If you're the lucky (debatable) owner of a Verizon Galaxy Tab 7.7 or LG Lucid, good news - you're about to get an OTA update! Verizon just posted new update docs on its support site for both devices.
The Tab 7.7's update is about as minor as you can get, though, offering reduced electrical consumption when charging... while powered off. We're guessing that's not what this update is actually about though. The Tab 7.7 was one of a handful of American devices affected by the Samsung Exynos kernel exploit (it runs an Exynos 4210 chipset), and my money's on this update (build LP1) addressing that issue.
