I think there isn't much of a celebration since people have been messing with JJ2 patches for years now, so that diminishes the excitement. And although bug fixes are awesome, people probably aren't going to make sweeping changes like adding in the capability for mods and stuff. As such, people tend to download and use this stuff, but not get excited since it'd be like being joyous when Warcraft III updates to 1.18c or something.
