This major release was not planned, since I wanted to work on 4.0 version. But, there were many things I wanted to do ahead of that one, and to also have support for the modules, and because of all that GD CPT Tools 3.8 is very important release with fairly long changelog.
WordPress Navigation Menus are expanded with new meta box for adding post types archives links into the menus. It is simple to use, selected post types from list and add them to the menu. You can modify each menu item later. Only public post types that have archives will be in the list.
With first module coming out soon (in October), plugin is expanded with hooks to allow modules to modify and add features, support own controls. Post types and taxonomies editors support new modules panel for additional options modules might need to add. In the same time, several bugs with interface are fixed. Saving post type and taxonomies has additional validation to check and cleanup values entered for query variable and custom slugs.
Custom fields got several major improvements. Text field now can use regular expressions or masks for data entering, with several predefined regexes and masks. Each custom field has settings for limiting access to custom field values editing to specified user roles or users with specified capabilities. Same thing is done for whole meta boxes. Also, filters are added to control access from code.
Plugin also includes latest jQueryUI 1.8.23 and new gdr2 library 2.7.9.
Due to the number of major changes, please test this version and let me know if there are any issues. I will get to fixing them as soon as possible (as always).
