 Added a new option to allow users to choose default tab when creating a new project or
opening an existing project
 Replaced the character space with underscore in the name field of certain output files
Bug Fixes:
 Fixed a bug that prevented sensitive receptor file from being generated for certain runs using
BREEZE-enhanced FORTRAN executables
 Fixed a bug that caused inconsistent display of vertical level heights for Cartesian gridded
receptors in the 3D window
 Fixed a bug that removed model object files after a run was completed
 Fixed a bug that prevented terrain surface or shaded relief files to be generated for certain
AERMAP runs
 Fixed a bug that caused crash when using Automated License Management to unlock the
software

Known Issues:
 When the multi-year option is enabled in the Control Options, subsequent years must be run
immediately after prior years in order to properly read the output files.
 Some USB Hardware Keys (dongles) for multi-core licenses of AERMOD that were issued for
use with the 11103 and earlier executables will not be compatible with the most recent
editions of the AERMOD Parallel and BREEZE AERMOD Parallel executables. These keys may
need to be updated; please contact Support with related questions.
 When using the click/drag tool to add rectangular objects in the Map Tab, in some cases the
orientation of the object will "flip" requiring the user to manually move it to the originally
intended position. It is recommended that users begin drawing all rectangular objects in the
bottom left corner of the object to avoid this orientation flip.
 Event runs must be executed immediately after the corresponding standard AERMOD run.
