The following settings shouldn't exist: rsync_only_changed

[djokodonev]

Hi, after installing the module and using the settings as per recommendation, i am seeing the following error:

# -*- mode: ruby -*-
# vi: set ft=ruby :

# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"

# Vagrant changed their default server url to 'https://vagrantcloud.com'
# Originally, it was using 'https://atlas.hashicorp.com'
# This helps fix the provisioning
#Vagrant::DEFAULT_SERVER_URL.replace('https://vagrantcloud.com')

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "centos/7"
  config.vm.hostname = "wwww.localsite.domain.com"
  config.vm.provision :shell, :path => "bootstrap.sh"
  config.vm.provision :shell, :path => "server/httpd.sh", :run => 'always'
  config.vm.network "private_network", ip: "192.168.50.001"
  config.vm.rsync_only_changed.rsync_on_startup = true
  config.vm.synced_folder ".", "/home/vagrant/sync", :nfs => true, :mount_options => ["rw","async"]
  config.ssh.insert_key = false
end

$ vagrant -v
Vagrant 2.1.1
