All themes are now converted to Core versions, and old ones are no longer updated. xScape Theme Framework will not be available as standalone update, it will be always updated with xScape Core theme. And now, we have a lot core changes to the way xScape is loaded.
Since a lot of admin side operations done by the theme are done through AJAX, all those operations are now separated into own file that is loaded only if the WordPress is processing AJAX calls. Because of this a lot of code is moved from main settings and admin classes into new AJAX class. Main admin and theme classes are optimized and all the code needed only for the theme panels are moved into separate GUI class that will handle all panels rendering.
With all these changes, theme now allocates about 20% less memory than before. Memory usage can be even lower if you disable some of the modules or widgets if you don’t use. Depending on what xScape modules and widgets you have active, theme can use even less memory. All modules and widgets make up for 20% of total resource usage for xScape. Used memory can now go from 4MB to 7MB depending on active modules and widgets. Most memory is used on the xScape panels due to the loading of panles GUI, on other areas, xScape uses much less memory and same goes for the front end. This is very conservative use compared to other theme frameworks available on the market.
Work on the framework and new themes will resume by the end of January. Until them, if you notice any problems with new framework, please report them as soon as possible in the comments or in the forums.
