Elasticsearch and Kibana 7 still on 7.11

[WolfangAukang]

Describe the bug

Recently, I have been trying to create a NixOS server with Elasticsearch and Kibana, both on version 7. Currently, Nixpkgs points that both (Elasticsearch and Kibana) on 21.11 are on version 7.16.1 (#150879 is the PR where this is updated), but when I check the versions on the server, they are still on version 7.11.1, as shown below:

[root@nixos-elk:~]# curl localhost:9200
{
  "name" : "testing-1",
  "cluster_name" : "testing",
  "cluster_uuid" : "k_Lq7jarRveNHgZVbxSM7w",
  "version" : {
    "number" : "7.11.1",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "ff17057114c2199c9c1bbecc727003a907c0db7a",
    "build_date" : "2021-02-15T13:44:09.394032Z",
    "build_snapshot" : false,
    "lucene_version" : "8.7.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

[root@nixos-elk:~]# kibana --version --allow-root
7.11.1

Steps To Reproduce

Steps to reproduce the behavior:

1. Create a configuration.nix file with the following setup:

{ modulesPath, lib, pkgs, ... }: {

  # AWS Defaults 
  imports = [ "${modulesPath}/virtualisation/amazon-image.nix" ];
  ec2.hvm = true;

  # Server
  networking.hostName = "nixos-elk";

  # Applications
  nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
      "elasticsearch"
      "kibana"
  ];
  services = {
    elasticsearch = {
      enable = true;
      package = pkgs.elasticsearch7;
      cluster_name = "testing";
      single_node = true;
      extraJavaOptions = [
        "-Xmx512m -Xms512m"
      ];
      extraConf = ''
        node.name: testing-1
        path.data: /data/elasticsearch
      '';
    };
    kibana = {
      enable = true;
      package = pkgs.kibana7;
      listenAddress = "0.0.0.0";
      extraConf = { 
        server.name = "testing";
      };
    };
    ssm-agent.enable = true;
  };
}

2. Run nixos-rebuild switch
3. Check if Elasticsearch and Kibana are on the stated version.

Expected behavior

Elasticsearch and Kibana on version 7.16.1

Have you upgraded your nixos channel recently? Try sudo nix-channel ---upgrade, then nixos-rebuild switch.

Yes, that helped in updating it. As the Elasticsearch update was from December, I thought the current AMI was able to pick these changes.
