I was having some problems with Titanium Developer yesterday so I deleted the app and the support libraries (I'm using Snow Leopard) and reinstalled. Was offered the 1.1.0 mobile SDK and things were more or less okay.
Now I see in the upper right of Developer "New Titanium Developer available (version 1.0). Click to download"
By my math 1.1 is newer than 1.0, I'm assuming I should ignore this? LOL
Sorry, this is a issue with how our update services detect new release. It's currently not smart enough to know that you're on an unreleased version since the public version is still 1.0. Because of that, it's offering you the most recent "public" version which is still 1.0. You can safely ignore the message for now.
Titanium SDKs can exist on the same environment, so I suppose it was because that what you've downloaded was prior to 1.0. Thus it's looking for downloads for both 1.0 and 1.1.
True, but it looks like it's not the SDK it's trying to update but the Developer itself.
