Automatic upgrades on live sites are, we think most people would agree, a Bad Idea. You can’t test them before they go live; they’ll play havoc with your version control system, if you’re using one; and if they fail or screw up, your live site is broken. Bad. Idea.
Enter Staunch. Staunch makes you stick to best practice for upgrades, by preventing even admins and superadmins from running WordPress’s automatic upgrade processes on your live site.
When you want to upgrade WordPress, you can do so on a local or development install of your site; after you’ve tested it and made sure everything’s okay, you can then deploy the site as you usually would — through version control, FTP, or something else.

Staunch

A WordPress plugin to prevent automatic updates on your live sites.

Have you ever needed to upgrade a plugin to it’s latest (unreleased) version? 
With SVN Updater you get a new action (Trunk) on the Plugins page.
Development of this plugin is done <a href="https://github.com/szepeviktor/svn-updater" rel="nofollow ugc">on GitHub</a>. 
Pull requests are welcome.

SVN Updater

Works well for such a simple plugin.
WordPress is lacking in a good way to phase users in to major plugin updates. (either you manually install from trunk, or get a surprise as soon as the stable tag changes)
I'd love to see this worked into a more fully fledged "beta tester" plugin that hooks into auto-updates when the dev version is bumped.



Just what I needed

Install any WordPress.org plugin's trunk version from SVN.
