Windows specific: Selected mode button (Simple/Advanced/Expert) has now an orange background to make the active mode more distinct # 6860.This should lower the probability that PrusaSlicer will be reported as a potential threat. Windows specific: Several function calls that might have been considered suspicious by anti-virus software were replaced by alternatives.OSX specific: The PrusaSlicer and G-code viewer application icons were updated with the new rectangular background to match the new OSX icon style # 6874 thanks xarbit.This is a similar issue to the dreaded Nahimic OSD issue # 6864which we blacklisted in PrusaSlicer 2.4.0-alpha1. We added AMHook.dll to a blacklist so a warning dialog will be shown on startup when that DLLs is injected into PrusaSlicer # 2939. Windows specific: InnoCielo Meridian injects AMHook.dll into PrusaSlicer, which makes PrusaSlicer to crash.This also solves the Windows 10 dark mode issue, where we were not able to adjust status bar colors # 6860. Bottom status bar was removed and replaced by notifications showing progress of slicing and the 'abort slicing' button.This has been improved: The fixed / remaining errors are newly shown clearly at the side panel and the 'exclamation mark' icon is shown with white color for a completely fixed mesh, while an orange color is used for a not fully fixed mesh. Mesh repair statistics used to be confusing: It was not quite clear which errors were fixed during import and whether there are any errors remaining after the mesh import and repair.3MFs, AMFs and OBJs are loaded considerably faster, models imported from them are no longer repaired automatically (see 'Architecture and infrastructure' below for further details).While the new G-code conforms to standard, it may not be consumed by some non-conforming applications # 6996.

The G-Code coordinates are newly exported without emitting the leading and trailing zeros, which makes the G-code a bit smaller.This results in significant improvement of performance: The total slicing time is now 2x to 4x shorter, higher speed up is achieved on high-end CPUs # 2263. G-Code export was parallelized and optimized.Improvements with respect to PrusaSlicer 2.4.0-alpha1 To let you enjoy the alpha without worries, the alpha builds save their profiles into PrusaSlicer-alpha directory, so you may use the alpha side by side with the current release without ruining your production configuration. The most important change is significant speed-up of the G-Code generator. This alpha adds several new features and improvements and it fixes bugs found in the first alpha. This is the second alpha release of PrusaSlicer 2.4.0, following 2.4.0-alpha1.
