This is the biggest change:<p>> <a href="http://fishshell.com/release_notes.html" rel="nofollow">http://fishshell.com/release_notes.html</a><p>> When tab-completing a file, fish will first attempt prefix matches (foo matches foobar), then substring matches (ooba matches foobar), and lastly subsequence matches (fbr matches foobar). For example, in a directory with files foo1.txt, foo2.txt, foo3.txt…, you can type only the numeric part and hit tab to fill in the rest.<p>This is really brilliant! I always wanted that (without knowing it).
