Announcing YUI Compressor 2.4.7

By YUI TeamNovember 14, 2011

We're pleased to announce the immediate availability of version 2.4.7 of the YUI Compressor. This version contains fixes to Compressor's handling of CSS minification in a couple of core areas. It does not contain any JS Compression changes.

CSS minification

  • Fixed data URL handling, so that it large data URL values don't crash or slow down CSS Compression.
  • Fixed hex color value compression logic (#AABBCC -> #abc), so that the Compressor doesn't inadvertently compress ID selectors (#AddressBook {...}) .
  • All Java CSS Compressor fixes have been ported to the JS Compressor.
  • All fixes are backed up by unit tests.


YUI Compressor 2.4.7 is available for immediate download. Feel free to help us out by filing a bug or feature request, contributing code or tests or joining the conversation.
