   The latest version of the GRAL dispersion model, 24.04, has been released and it includes several updates and bug fixes. GRAL, a Lagrangian dispersion model, is extensively used for simulating pollutant dispersion, and these updates are expected to enhance its reliability in various environmental scenarios.

   A significant fix in version 24.04 addresses an issue that caused incorrect concentration calculations within buildings. This bug, present since version 23.11, affected flat terrain and certain building configurations. Correcting this issue ensures that GRAL can provide more accurate simulations in urban settings where building interactions play an important role.

   Since this month November 2022, GRAL dispersion model presents a new website: https://gral.tugraz.at/ The Graz Lagrangian Model - GRAL - was initially developed in 1999 at the Institute of Thermodynamics and Sustainable Propulsion Systems at Graz University of Technology.

   In addition, new features and bugfixes have been implemented in the new GRAL Version 22.09, which is now available on the GRAL homepage.

   The team developing the high-resolution model system GRAMM/GRAL, inside the Institute of Thermodynamics and Sustainable Propulsion Systems at Graz University of Technology, has just released the new version 23.11.

   GRAL 23.11 has been compiled for .NET 8!
- The GRAL release is no longer published as an all-in-one file by default. This means that the user must install the .NET8 Runtime!
- For Windows users, a published version as a single-file is still available in a separate download!
