v1.2.1
Breaking Changes
@mchudleigh has brought to my attention that loading procs without an existing instance breaks Vulkan spec. To address this issue a new vkPreload proc has been added and must be called before creating an Instance. After the creation of the Instance you can then load the remaining procs via vkInit which takes as a parameter the existing Instance.
To help with this little transition two new tags have been created, 1.2.0 and 1.2.1, although this doesn't conform with semver I hope it helps you select the right version.
