AttributeError: `Glyph` object has no attribute `isVarComposite`

[RickyDaMa]

Guessing an API has shifted under you, or maybe this type wasn't expected to end up here?

Diffenator2 invocation:

diffenator2 diff --fonts-before SomeUrduFont-old.ttf --fonts-after SomeUrduFont-new.ttf --out diffenator_report -s masters

Output:

Thanks Ricky! I saw the title and wondered if I was suffering from amnesia. Since I have an open pr, https://github.com/googlefonts/diffenator2/pull/147 I guess I am.

Fixed in a new release, https://github.com/googlefonts/diffenator2/releases/tag/v0.4.3
