We're excited to release ACARS 2.0, a major update built on a solid new foundation that brings significant improvements and sets the stage for future enhancements.

<Note>**Update Required**: Please update your Pegasus ACARS client as soon as possible to ensure continued compatibility and access to new features. [Download now](https://canadava.com/software)</Note>
<Warning>ACARS v1 will be sunsetted on **October 20, 2025, at approximately 17:00 UTC**.</Warning>

#### Key Improvements

* **Improved Layout**: Redesigned interface
* **Flap Detection**: Accurate flap value names for most aircraft (e.g., Flaps value of 2 will display as "Flaps 15")
* **Enhanced FSUIPC Stability**: Improved interface with FSUIPC for more stable and error-resistant connections
* **MSFS 2024 Support**: Full livery detection support for Microsoft Flight Simulator 2024
* **Landing Rate G-Force**: Now records and detects G-force on landing, sampled at 40Hz for precise measurements. We are going to update the points system soon to reflect this new feature.
* **Improved Landing Detection**: Better runway turnoff and taxi start detection after landing
* **Expanded Landing Summary**: More detailed landing summary messages
* **Cabin Sounds**: You can now customize cabin sounds within the ACARS client

#### ACARS v1 Sunset

* After this date, it will be impossible to log in to Pegasus v1
* **All in-progress flights** being done with Pegasus v1 will be lost
* Please ensure you update to Pegasus v2 before this date to avoid any disruption to your operations

#### Windows Users

* You must install the latest compatible version of [FSUIPC](https://www.fsuipc.com/) for your simulator (free version is sufficient)
* If you use X-Plane, no additional downloads are needed - Pegasus connects via UDP
* **Important**: Pegasus, FSUIPC, and your simulator should not be run in Admin mode unless absolutely necessary
* If admin mode is required, all three components must be run as Admin (Pegasus, FSUIPC, and the simulator)
* If Pegasus cannot detect your FSUIPC, ensure FSUIPC/Simulator is not running as admin

#### macOS / Linux Users

* You must install the latest version of [.NET Runtime 9](https://dotnet.microsoft.com/en-us/download/dotnet/9.0) before running Pegasus
* Failure to install .NET Runtime will result in Pegasus not launching
* **Linux Users**: You may need to `chmod +x` the downloaded AppImage to make it executable
