Changelog

Enhancements

• Term Meta! As of WordPress 4.4, WordPress will have the ability to use term metadata. CMB2 will work with term meta out of the box. To do so, see the example cmb registration in the yourprefix_register_taxonomy_metabox function in example-functions.php.
• New hooks which hook in after save field action: 'cmb2_save_field' and "cmb2_save_field_{$field_id}". Props wpsmith (#475).
• The “cmb2_sanitize_{$field_type}” hook now runs for every field type (not just custom types) so you can override the sanitization for all field types via a filter.
• CMB2::show_form() is now composed of 3 smaller methods, CMB2::render_form_open(), CMB2::render_field(), CMB2::render_form_close() (#506).
• RTL Style generated. Props @devinsays (#510).
• Properly scope date/time-pickers styling by adding a class to only cmb2 picker instances. (#527)
• Allow per-field overrides for the date/time/color picker options (wiki documentation: Modify Field Date, Time, or Color Picker options)
• Fix some inline documentation issues. Props @jrfnl (#579).
• Include .gitattributes file for excluding development resources when using Composer. Props @benoitchantre (#575, #53).

Bug Fixes

• Fixed issue with 'taxonomy_select' field type where a term which evaluated falsey would not be displayed properly. Props adamcapriola (#477).
