int generators distribution no longer clustered around zero

In the post Understanding FsCheck, it was mentioned ints generated are not uniformly distributed but clustered around zero.

// see how the values are clustered around the center point
intGenerator
|> Gen.sample 30 10000
|> Seq.groupBy id
|> Seq.map (fun (k,v) -> (k,Seq.length v))
|> Seq.sortBy (fun (k,v) -> k)
|> Seq.toList

I believe it is no longer true since FsCheck 2.14.0 release. I verified that the results are now uniformly distributed by running the code snippet above.
