For the first time I got an email from my Wordpress installation yesterday, asking me to update. Have not seen that before. A nice detail I appreciate, so I don't have to keep up with what i the latest release of Wordpress at all times.

Interesting, AFAIK it's not something in the core. Which security plugin are you using?

[runarb]

I am not running any security plugins. I just had a look on the email headers, and it was sent from my server, so this must have come from Wordpress somehow. It is also the first one I have gotten.

The email seed:

Subject: [{my website} Wordpress MU] WordPress 4.2.2 is available. Please update!

Please update your site at http://{my websites url}.com to WordPress 4.2.2.

Updating is easy and only takes a few moments: http://{my websites url}.com/wp-admin/network/update-core.php

If you experience any issues or need support, the volunteers in the WordPress.org support forums may be able to help. https://wordpress.org/support/

Keeping your site updated is important for security. It also makes the internet a safer place for you and your readers.

The WordPress Team

I have the following plugins installed: All In One SEO Pack, FeedWordPress, Github Ribbon, Hello Dolly, Revision Control, Unfiltered MU, WordPress Importer and WP-Polls.

Maybe it originated from one of them?

I got this email too. I'm pretty sure I didn't seek out and install any plugins. I don't remember getting any of those you've listed. I nuked the install completely so I can't say for sure.
