I see a lot of posts about the Yun not showing up under "Ports", but I don't have a Yun option under "Board" in the IDE. Shouldn't I? If this is a FAQ, please just point me to where I can learn more, so I don't pester people with a bunch of newbie questions.
Doh! You're right - I was using a 1.0 build. I had seen the "Beta" under the 1.5 build section under "Downloads", and had completely ignored it. Thanks!
