You can find the current specification of services here. It is currently dated January 2026.

2026-03.5.1

Status labels such as ‘Occupied’ can now be customised and displayed in multiple languages to better meet different requirements.

Greater transparency for display jobs

The traceability of jobs has been improved. It now shows which display or gateway executed a job.

Appointment listings can now be supplemented with customisable headings, for example to distinguish between current and upcoming appointments. This improves readability and structure.

The display of recurring appointments in confirmation emails has been optimised. Appointments are now shown clearly and in chronological order.

Optimised use of recurring appointments and dialogues

2026-03.1.4

Optimised update behaviour without manual cache clearing

The update process has been improved so that new versions are automatically detected and downloaded by the browser. It is no longer necessary to clear the cache manually, meaning that updates occur seamlessly in the background for users.

2026-03.1.1

Improved handling of external resources

The processing and integration of external resources has been optimised, enabling them to be incorporated into bookings more reliably and efficiently.

Cost calculation for bookings

The cost calculation feature has been introduced and now supports various models, such as time-based sliding-scale pricing, optional flat-rate fees, and volume-based and combined calculations.

Flexible rotation of e-paper displays

ePaper displays can now be rotated 90 degrees directly within the software, allowing for more flexible use in a variety of installation scenarios.

Optimising the performance of the map view

The map view has been optimised technically, reducing loading times and making the overall experience smoother.

Revised approval process for services with buffers

The approval process for services with buffer times has been streamlined.

Improved booking conflict logic

The logic for detecting and handling posting conflicts has been revised and now produces more accurate results.

Optimised integration with Microsoft 365 and related resources

Integration with Microsoft 365 has been improved, particularly when working with dependent resources, making synchronisations more reliable.

Optional display of public event titles

Event titles can now be made visible to users if desired, providing greater flexibility when displaying public events.

Special access points for bookings

Specific access points can now be added to bookings, each linked to individual access permissions.

Optimising bookings across multiple time zones

Booking time slots spanning several days have been improved for different time zones, ensuring that international scenarios are accurately reflected.

Extended rights for orders

Roles can now be specifically granted permission to view orders, allowing for more granular control over access rights.

Streamlined management of external participants

The rights management system for the approval process has been revised and made more clearly structured.

2025-12.1.1

Advanced rights management for ServiceUnits

Service units can now be set as mandatory for users.

Whether a ServiceUnit must be completed is determined by the mapping between ServiceUnits and roles and is therefore part of the permissions system.

A role may be granted the right to book a service, whilst at the same time being required to specify the relevant service unit.

2025-11.1.3

Improvements to the tile and map views

The image in the 'All' tile view can now be uploaded individually and customised at any time.

The tile view has been made more stable and reliable overall.

Improved booking processes and usability

A direct link has been added to the booking reminder email, which takes you straight to the relevant booking.

Bookings can now be created without being assigned to a user. The new permission ‘Create bookings without a user’ is available for this purpose. This allows non-administrators to create appointments without assigning a user; the user can be added at any time afterwards.

The ‘Generate code’ function is now called ‘Generate access PIN’. It is only displayed if a lock is present, is enabled by default, and cannot be changed if the necessary permissions are missing.

In addition, it is now possible to zoom in on maps.

2025-10.1.3

Booking on displays

The process of making a booking directly on the screen has been made noticeably more user-friendly.

2025-10.1.2

Check-in optimisation

Various improvements have been made to the check-in and check-out process.

2025-10.1.1

Check-in

The check-in function ensures that rooms and resources are only marked as occupied when the person or group who has booked them is actually present. A check-in therefore serves to validate bookings and prevents reserved rooms from remaining blocked without being used.

Check-in can be carried out in various ways, for example by scanning a QR code, via a button on a room display, or via the user interface on your own device. Whether and how check-in is required is controlled centrally via booking rules within the organisational units.

The configuration allows the check-in process to be flexibly adapted to different usage scenarios – from mandatory use for certain room types to anonymous confirmations by visitors via the display.

Recurring bookings

In addition to the existing method of creating batch entries, there is now a new way to create batch entries with a wider range of functions.

2025-08.3.1
