0.4.1

This release adds no new features; it is purely to overcome a problem with a transitive dependency on binaryornot that prevents basic Briefcase usage of templates.

Bugfixes

• Briefcase now imposes a version pin on binaryornot < 0.5.0. Recent binaryornot releases introduced a series of bugs that cause catastrophic errors in PNG detection and file encoding. (#2712)

Misc

• #2726, #2727, #2729, #2730
