• Fixed problem with orthotropic materials when , is the decimal separator. • Updated the materials lists • Added warning message about mixing non-isotropic layers. • Changed algorithms so that the abrupt transition in mid frequencies when connecting materials of widely different critical frequency is removed or reduced. • For double masonry panels prevent timber or steel studs inducing panel modes. • Added an input field into Settings so that the user can enter the Company name (which can be lost after updates) • Fixed error when calculating TL of thin porous materials (TL at low frequencies was set to 0 dB which was not correct) • User lists (materials, profiles, glazing, floor covers and porous absorbers) include regional sensitivity and can now be filtered by region, similar to Insul lists • Updated list items counter • Minor updates to the Material's Editor interface and functions to improve usability
