To best help the community plan, to best forward information of breaking changes, to give a better idea of when things will happen, we started to make public the Release Schedule for Arduino Core for ESP32, along the Component for ESP-IDF. We are using GH Wiki for that.

Of course, all information listed there are based on a best effort and best case scenarios. Well, even if we need to move dates around, it is still better to be informed than not. The schedule will be updated at every release or when dates change.
