Probably automatic, we were not contacted ro confirm or infirm.
I've seen it happen on other threads when there are no version update for too much time. In JONT's case, the abandoned tag makes no real sense.
JONT is completed, not abandoned. Similar to Skyrim; content, bugfixes and balance patches keep being added, but you wouldn't call it abandoned in between the gap of updates that occur 13 years after the initial, complete release.
In our case, the constantly updated alpha version is playable by all, and active devs reply on the thread every day.
And stable version release is right around the corner, when ImperatorAugustus finishes his bugtesting 0 start playthrough, and that no bug/balance report have been sent to us for several days after that.
