Flex SDK 4.13 & Air 15.0 - 'Invalid namespace' issue

Hi,

Eventually I'm ending up with migrating from Flex SDK 4.10 (Air 3.8)
Flexmojos 6.0.1 to Flex SDK 4.13 Air 15 Flexmojos 7.0.1

I downloaded the Flex SDK 4.13 in couple with Air 15 (against default 14)
due to requirements of iOS deployment.

I successully compiled my projects, but now if I change the namespace of my
air app in descriptor file

from /<application xmlns="http://ns.adobe.com/air/application/3.8">/
to /<application xmlns="http://ns.adobe.com/air/application/15.0">/

I get the error
/...LauncherMobile-app.xml: error 102: Invalid namespace
http://ns.adobe.com/air/application/15.0/

Where I missed?
