The A-Shell documentation is kept very up to date. Jack meticulously documents every change/addition/improvement to A-Shell, writes the text version of ashdevnotes, and posts it with new versions of the software. As mentioned above, you can always find the up-to-the-second release notes with the latest versions of A-Shell.
Within hours or a day or two, Ty converts the text version of ashdevnotes into an HTML version, and posts it in the same place. All the new or changed material from ashdevnotes is incorporated immediately into the applicable manual(s) of the main A-Shell doc set, and those docs are immediately published and available.
To read the latest versions of any A-Shell documentation, simply go to the download...documents page and click on the doc that interests you.
