Although general game updates and content showcases are posted regularly through all beta decay comm channels (email, discord, instagram, twitter etc), detailed Devlog updates can be found on the patreon page:

The Patreon updates reflect much of the work that happens in between each content showcase (In progress features, Images, Concepts, etc).
Therefore, teasers and trailers will continue to be regularly posted while the Patreon development updates will showcase all the nitty-gritty details up to making the polished content showcases.
