Version 3/120430 for Inform 7 6M62
I didn't know of a convenient place to view this on the web, so I made a Standard Rules source web page with a brief table of contents and links to the Inform 7 documentation as appropriate.
The Standard Rules are available within their natural habitat of Inform 7 packages at the Inform 7 Downloads page.
(In hope of avoiding confusion, note that the Standard Rules for Inform 7's 6L02 and 6L38 releases are also internally labelled Version 3/120430, but each is different from the others.)
