This new version of the compressor fixes a few bugs and optimizes string concatenations. You can now keep your code nicely formatted by concatenating string literals, but not suffer any performance hit. For example, the following code:
var url = ".../services/rest/" + "?method=flickr.test.echo" + "&format=json" + "&api_key=02b6a73df2c4a33c282f3d02fe5724e3" + "&callback=jsonCallback";
will become (↵ marks a line continuation)
var url = ".../services/rest/↵ ?method=flickr.test.echo&format=json↵ &api_key=02b6a73df2c4a33c282f3d02fe5724e3&callback=jsonCallback";
Also, note that, from now on, all YUI Compressor-related downloads will be done from a separate download page and not directly from this blog.
