I just landed a big reorg of dojo.lang and dojo.string since they were huge. You can get all the gory details on my mailing list post. The low down: dojo.lang and dojo.string have been split up into smaller fragments and, when requested, the most commonly used bits (as defined by yours truly) are pulled in. This may break your code! While we encourage people to take advantage of pulling in less code, the simple way around it is to use dojo.require("dojo.lang.*") and dojo.require("dojo.string.*") in place of dojo.require("dojo.lang") and dojo.require("dojo.string"), respectively. Thank you for your time.
