v6.8.0
- Rewrote composite glyphs' anchor propagation logic to better match the built-in Glyphs.app feature. This is based on the Rust implementation in fontc, in turn based on the original Objective-C code which was shared with us privately. It fixes various issues with anchor propagation (#368, #1011). Note that currently only 'master' layers have their anchors propagated (not unlike the old code which this replaces, see #1017).
