3.6.2 polyfill breaking change from 3.5.0

[Pessimistress]

We previously used the following to generate all hexes at zoom 0:

h3
  .polyfill([[-90, -180], [90, -180], [90, 0], [-90, 0]], 0)
  .concat(h3.polyfill([[-90, 180], [90, 180], [90, 0], [-90, 0]], 0))

When upgrading to 3.6.2 from 3.5.0, the above code returns an empty array.

We have a dedicated function for this: h3.getRes0Indexes()

Can you use this instead? I agree that the behavior here should probably be considered a regression, but h3.getRes0Indexes() will be more reliable and considerably faster in any case.

I'm seeing breaking changes with this function as well. At resolution 2 I'm getting empty results. For instance:
h3.polyfill([[162, 72],[153, 72],[153, 81],[162, 81]], 2);
[]

We investigated in the core library and we're working on a fix. In the meantime, 3.6.3 rolls back to a slow-but-correct version of polyfill that should fix the issue until we have a faster version available.
