A word of warning ...
It’s really tempting to switch the post table version to 3.0, which then doesn’t store any glyph names in the font, saving file size especially for web fonts.
But for TrueType-based fonts (also packaged in WOFF, WOFF2), doing this will prevent the macOS autohinting from doing its job. Fuzzy contours and uneven stem weights are the result.
I was reminded of this after wondering why some fonts from a well-known monopolist didn’t look very good in the browser.
