The Go Fonts were originally released in 2016 and version 2.008 came out in 2017. It's taken longer that we'd have liked, but we have just released version 2.010 as of commit 41969df7:
- Fix the "knobbly l" in Go Medium and Go Medium Italic.
- Fix the unintentional swap of u-acute and u-circumflex in Go Smallcaps and Go Smallcaps Italic.
- Add U+01CD ..= U+01DC Pinyin diacritic-vowel combinations.
- Add U+2070 ..= U+208E superscript and subscript numerals. The existing superscript 1, 2, 3 and n were adjusted for consistency (e.g. superscript '1' now has a baseline if regular '1' does).
- Add U+037E GREEK QUESTION MARK.
- Add U+222A UNION.
- ttfautohint upgraded to the latest version, from 1.6 to 1.8.
Unlike the v2.008 changes, the v2.010 changes were largely [algorithmically generated (https://github.com/nigeltao/fontscripts/tree/master/cmd/upgrade-go-fonts-to-v2010). Algorithmic means that e.g. the new "a-caron" glyph is made by copy/pasting parts of the existing "a" and "s-caron" glyphs. Similarly, "superscript 4" is a scaled and translated "regular 4" and "union" is roughly an upside-down "intersection", after accounting for any italic 'lean'.
That program is mostly one-off textual grunt-work before and after the
ttx tool converts fonts between binary and textual formats. It's probably not very interesting, but I've linked it anyway for reproducibility.
How to get or use these fonts hasn't changed. If you just want the TTF files, run
and copy them from the subsequent
image/font/gofont/ttfs directory. Alternatively, they are also mirrored at https://github.com/golang/image/tree/master/font/gofont/ttfs
