v1.1.0

Enhancements

• Codebase has been revamped to be more modular and object-oriented.
• New filter, "cmb_{$element}_attributes" for modifying an element's attributes.
• Every field now supports an attributes parameter that takes an array of attributes. Read more.
• Removed cmb_std_filter in favor of cmb_default_filter. THIS IS A BREAKING CHANGE
• Better handling of labels in sidebar. They are now placed on top of the input rather than adjacent.
• Added i18n compatibility to text_money. props @ArchCarrier
• New helper functions: cmb_get_field and cmb_get_field_value for getting access to CMB's field object and/or value.
• New JavaScript events, cmb_add_row and cmb_remove_row for hooking in and manipulating the new row's data.
• New filter, cmb_localized_data, for modifiying localized data passed to the CMB JS.

Bug Fixes

v1.0.2

Enhancements

• Change the way the 'cmb_validate_{$field['type']}' filter works.
  It is now passed a null value vs saved value. If null is returned, default sanitization will follow. THIS IS A BREAKING CHANGE. If you're already using this filter, take note.
• All field types that take an option array have been simplified to take key => value pairs (vs array( 'name' => 'value', 'value' => 'key', )). This effects the 'select', 'radio', 'radio_inline' field types. The 'multicheck' field type was already using the key => value format. Backwards compatibility has been maintained for those using the older style.
• Added default value option for taxonomy_select field type. props @darlantc
• Added option to specify image preview size for file_list field type. props @IgorCode
• Updated file_list images to be displayed horizontally instead of vertically. props @IgorCode
• Use get_the_terms where possible since the data is cached.

• Replaced __DIR__, as dirname( __FILE__ ) is easier to maintain back-compatibility.
• Fixed missing table styling on new posts. @mustardBees
• Fix undeclared JS variable. @veelen
• Fix file_list errors when removing all files and saving.
• Set correct object_id to be used later in cmb_show_on filter. @lauravaq
• Fix sanitization recursion memeory issues.

Bug Fixes

• Fixed wysiwyg editor button padding. props @corvannoorloos
• A few php < 5.3 errors were addressed.
• Fields with quotation marks no longer break the input/textarea fields.
• metaboxes for Attachment pages now save correctly. Thanks @nciske for reporting.
• Occasionally fields wouldn't save because of the admin show_on filter.
• Smaller images loaded to the file field type will no longer be blown up larger than their dimensions.

Enhancements

• Now works with option pages and site settings. (view example in wiki)
• two filters to override the setting and getting of options, cmb_override_option_get_$option_key and cmb_override_option_save_$option_key respectively. Handy for using plugins like WP Large Options (also here).
• Improved styling on taxonomy (tease) and options pages and for new 3.8 admin UI.
• New sanitization class to sanitize data when saved.
• New callback field parameter, sanitization_cb, for performing your own sanitization.
• new cmb_Meta_Box_types::esc() method that handles escaping data for display.
