"push updates more frequently." When new content is finished it'll be pushed.
This also means that engine updates will be receiving more internal testing before they go live, so if they get hiccups then they can still be releasing new content to play with.
In fact there's "a bunch of new content that’s pretty much ready to go" as soon as the update is in effect. This also means the "best/most fitting mods" get added more often.
"The programmers have been putting the finishing touches on the system we’re going to use to push updates more frequently. Essentially we’re separating content updates and engine updates. Content updates are going to be pushed to the server as and when content is finished being produced, we’re no longer going to wait on engine updates to push them out at the same time. This also means engine updates will get additional internal testing," Chucklefish.
Apparently full changelogs won't be posted because they'd prefer "players to discover what’s new themselves."
Starbound is available through.
