luminance 0.46.1 needs unpublished luminance-derive

error[E0438]: const `ATTR_COUNT` is not a member of trait `luminance::vertex::Vertex`

    = note: this error originates in the derive macro `Vertex` (in Nightly builds, run with -Z macro-backtrace for more info)

This is with luminance v0.46.1 and luminance-derive v0.9.0. It looks like commit ef7417c was included in the latest luminance version but there's no matching luminance-derive commit.

Thank you. Done.
