Brooklyn Problem - PlatformJS not available as Public Resource for Force.com Sites

This issue has been resolved in Skuid Brooklyn - Iteration 1.1, which is now available on the Skuid Releases page

As a reminder, Salesforce does not allow reverting back to prior versions of managed packages. Skuid always recommends installing new versions in a non-business critical sandbox environment to test all mission critical functionality before installing into a production environment. Thank you.
