Using the beta tester plugin, I follow trunk through every phase of development via five devices (iPhone 5, iPhone 6+, Nexus 5, iPad Air, Macbook). With the plugin installed, select “Bleeding edge nightlies”. Every day, your site will auto update to the latest nightly build. We committed long ago to ensuring that trunk is continuously dogfoodable and quickly fixed in the rare event that something nasty happens, like a fatal error. I have never once experienced loss of content while following trunk. If you follow this blog, consider putting the beta tester plugin on a real site that you use regularly. We must take this small extra risk with our own sites so that we truly see what we’re making before releasing it.
We desperately need mobile beta testers. WordPress will be a champion of the open mobile web. We will work around the iOS Safari bugs that hamper us. We will make the mobile web a better place. With the beta tester plugin installed on a public site, testing betas from any touch device is as straightforward as testing from the desktop. Despite this ease, 4.2 in its current state is a regression from 4.1 on mobile, particularly on iOS. We’ll work through these problems before release, but we really need mobile beta testers as well as mobile patch testers. Mobile patch testing (and patch testing in general) is not so easy to set up. We need better tools and documentation here.
Check out the Beta Testing section of the Core Development Handbook for help setting up the Beta Tester plugin. I’m always hanging out in the #core-flow Slack channel as @boren if you have questions. Let’s build a mobile beta audience.
