Release Notes
***************************

Version 4.1.0 (Current)
-----------------------

**Release date:** March 2024

**Highlights**

#. Upgrade the earthquake event generation toolbox to support simulation of Peak Ground Velocity (PGV) and liquefaction induced Permanent Ground Deformation (PGD).
#. Enhancements to the BRAILS-Buildings widget, providing detailed user interaction with the existing BRAILS building inventory generation capabilities. In brief, these enhancements enable:
   
   #. Importing footprint and building data from i) OpenStreetMaps, ii) Microsoft Global Building Footprints dataset, iii) FEMA USA Structures, and iv) user-specified data sources.
   #. Using National Structures Inventory data or other user-specified data to create a baseline building inventory.
   #. Requesting a subset of BRAILS attributes for inventory generation.

#. Update the damage and loss engine Pelicun to v3.3. 

Version 4.0.1
