[TOC]
The latest version of OS Calendar has been reworked so that it can run as a complete booking solution on its own. This page summarises the main changes for existing and new customers.
| Area | What changed |
|---|---|
| Standalone use | OS Property is no longer required. OS Calendar has its own Properties management and a front-end Booking Search. |
| OS Property integration | Now optional. Choose Linked mode to synchronise properties with OS Property. |
| Room Types | Rooms are now managed as room types with quantity, occupancy, photos and amenities. |
| Room Units | Optional physical rooms (for example 101, 102) per room type, with status and blocking. |
| Rate Plans | Several rate plans per room type, with included services and stay / advance-booking limits. |
| Price Rules | Base, season, weekend, holiday and manual rules with priorities, replacing the old season price list. |
| Inventory | Daily availability by quantity, with stop-sell, block / unblock and overbooking options. |
| Promotions | Promo codes with percentage, fixed amount or free-night discounts and usage limits. |
| Cancellation Policies | Free, flat, tiered and non-refundable policies with a global default. |
| Front end | New Booking Search, My Bookings, Booking Lookup and Booking Detail pages. |
| Back-end menu | Reorganised into Booking, Properties, Pricing, Extra Fields and Settings. |
Needs verification: How prices and availability created with older versions (seasons and the date-based availability calendar) are carried over to rate plans, price rules and inventory should be confirmed with the product team. Always test a booking after upgrading.
