[arch-general] How often kernel26-lts updated?

Just wondering: what's the general policy about how often (and why) kernel26-lts gets updated? I know it's supposed to be a "long-term supported" kernel, making it more appropriate for servers and such. But it seems like it gets updated almost as often as the main kernel26 package. Also, I saw today that it's currently flagged as out of date. What would be the criteria for it being out of date? Is there some upstream release that the lts kernel follows along with? Thanks, DR
