The Road to Full Release
The post says Harp Isles is heading into full release, and that the beta will get a proper ending rather than switching off: goals to complete before it closes, and an achievement that carries into the full release as proof the player was there from the start. It also says a dedicated suggestions thread is being opened so players can shape what that ending looks like.
It is explicit that no new content is coming to the beta — “there won't be any new content added to the beta from here on out” — because the team's time is going into the full game instead. The beta stays open and joinable in the meantime.
On what the full release is: “This isn't a content update. It's a rebuild.” The post says a large part of the game's systems are being recoded from the ground up, and that the result should feel like a new game while keeping its setting and creatures. No feature list and no date are attached.
What it means for you: your unlocked creatures carry over, the beta keeps running without new content, and there is nothing to schedule around yet.
