Wonderful work. We've built something similar inside our BusinessPress plugin (also manages updates, exposes hidden preferences & reduces WordPress branding). It would be great to join forces in fighting evil admin plugin notifications. Keep up the great work making WordPress the publisher-friendly CMS it deserves to be.

Great work, Thorsten

Every time I see Dobby instead of clutter, I briefly smile inside. 
House elves are great.

Thank you, Dobby!

Thank you very much for making this free for everyone :) 

Excellent work

This plugin removes the WordPress update nag that appears at the top of all admin pages when a new version of WordPress is released.
Tired of WordPress nagging you about a new release? Maybe you already know about it and want to hold off on an update and would rather not see the update nag on every admin page you visit. Activate this plugin and be bothered no more!
The status of your version of WordPress (be it current or out-of-date) is still reflected in the footer of your admin pages and in the update count link in the admin bar.
And certainly, of course, I don’t advocate completely ignoring the fact that updates often contain fixes for critical bugs or exploits. However, there are various other means of learning about updates; and once known, not everyone is able or willing to update immediately.
