A new v4 beta (version Dec-11-2017) is now available for download here: http://moi3d.com/beta.htm , also linked to from the download page on the main web site.

Bug fixes and changes:

Mac full screen mode - getting sent back to the desktop the first time you moved the mouse over each viewport after going to full screen mode should be finally fixed! Also Ctrl+Cmd+F shortcut key for full screen toggle should now work.

Mac trackpad and Magic Mouse - Finished implementing multitouch view navigation for the trackpad and Magic Mouse on Mac. Magic Mouse should be back to zooming instead of panning. The Zoom speed can be adjusted in moi.ini [MultiTouch] MagicMouseZoomSpeed=1.0 . Change this to something like 2.0 to make the default behavior faster or 0.5 to go slower. You can also hold down the Ctrl key to go slower as well.

Mac ignored mouse bug - Fix for bug where mousemove events would stop working in certain conditions when restoring the main window from hidden or showing a modal dialog. Fixes bug reported by Finema here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8675.189

Updated "On" object snap mechanics - Changed the way On object snap for curves works to get better accuracy with curves far from the origin.

Incorrect default values for some commands - Fixed a bug where the default values for the Text and Rebuild commands were incorrect on locales that use commas for the decimal separator. Reported by Vladimir on the forum here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8704.32

Trim - fixed a bug in the Edit > Trim command where if an object was set to be both an object to be trimmed as well as a cutting object it could get hidden unexpectedly.

Command button highlighting - Fix for command buttons remaining highlighted after command ends. Reported by Vladimir on the forum here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8704.32

Read-only file handling - Fix bug where using File > Save wasn't prompting for a new file name when the current opened file was set to read-only. Reported in the forum by mhasse here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8714.1

Crash fix for newer CPU/Older OS combination - Fix for 0xc000001d illegal instruction exception when running on Win7 SP0 with a newer AVX-capable CPU.

Hidden-line generation - Increase Canvas megapixel size limit from 175 to 1000.

Degenerate box error - fixed bug where a script error would be displayed if you made a degenerate rectangle in any of the Draw solid > Box commands.

Update text input fields - Text input fields were only applying typed in values when the input panel was open, or when the Enter or Tab keys were pressed, not if just clicking outside the field as they now will. Should fix a PDF export dialog bug reported by reported by Moujiik here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8704.15


Scripting:

viewport.setCameraAndTarget() - Fixed bug in viewport.setCameraAndTarget() function, reported in the forum by Ralf here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8704.25

Process memory use limit - Added option in moi.ini for limiting maximum memory use - Windows only. Can be set in moi.ini under [Settings] MaxProcessMemoryUse=x . Requested by Burr on the forum here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8704.26

moi.view.screenshot - Fix bug where the moi.view.screenshot() method was capturing the wrong area of the screen on Mac.


Enable setting default values for controls from shortcut keys. UI controls can now be triggered or initialized with custom values if the control's id is supplied in the command-line parameters for the command. For buttons, the presence of the button's id value in command line parameters will trigger a UI event for the button the first time that it is shown, this will have the same effect as clicking the button.
For dropdowns and checkboxes, the presence of the control's id in an id=value pair will use that value to initialize the control rather than taking the last used or default value as normal.

This makes it possible to set up shortcut keys that package up different options within commands, for example:

Trim addtrimpoints removekeepmode=keep

Trim addtrimpoints removekeepmode=remove

Trim isocurve isodir=u

Trim isocurve isodir=v

Line bothsides=true

Extrude tapered

EDIT: This was originally the Dec-11 version, rolled out a new Dec-12 release to fix a crash on Mac from one of the changes.
