There is a new version of the WinUAE Help file available as of now, which is 2.2.15. You may grab the updated version in our downloads section, as usual.
Also, in a rare case of promised and actually completed some work: the online version of the WinUAE Help is now up-to-date with the latest development! There have been a lot of changes going on in an attempt to vastly improve the content quality. This will ultimately result in a version 3.0 for the file. In the meantime, keep track of progress at winuaehelp.vware.at!
Winuae 4.1.0 is now out and available from http://www.winuae.net/
I have made a few small changes to WinUAE help 2.2.17 for GUI and the FAQ. Please see Github.com site for latest version.
