Release 3.3.1
First official release – provides the same set of features as UVPackmaster 3 for Blender.
Release 3.3.2
General improvements:
- New variant of the pack operation: Repack With Others. Repack all selected islands with all unselected islands which are already placed in the target box:

New utility operator: Measure Area (Merged): measure merged area of selected UV islands (area of overlapping UVs will be added to the result only once):

- Bug fixing.
Release 3.3.3
General improvements:
- Support for a new packing paradigm Fixed Scale (Max Margin): packing with a fixed scale while searching for the maximum margin between islands:

The new mode can be selected using a new option Scale Mode (which replaces the old Fixed Scale option). It can be set to one of 3 values:
- Max Scale (default):
equivalent to Fixed Scale set to off in older versions - Fixed Scale:
equivalent to Fixed Scale set to on in older versions - Fixed Scale (Max Margin):
the new mode as presented above.
- Max Scale (default):
- Ability to set the Scale Mode setting on a per-group basis in the Groups To Tiles mode using the overrides panel for a group.
Improvements for how the packing result is applied to the UV map when packing groups: starting from this version, the packer doesn’t wait for applying a result for a group until all groups are packed: instead it applies the result for a group immediately.
Fix for the Apply Grouping To Scheme operation.
- UI fixes and improvements.
Release 3.3.4
General improvements:
New option Arrange Non-Packed Islands: when packing with fixed scale, arrange the islands that cannot be packed due to a lack of space in a line above the target UV area. The arrangement will be done after the operation is complete:

Performance optimizations for assigning per-island parameters.
Performance optimizations for the Measure Area (Merged) operation.
Fix rare instabilities for the Orient UVs To 3D Space operation.
Bug fixes.
