## Version 7.0.6 (2021091400)
**Bugfixes:**
* Fixed a bug where courseid was always set to 0 when adding new booking options.

## Version 7.0.5 (2021091000)
**New features:**
* New cohort and group subscription (within "Book other users") for booking options.
* Unique option names
  When using CSV import for booking options, option names need to be unique. If there are multiple options with the
  same name, a unique key will be added internally to the option name. In the plugin settings, you can now define the
  separator (default: #?#) between the option name and the key.

**New PRO features:**
* Availability info texts for booking places and waiting list
  Instead of showing the numbers of available booking places and waiting list places, you can now go to the plugin
  config and activate availability info texts (you can activate them separately for available places and waiting list
  places). You can also define a percentage for the places low message. If the available booking places reach or get
  below this percentage a booking places low message will be shown. (You need to activate this feature with a PRO
  license.)

**New PRO features:**
* Global mail templates - each booking instance can define its source of mail templates:
  (Option 1) From within the booking instance (default)
  (Option 2) Use global mail templates defined in plugin settings
  This feature allows you to define global mail templates within the plugin config and use them within every booking
  instance on the whole platform. (You need to activate this feature with a PRO license.)

  days before the event start to notify teachers and to new placeholders to include in the template:

  with a PRO license.)
