PrusaSlicer 2.3.0-alpha3

Summary

This is the third alpha release of PrusaSlicer 2.3.0, following 2.3.0-alpha1 and 2.3.0-alpha2. This release mostly fixes bugs found in previous alphas, but it also adds several new features (such as Repetier server support) and 3rd party profiles.

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.

Improvements with respect to PrusaSlicer 2.3.0-alpha2

• The descriptions of configuration parameters in settings tabs now work as hyperlinks that open the respective page in our online help center. There is no hyperlink when the page does not exist for the parameter.
  
• Added support for Repetier server print host. (thanks @docbobo, #4384)
• New option in Preferences allows to invert mouse wheel for zooming (#1336, #4395, #4701)
• OSX specific: Settings dialog for 3DConnexion devices (Cmd+M) was enabled again to allow configuration of speed. The dialog was removed in 2.3.0-alpha1 in hopes that all related settings would be configurable in driver settings directly, but this turned out not to be the case for old 3DConnexion devices, which are not supported by the 3DConnexion driver correctly (#4892)
• G-Code Viewer is now able to extract config from gcode created by Slic3r and Slic3rPE (#4982)
• G-Code shows name of loaded .gcode in the title bar
• G-Code Viewer reports invalid .gcode files
• New icons for standalone G-Code Viewer
• Tool marker in G-Code preview is visible by default when the horizontal slider is not at its end position.
• Configuration snapshots were extended to capture and restore SLA print profiles, SLA material profiles and Physical printers configuration.
• Reworked Export finished notification. It now contains path to G-code, "Open folder" hyperlink and Eject removable media button.
• Renamed "FDM Support Editing" to "Paint-on supports" and "Seam Editing" to "Seam painting", new icon for the paint-on supports gizmo.
• Linux: Integration of Flatpak configuration files thanks to @xarbit (#3064, #4039)
• Linux: Added a desktop file for standalone G-Code Viewer
• Filament stats exported to G-code are now exported with higher precision to match values shown in the UI (#780, thanks to @stelgenhof)
• Unmount message slightly reworded by @vranisimo, thanks (#4523)

Bugs fixed, regressions with respect to PrusaSlicer 2.2.0

Bugs fixed, reported for PrusaSlicer 2.3.0-alpha2

• Fixed crash in monotonous infill happening in very specific geometry situations.
• Notifications were sometimes erroneously shifted to the left in Preview mode.
• Shift+Tab erroneously showed/hid the sidebar in the standalone G-Code Viewer (#5009)
• Parsing of the G-Code annotations was made more specific so that comments provided by the user through custom G-Codes will not be interpreted as PrusaSlicer's own annotations (#4992)
