NOTE: There are a few big changes to be aware of. First of all, per-zoom layouts have been removed. On startup, Cocoon will ask which layout you want to keep for home and your manual folders. You can still zoom between layouts, but only one will be editable now.
Also, if you update via an APK, Cocoon will ask to Optimise itself. This will reinstall Cocoon with its baseline profile to compile the most used code ahead of time to avoid stutters (if you choose not to, Android will do this while it's night, idle and charging, so it's recommended to Optimise if asked).
Cocoon also has a new in-app updater which will do this for you when it updates, so we recommend using the new auto-updater rather than Obtanium to skip the optimisation step each update.
