Documentation included with TGB is older

I had downloaded TGB again after I had re-installed my OS and noticed that the documentation is older than what is currently on the site. I was wondering if we would see an update to the offline version soon. I know this falls on a low priority since you can get to it from the website, but having it offline would really help if I need to read a portion of it while I am riding in a car or at a house without a good Internet connection
Thanks.
