-# ATTENTION BREAKING UPDATE!!
-
-> The latest `main` branch has completely changed the way this app used to run.
-> The main reason being trying to address some security concerns and make the whole application work
-> across multiple platform without too much trouble.
->
-> If you came here due to this change trying to figure out why your app stopped working you have two options:
->
-> 1 - Update your `docker-compose.yml` with the new one provided within this readme (or just copy [docker-compose.yml](docker-compose.yml))
->
-> 2 - Keep your `docker-compose.yml` file as it is and use the legacy tag in the image `image: ghcr.io/fccview/cronmaster:legacy`. However bear in mind this will not be supported going forward, any issue regarding the legacy tag will be ignored and I will only support the main branch. Feel free to fork that specific branch in case you want to work on it yourself :)
