Gregory's Server20.0 has now been released on googles play store, and naturally you can download the APK from our repo if you don't want to use the store. If you want to automate that, try out obtanium.
Please upload any edits before upgrading, if you don't you will not be able to load previous edits. You can recover from that with the auto-saved changes, but you can completely avoid the upset by uploading first.
