VCKit - WPBakery Page Builder addons collection Version History

#### Enhancements

* Ability to use non-repeatable group fields by setting the `'repeatable'` field param to `false` when registering a group field type. Props [marcusbattle](https://github.com/marcusbattle), ([#159](https://github.com/CMB2/CMB2/pull/159)).
* Add and enqeueue a front-end specific CSS file which adds additional styles which are typically covered by wp-admin css. ([#311](https://github.com/CMB2/CMB2/issues/311))
* Better handling of the CMB2 javascript (and CSS) required dependencies array. Dependencies are now only added conditionally based on the field types that are actually visible. ([#136](https://github.com/CMB2/CMB2/issues/136))
* **THIS IS A BREAKING CHANGE:** The `group` field type's `'show_on_cb'` property now receives the `CMB2_Field` object instance as an argument instead of the `CMB2` instance. If you're using the `'show_on_cb'` property for a `group` field, please adjust accordingly. _note: you can still retrieve the `CMB2` instance via the `cmb2_get_metabox` helper function._
* New dynamic hook, `"cmb2_save_{$object_type}_fields_{$this->cmb_id}"`, to complement the existing `"cmb2_save_{$object_type}_fields"` hook.
* German translation provided by Friedhelm Jost.

#### Bug Fixes

* Fix incorrect repeatable group title number. ([#310](https://github.com/CMB2/CMB2/pull/310))
* Fix obscure bug which prevented group field arguments from being passed to the sub-fields (like `show_names` and `context`).
* Fixed occasional issue when adding a group row, the previous row's content would be cloned. ([#257](https://github.com/CMB2/CMB2/pull/257))

#### Bug Fixes

* Fix grouped fields display (first field was being repeated), broken in 2.0.3.
