Extendware’s Magento Minify JS / CSS 1.2.8 was released today and it includes some very important compatibility features. In previous versions of Magento Minify JS / CSS the order of javascript / CSS was not guaranteed to be the same as before the extension is installed. Now, the order that these files are loaded is guaranteed to be the same as before when selecting the “Never”, “Automatic” and “Always” merging modes. “Automatic (aggressive)”, the previous behavior, can still be used and it will merge more files. The order of loaded files only affects some Magento stores, so try the different merge modes and see which one is best for your store.
In addition, this release solved an issue where the merging of pre-minified files and normal files were causing issues with some browsers. Now pre-minified files are not combined with normal files and this solves the browser issues.
