Change effective on 03 February 2014
The size of dynos included with the dynos and formations endpoints on the API are now suffixed with an “X”. Valid values are “1X”, “2X”, and “PX”.
Old dyno size values (i.e. “1” and “2”) will continue to be respected for the time being.
Heroku Update
Starting November 28th, 2022, free Heroku Dynos, free Heroku Postgres, and free Heroku Data for Redis® will no longer be available. If you have apps using any of these resources, you must upgrade to paid plans by this date to ensure your apps continue to run and to retain your data.
Eligible students can apply for platform credits starting October 3rd, 2022 through our new Heroku for GitHub Students program.
