We are announcing the release of Habitat 1.6.513. This release is largely just a follow up to last week's core package refresh. All components included in the 1.6.513 Habitat release were built against the refreshed core packages and the 1.6.513 studio includes a full set of refreshed packages.

Please read on for the changelog details.  
Thanks for using Habitat!
