Fontbakery Technical Report

If you think a check is flawed or have an idea for a check, please file an issue at https://github.com/fonttools/fontbakery/issues and remember to include a pointer to the repo and branch you're checking.

DEPRECATION WARNING

By late-December 2024, FontBakery version 0.13.0 introduced a new naming scheme for the check-IDs.

Fontbakery detected usage of old IDs and performed an automatic backwards-compatibility translation for you.
This automatic translation will be deprecated in the next major release.

Please start using the new check-IDs as documented at /Lib/fontbakery/legacy_checkids.py

The following legacy check-IDs were detected:
- com.google.fonts/check/outline_colinear_vectors
- com.google.fonts/check/outline_short_segments
- com.google.fonts/check/ttx_roundtrip
- com.google.fonts/check/version_bump
- com.google.fonts/check/outline_semi_vertical
- com.google.fonts/check/outline_jaggy_segments
- com.google.fonts/check/fontdata_namecheck
- com.google.fonts/check/outline_alignment_miss
