compiled LW's show up as "@LimeWire@" with no version number.
The 4.4.1's are somewhat official (for Windows at least), being released by the 'new' method, and it's what people get when they do an official update.
Sam's been really good with the changelogs, but I've been getting my info less offically on this 4.4.1 change.
So, *shrug*, I imagine he'll let us know when he has a chance, but in the meantime--no worries
