Thank you @florianpreusner but looks like packagist need an update as well to pick up latest 5.4 version

[florianpreusner]

Fixed! Strange that I had to this manually. Thanks for the hint, @PWalkow! https://packagist.org/packages/eightpoints/guzzle-bundle

Because of some issues I removed v5.4 and released a new major version 6.0.
