Unwrella v1.04 is both maintenance and feature release.
Fixes in this version:
* Licensing now working smoothly for the users with some of the non-english Windows regional settings
* New "Quads" unwrapping mode, in which UV chart borders are always on the quad boundaries. This increases compatibility with Editable Poly and exporting to .obj and other quad based formats.
This feature is still marked as "beta" because, for some models, it can produce a small number of overlapping UV faces. This can be checked for and fixed manualy using the built-in "Unwrap UVW" modifier.
