Lets you easily beta test plugins by notifying you of beta versions. Also lets you upgrade to beta versions from within WordPress.
This plugin aids with beta testing WordPress plugins hosted on wordpress.org. Once Plugin Beta Tester is activated, WordPress will notify you of new beta versions of plugins, not just new stable versions, and you'll be able to upgrade to these beta versions with just one click within WordPress.
Make sure to make frequent backups while you beta test plugins, and make sure to report bugs. Thanks for helping test plugins!
