Find and install ember-cli latest LTS version using npm

The builds page of ember-cli lists

The latest LTS release is 2.4.5, made on April 11th, 2016

But when I try npm install -g ember-cli@2.4.5, I receive an error version not found: ember-cli@2.4.5.

Also, I was unable to find v2.4.5 on Github releases. The last 2.4.x version is 2.4.3.

Am I missing something?
