This version makes the Inkscape extension compatible with Inkscape 1.0. It is no longer compatible with earlier versions (use older releases for that).
The output file can now be chosen using a file dialog instead of having to type a path, and a more helpful error message is given when trying to export an empty drawing.
The command-line binary for macOS has been rebuilt with clang and libc++ (as well as the latest versions of libpng and zlib) to fix an “Abort trap: 6” when called with nonexistent or invalid files. This also seems to have made it a bit faster. The binaries for Linux and Windows are unchanged.
