proper roadmap for Minecraft as well, it would make it much easier to get an overview on what is worked on, and so on, so we as a community, ask less of the same questions.
