Version lifecycle and lifecycle policy of Heroku features were not captured when implemented, meaning we have been caught-out more than once when something is reaching end-of-life/end-of-support (most specifically, Heroku Stack and Play).
Where can I find the lifecycle policies for both, including: version release date, end of support dates (including announcement date), and how to be kept informed of new announcements/upcoming end dates?
Thanks
Have searched through Heroku documentation online, but results haven’t been helpful.
