 # Heddle changelog

+### Added
+
+- Latin Extended-A (U+0100 to U+017F) and Ș ș Ț ț. Accented letters
+  are components; Đ đ Ħ ħ Ŧ ŧ Ł ł ĸ Ŋ ŋ ſ and the dotless j are drawn.
+  New marks: macron, breve, dot above, caron, double acute, ogonek,

+  398 glyphs, 338 code points.
+- Features `frac`, `numr` and `dnom`.
+- Kerning for lowercase pairs and for figures against punctuation.
+- Masters at wdth 85: 16 masters.
+- Hinting: the static TTF are hinted with ttfautohint 1.8.4
+  (ttfautohint-py 0.6.1, pinned).
+- `tools/readability.py`: an OCR check against 0.1 and DejaVu Sans.
+- Proofs: `heddle-latin-ext.png`, `heddle-symbols.png` and before/after
+  sheets for the marks, the counters and the drift.
+
+### Changed
+
+- Marks are lighter and smaller. Narrow bases (ı I l ȷ) get narrow
+  marks, so ï Ï Ĩ ĺ keep the advance of their base. Capital marks stay
+  below the typo ascender; win ascent is now 950 (was 1051).
+- Minimum counter rule: rings keep an open counter at Black (inner
+  radius at least 0.25 S, at most 38 units). The hooks of f, t, j (and
+  ſ ŋ Ŋ £) get wider at heavy weights so their counters stay open.
+- ß, ð, @, ©, ®, % redrawn with the counter rule (© ® with lighter
+  inner letters; ð's ascender starts inside the bowl).
+- Tabular figures at wdth 85 are 0.85 of their width (the sketch
+  value); 0.1 gave 0.9.
+- Overlap removal for the statics: union, snap to integers, split
+  self-touching contours, wind by nesting depth, check. The fallbacks
+  of 0.1 (jitter, unsimplified rounded paths) are gone.
+- The kerning test checks every member of every class.

+Heddle is a Swiss display grotesk built from four parts (rect, ring,

+- Kerning for lowercase pairs and for figures before a period.
+- Hinted static fonts (ttfautohint).

+## Better

+- Marks are lighter and smaller. ï and Ï no longer get wider at Black.
+- Small rings and the hooks of a, f, j, s and t stay open at Black.
+- ß, ð, @, ©, ® and % are redrawn.
