In this week's release we:

Extended the Mobile Inbox module:

• Before
  • it was only possible to indicate the validity period of the message by a start and end date
• Now
  
  • It is also possible to indicate the validity period relatively
    • e.g.: 7 days starting from the moment the message is sent  

The Mobile Inbox is an optional module from Deployteq, installable in our App Store. It is part of the Mobile Messages-module.
