Release notes for FontLab 8.4.2.8942¶

18 September 2024

Optical Separation: Optical separation now correctly splits centerline vector images (open paths).

Import Metrics:: You can now correctly import metrics data from JSON files, you can now import metrics for multiple masters simultaneously, and you can import metrics expressions from JSON files.
Copy Metrics to Masters: Copy Metrics to Masters now copies all metrics values, not just expressions.
Kerning Interpolation: If a master is an intermediate master on one axis but an edge master on another axis, FontLab now correctly interpolates values for kerning pairs that are not defined in the master. This works with Match Kerning and during export. Previously, undefined kerning pairs were assumed to be 0 in this case.
Match Kerning Classes: Match Kerning now prioritizes kerning classes from the default master. If no kerning classes are found in the default master, it will use kerning classes from one of the corner masters. This addresses situations where kerning data is defined in the corners of the design space and needs to be interpolated for the default master.

Font Info Overview: In the Font Info dialog, the Overview page, you can now compare values and highlight differences between masters.
Default Font Dimensions Color: You can now specify the default color for font dimensions in Preferences > Guides and Grid.

If you use the repeater glyph in Glyph window, Echo Text now correctly works in the Preview panel.
You can no longer change the color of font dimension lines in the property bar.
