h2o warning message too old cluster

Hi i'm using h2o in R.

Just a couple of weeks ago i update h2o package to the latest version

 h2o.getVersion()
[1] "3.20.0.2"

But when i Initialize a new h2o session with h2o.init i recieve a warning message like that

In h2o.clusterInfo() : 
Your H2O cluster version is too old (3 months and 9 days)!
Please download and install the latest version from http://h2o.ai/download/

What should I do? When I installed h2o for the first time I don't recall having any file downloaded from h2o website.

First remove any previously installed H2O packages for R.

if ("package:h2o" %in% search()) { detach("package:h2o", unload=TRUE) }
if ("h2o" %in% rownames(installed.packages())) { remove.packages("h2o") }

And then, download packages that H2O depends on.

 pkgs <- c("RCurl","jsonlite")
for (pkg in pkgs) {
  if (! (pkg %in% rownames(installed.packages()))) { install.packages(pkg) }
}

Download and install the H2O package for R.

install.packages("h2o", type="source", repos=(c("http://h2o-release.s3.amazonaws.com/h2o/latest_stable_R")))

Optionally initialize H2O and run a demo to see H2O at work.

library(h2o)
localH2O = h2o.init()
demo(h2o.kmeans)

Or you can simply check the following link:

http://docs.h2o.ai/h2o/latest-stable/h2o-docs/downloading.html#install-in-r

This is just an warning message, so if you want, you can continue to use the H2O version you are using.

Please note it is expected that you would get this warning message. H2O wants you to know whether or not you are using an up-to-date version.

If you want the message to go away, all you need to do is update to the latest stable release: http://h2o-release.s3.amazonaws.com/h2o/latest_stable.html
