WordPress is a very popular open-source blog software and is used widely throughout the Internet. However, with great success comes great attack potential: like any other wide spread open-source software, WordPress is target for frequent hacking attacks and spam-bots. All the more important is it to always update the distribution to the latest release.
As Debian/Ubuntu user, I am spoiled when it comes to update management: apt-get updates most of my software, and apticron notifies me when updates are available. For WordPress however, the packaged versions of Debian/Ubuntu are really old and less adjustable which unfortunately makes a manual installation inevitable. While there are several automated WordPress update mechanisms out there, I couldn’t find a simple notify-on-update tool.
This post introduces the WordPress Update Notifier (WP-UN), a simple script that frequently compares the installed WordPress version with the latest available one. If a new version is available, it sends an e-mail to a given address.
