You can now use LinkAbbrevs by name (not by URL) without a |; ie, instead of writing [[<text>|]], you can just write [[<text>]]. This only happens if <text> wouldn't result in a link to a real page or an external URL if there was no abbreviation.

Thus, one can write [[Google http://www.google.com/]] in the page once, and later write [[Google]], and have it work out.
