Hey Just_Kris,
AHITR gets updated monthly with smaller updates, sometimes the updates can be beefy but generally the updates are smaller. This was a decision that was voted for by Patrons over on Patreon (where they choose either smaller but monthly updates or larger updates with a longer release window).
Around the time period you mentioned, we would've have pushed the April's Fool update and anniversary update/celebration, which iirc, was v0.7.8 and we are now currently on 7.14, so its been a bit more than 0.2 updates.
You also mentioned you haven't downloaded any version of the game recently, I'd suggest doing so and diving into the content you've been missing if you are truly curious to what's been added.
Appreciate you dropping by all the same and hope you enjoy if you decide to dive in!
