This looks great thanks @Debakel - I'm just waiting for CI to pass before merging. And the team is hoping that we'll get a release out soon

@rowanwins hi! When is this going to be released?

[rowanwins]

Hi @antonmelbardis - this should now be available in 7.0.0-alpha.0 which is available on npm

[antonmelbardis]

@rowanwins thank you sir!

fyi- still getting Error: feature2 MultiPolygon geometry not supported on 7.0.0-alpha.0

[antonmelbardis]

@rowanwins @nick-romano yeah, the issue is still there unfortunately

@antonmelbardis @nick-romano The PR implemented booleanContains(feature1, feature2) only for cases where feature1 is a MultiPolygon and feature2 is a Polygon. Reversed operands are still not supported (but seems like there's already another PR for this: #2357).

➡️ It's only possible to check wether a Polygon is contained by a MultiPolygon and not vice-versa.
➡️ It's currently not possible to check wether a MultiPolygon contains a Point, Line or any other geometry type than Polygon.

I'm looking for point(MultiPolygon, Point), but maybe there's another way to accomplish that.

Found it! booleanPointInPolygon(). This function could be worth a mention from the booleanContains() docs.
