Hm, can't understand why it still have deprecations. Repo doesn't contain the code, shown in the warnings. And when I run tests locally, it passed successfully.
GeometricalPredicates v0.1.0 does not work under Julia 1.0, see here, and here. The master branch there does, but GeometricalPredicates requires a new version tag, probably v0.2.0. Then this PR would require v0.2.0 for Julia 1.0. After that, it might be that this package here requires some update.
GeometricalPredicates 0.0.5 doesn't support julia 1.0
