Fixed wrapping of text in modal dialogs, unnecessary line breaks were sometimes present.Clicking 'Delete All' button to delete all currently defined G-Code substitutions is newly followed by a confirmation dialog, so it is not possible to delete the entries by mistake #7850.Because only Marlin firmware suffers from this issue in reality and there is an explicit check for the G92 E0 when Marlin is selected, we have now modified the G-Code Preview so the loss of precision problem is not visualized. Related to the previous improvement: our G-Code preview works by mimicking the Marlin firmware, therefore if the G92 E0 was missing and the error accumulation became visible, it would also be visible in the G-Code preview.From this version, the check is only applied for Marlin firmware, because as far as we know, other firmware flavors do not suffer from this issue.

This is needed to prevent error accumulation in firmware.

In 2.4.1-beta1, we added a check that G92 E0 is present in layer change G-Code when relative extruder addressing is used.

PrusaSlicer 2.4.1-beta3 will offer to copy configuration from any older release into the beta configuration folder on the first invocation. This release saves its configuration into a dedicated beta configuration folder to avoid breaking production profiles. This patch release adds several little improvements and fixes some bugs found in the 2.4.1-beta1. This is another beta version of PrusaSlicer 2.4.1, a third patch release of PrusaSlicer 2.4.0 (beta2 was not released publicly). The fix has been postponed into PrusaSlicer 2.5 release.

macOS specific: The fix of Cmd+M shortcut not minimizing the application which was made in beta3 was reverted, because it made PrusaSlicer crash on older macOS versions( #7981).

This could also have caused occasional crashes when sending file to print host ( #7681, #7173 and #7845)

Windows specific: When loading a 3MF by double clicking the file, the project name was sometimes (depending on current local codepage) mangled when the file name contained non-ASCII characters.

G-Code Substitutions were incorrectly applied on the commented-out configuration block at the end of the G-Code #7952 (this was fixed in beta3 already).G-Code Substitutions were incorrectly applied on initial and final M73 internal placeholders, which unexpectedly mangled the M73 commands #7978.If you already tested any of the PrusaSlicer 2.4.1 beta builds, you will be offered to import the recent beta profiles. The release candidate builds save their profiles to the same directory as the last release. For list of new features in the 2.4 series, please read the release logs of all 2.4.0/2.4.1 releases. This release only fixes several bugs found in beta3.

This is a release candidate of PrusaSlicer 2.4.1, following 2.4.1-beta1 and 2.4.1-beta3.
