Core heap not available

Core heap not being available. I have installed Core and Core_kernel via opam.
“Core.Heap” is not available here.

open! Core

let pq = Heap.create ;;

Error :
24 | let pq = Heap.create ;;
Error: Unbound module Heap

Command to compile : “ocamlfind ocamlc -package core -linkpkg”

“opam install core” output is as follows:
[NOTE] Package core is already installed (current version is v0.13.0).

Is heap support removed from Core or am I missing something basic?

My understanding is that Heap is now Pairing_heap, located
in a sublibrary (namely core_kernel.pairing_heap).

For some reason, we missed this move while preparing the
changelog for v0.13; sorry for the inconvenience.

Thanks a ton. For future user following worked for me
“ocamlfind ocamlopt -linkpkg -package core_kernel.pairing_heap”

Is it possible to fix this documentation or raise a bug which fixes this?

I ran into the same issue:!topic/ocaml-core/nMscbnfAf5Y

This post was helpful to me in figuring that out. Thanks @Rahul_Sr .

I noticed that Pairing_heap is missing from the API docs as well:
