FONTLOG for Odra Serif
=====================

This file provides detailed information on the Odra Serif font software.
This information should be distributed along with the Odra Serif fonts
and any derivative works.

Basic Font Information
----------------------
Odra Serif is a Modified Version of Source Serif 4
(https://github.com/adobe-fonts/source-serif), Copyright 2014–2023 Adobe,
designed by Frank Grießhammer, licensed under the SIL Open Font License 1.1.
'Source' is a Reserved Font Name and is not used in Odra Serif.

Odra Serif is intended as a serif companion to Odra Sans
(https://github.com/abhilashsahoo/odra-sans). Version 0.100 is an engineering
and metrics release: it applies a uniform vertical scale so the x-height
matches Odra Sans (520 UPM units), renames the family to Odra Serif, and
aligns typo/hhea vertical metrics with Odra Sans. It does not introduce
original letterform design; outlines remain those of Source Serif 4 after
that uniform Y-scale.

ChangeLog
---------
0.100 (2026-10-31)
- Initial public Modified Version under SIL OFL 1.1.
- Starting point: Source Serif 4.005 variable Roman TTF.
- Instantiated upright Text styles at opsz=20: ExtraLight (200), Light (300),
  Regular (400), SemiBold (600), Bold (700), Black (900).
- Renamed family / PostScript / related name IDs to Odra Serif / OdraSerif
  (Adobe Reserved Font Name 'Source' not used).
- Copyright: Adobe (original Source Serif 4 notice) + Copyright 2026
  Abhilash Sahoo (Infyways).
- Designer name ID: Abhilash Sahoo (based on Source Serif 4 by
  Frank Grießhammer / Adobe).
- License name IDs: OFL 1.1 summary; URL https://openfontlicense.org.
- Uniform Y-scale of glyph outlines so OS/2 sxHeight = 520 (Odra Sans
  x-height). Pre-scale Text Regular sxHeight was 475 (scale ≈ 1.0947);
  other weights scaled from their own pre-scale sxHeight to 520.
  - Set typo/hhea from Odra Sans (descender -250, lineGap 0); set
    typoAscender/hhea.ascent to 962 (above post-scale Agrave yMax 961;
    Odra Sans used 950). Shared usWinAscent/Descent 1106/359 across the
    family; USE_TYPO_METRICS on.
  - Unmapped a few archaic Greek small-letter codepoints that lack
    capitals in Source Serif 4 (glyphs retained, unencoded).
  - Flattened nested TrueType components; removed Mac name records;
    added smart-dropout prep instructions (Font Bakery).
- Version 0.100. Outputs: static TTF, OTF (CFF), and WOFF2 for each weight.
