Hi guys,
Here is the guide: http://www.swiftideas.com/knowledgebase/upgrading-to-atelier-cardinal/
Same for Neighborhood as is with Dante.
In terms of what’s new, we’ve spent a huge amount of time developing new performance functionality, which we call “Swift SmartScript”. We detect the contents of a page when you save it, and store meta values based on the content. We then use these values to remove unnecessary scripts from the page, including from selected 3rd party plugins. We found in most tests this removed upwards of 60% of scripts from the page, and greatly increased load times.
This does require each page to be saved once the functionality is enabled, but there are bulk save plugins you can download.
We’ve also added built in stylesheet minification.
In terms of functionality, we’ve worked on greatly improving the mobile experience, especially in terms of shop browsing, with layout options, mobile filters, etc. We’ve also added an option to provide a different logo for the mobile header.
There is a new slideout menu option, header aux builder, newsletter bar, global header banner, row top/bottom slant styling, and an all round slicker design.
