OS Calendar 8.0 is now fully compatible with Joomla 4

What new in OS Calendar 6.0: Room is not mandatory now

In previous versions, when you use OS Calendar, you must create Rooms for Properties (of OS Property component). And then, you should setup Price, Availability status for those rooms before customer can make the booking on rooms at front-end of component. This work is quite suitable with Hotel or Rooms renting, but if you are owner of Apartments, Villas .etc, you won't able to use OS Calendar, because you can't create rooms for your Apartments, Villas .. and customers won't rent one several rooms of one apartment or villas.

Understand it, we decide to improve OS Calendar, to make it to suitable with Rental properties. Now, if you go to Configuration page of OS Calendar, you will see the configure option Enable Room. If you select this field Yes, you will need to create Rooms for properties as previous versions, select No if you want to be able to setup Price, Availability status for properties (of OS Property component).

As you know, there is the big improvement on OS Calendar 6.0 so we encourage you to download latest OS Calendar version to get new improvement. And please update the languages (through Translation tool at Back-end of OS Calendar ) if you are using different language than English.

To Update OS Calendar 6.0, please install

1. com_calendar.zip

2. update language files if you are using more language than English
