Here’s the beta of the update 3.1 that’ll coming out next week.
The main new features are multiple reservations through the form, possible arrival and departure days (Mon-Sun) can be set per resource, there’s a new filter to set the requirements per time and premium members can install and update modules through the settings directly. Beside of this there were a lot small improvements and bug fixes.

Please report any bugs here in the comments. Take the deepest look into the new system for multiple reservations in the form. You can activate it in the form’s shortcode with the attribute multiple=”popup” or multiple=”full” or just add the shortcode again.

Current beta: 3.1 #11
