Afterbyte Mono v3.0.0 — Four formats · 197 glyphs
Afterbyte Mono v3.0.0 — Four-format OFL package
Release milestone 3 of 3: an original continuous-vector technical monospace, supplied in OTF, TTF, WOFF, and WOFF2.
This is a regular GitHub release. Milestone numbering is separate from the underlying source/font build version 0.3.0-alpha, which is preserved inside the binaries and source snapshot. The existing validated font bytes are unchanged; publishing a regular release does not imply a new glyph design or completed cross-platform certification.
Glyphs and character coverage
197 glyphs total: 196 Unicode-mapped glyphs plus the .notdef fallback glyph. One Regular style; every glyph has a 650-unit advance.
| Character group | Count |
|---|---|
| Uppercase ASCII letters A–Z | 26 |
| Lowercase ASCII letters a–z | 26 |
| Digits 0–9 | 10 |
| ASCII punctuation and symbols | 32 |
| Space | 1 |
| Extended Latin letters | 56 |
| Nonbreaking space | 1 |
| Currency symbols | 4 |
| Extended punctuation and math | 12 |
| Arrows | 6 |
| Box drawing | 11 |
| Blocks and shading | 4 |
| Status and geometric symbols | 7 |
| Unicode characters | 196 |
All 95 printable ASCII characters are included, plus 101 additional Unicode characters. Coverage is selected, not the complete Latin-1 or Unicode blocks.

The ZIP includes coverage.txt with every supported Unicode code point. No new Unicode mappings were added over the 0.2 study; the existing 196-character repertoire was redesigned for 0.3.
What changed from v2.0.0
0 Unicode characters added or removed. This milestone adds the OTF and WOFF distribution formats and packages the OFL and repository updates. The glyph repertoire remains 196 mapped characters.
Changes included in the current design
- Continuous vector outlines replace the earlier pixel construction.
- Signature forms: flat-top A, dotted zero, single-storey a/g, rounded bowls, and redesigned R/Q, numerals, and terminals.
- Metrics: 1000 units per em, 700 cap height, 500 x-height, 650-unit fixed advances, and 820/−220 typographic ascender/descender. Layouts may reflow when upgrading from 0.2.
- Genuine OpenType/CFF OTF plus TTF, WOFF, and WOFF2 builds, CSS fallbacks, and checksums.
- SIL Open Font License 1.1 included and embedded in all four formats; no Reserved Font Names are declared.
- Retired display-family files removed; repository documentation, contribution templates, and checks now focus on Afterbyte Mono.
- GitHub Sponsors support configured for the maintainer.
Downloads and installation
Download AfterbyteMono-v3.0.0.zip for the complete font package, including all four formats, CSS, coverage, OFL, installation notes, and font checksums. Individual font files are also attached.
Install either OTF or TTF for desktop applications; they share the same family and style names. Use WOFF2 for websites, with WOFF as a fallback. Replace cached older font installations and restart your application after upgrading.
Use SHA256SUMS-v3.0.0 to verify the ZIP and all four standalone font files. The ZIP also contains a font-only checksum manifest. SOURCE-SHA256SUMS preserves the earlier snapshot manifest; its archive entry uses the original snapshot filename.
Validation and limitations
All four formats pass source/outline agreement, contour topology, fixed-spacing and naming checks, full embedded-license checks, cross-format equivalence, HarfBuzz shaping, and FreeType raster smoke checks at 12/16/24/32/48/96 px. The automated build also checks reproducibility and local documentation links.
Current scope: one Regular style, selected Latin and symbols, no variable axes, no bytecode hinting, and no complete cross-platform installation or language-coverage audit.
License and support
Font software, sources, build scripts, artwork, and documentation: SIL Open Font License 1.1. Dependencies retain their own licenses. Earlier distributions retain the permissions already granted with them.
