Ubuntu Core Release Cycle

Hi there,

Got a question for the release cycle for Ubuntu Core. Ubuntu versions got the release cycle, https://ubuntu.com/about/release-cycle, and Ubuntu Core images are based on Ubuntu images. I think Ubuntu Core follows the release cycle but may postpone a bit for release and security audits, etc. Is there a page I can refer to have some ideas around how the release cycle looks like for Ubuntu Core in a long run? After core18 images have been deployed on site, what upgrade path would be? How will core18 image be upgraded to core20? The pc-kernel snap can be upgraded. Can the gadget snap be upgraded? I guess in order to do it, that would be a hack in the snapd service which is against the security design of Ubuntu Core.
