The latest stable version of Meta Box is now available for download and update from This minor version has a big improvement for file and image upload field, which makes them now cloneable. It also adds new styles for cloning fields and various improvements for code quality.


Rewrite file_advanced and image_advanced fields

The biggest change in this version of Meta Box is the completed rewrite of file_advanced and image_advanced fields. These fields are now sharing the same code base (99% are the same) which reduce the duplicated code and duplicated logic a lot. But the most important thing in this rewrite is these fields now are cloneable which make them act consistently like other fields.

There will be no changes in the appearance, so users won’t notice the change. All the things are handed automatically in the background.

Also there’s one note: for being cloneable, these fields lost their auto save ability, which means to save the selected (or uploaded) files/images, you have to click Publish button. This is not a big deal, because all other fields are saved in the same way.

Better way to translate and update language packs

The second big change in this version is Meta Box is fully migrated to, which lets us to translate the plugin in an easy way. The plugin now uses the auto update mechanism of WordPress to update language packs.
