# 2023 June Release

# Calendar

**Double Book Staff but not Resources**
Aesthetic clinics sometimes like to multi task by double booking patients, but treatment rooms are limited in availability, So the rooms should not be double booked. We now support this feature. Just enable it in the **Calendar Preference.**

**Send single SMS for linked appointments**
if a patient has multiple new appointments, notifications will be sent only for 1 of them. Currently it used to be sent each time you made a new appointment for the patient on the same day.
