X-Plane developer Toliss has published a new update for the A321, bringing the version number up to  V1.3.1. The update introduces some major new additions to the system simulations, which were derived from their A340 product alongside numerous small features and several bug fixes that polish the user experience.

The update is described by the developer as a significant port of the systems from the new A340 to the A321. In the updated version, the A321 simulated cargo heating, fuel temperature, and IDG temperature. Exterior lighting has also been redone along with the modified electrical system for more realistic operations. The full list of modifications can be found here.

Apart from the new features, the latest version also brings an array of bug fixes and quality of life improvements that range from refined call-outs to reworked IRS drift values. The full changelog can be found here. Currently, V1.3.1/build number 1463 can be installed via Xupdater or by redownloading the entire aircraft from different web stores, including X-Plane.org or, recently, the iniBuilds store.
