- Updated minimum fonttools requirement to 3.9.2; fixes an issue in `fontTools.varLib.merger` with recombining multiple PairPosFormat2 subtables (https://github.com/fonttools/fonttools/issues/888)
- Added standalone `fontmake` executable bundling all the dependencies as well as the Python interpreter in a single file, pre-compiled for macOS and Windows (experimental). Simply unzip and run, no setup needed.
EDIT: On Windows, you may need to install Microsoft's `vc_redist.x64.exe`, which installs the run-time components required to run C/C++ applications built using Visual Studio 2015. Download it from the Microsoft website: https://www.microsoft.com/en-gb/download/details.aspx?id=48145
