We are pleased to announce the ninth patch to the 4.0 version of the Xibo CMS. The codename for this version is “Westphal”.

> 20D/Westphal 3 was a periodic comet with an orbital period of 61 years. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years). It was originally discovered by the German astronomer J. G. Westphal on July 24, 1852.

## Install / Upgrade

Instructions for installation/upgrade can be found [here](https://xibosignage.com/install-upgrade).

**Please note**: it is difficult to get PHP-ZMQ working on PHP8.1 under Windows/IIS; this [community post](https://community.xibo.org.uk/t/solved-v4-0-0-some-bugs-zmq-problems-zmq-for-php-8-2-10-nts-openssl-3-legacy-setting-to-windows-server-iis/29954/17) outlines a method for doing so.

### Players

We recommend using player software of the same version as your CMS. The latest player software is available [here](https://xibosignage.com/downloads).

Earlier versions of the player will connect to a v4 CMS in legacy mode.

**Please note:** Xibo for webOS and Xibo for Tizen players require v3 R308 and above to function with a v4 CMS. View the latest player software [here](https://xibosignage.com/downloads).

## Feedback

Xibo is built on feedback from our users, community and customers. Please let us know what you think of v4 in the comments.
