Dean Edwards has released Packer version 3.0, that allows and is one of the top utilities to squeeze your JavaScript.

  • respects Microsoft conditional comments
  • new option to shrink variable and argument identifiers
  • removed the special chars feature (except the ;;; feature which people seem to like)
  • some bug fixes:
    • packer no longer closes spaces between the +/- operators so code like this is safe: c = a++ +b;
    • the throw"error"} bug that affected Safari (this is a Safari bug really but packer gets around it)
    • the __proto__ bug for Mozilla browsers (this only affected the online version of packer)
    • a minor parsing bug affecting the detection of regular expressions
  • simplified the user interface

Dean also had some fun sniffing browsers and came up with the short test.

Check out Packer version 3.
