This is an unofficial Magento 2 Roadmap. The idea is to have a single point where you can find new stuff that is planned for Magento 2. This should make it easier for everyone of us dealing with Magento 2 to plan ahead.

Magento announced an official roadmap on the 21.10.2021: see https://devdocs.magento.com/release/roadmap.html
