# _Vulkan Feature Development Checklist Template_

_This template captures checklists for the stages of development that
a Vulkan KHR extension passes through as it moves from development to
ratification and release. You should create an issue from this template
when the extension draft is stable and there is reasonable consensus in
the working group that it is on a path to ratification._

_Edit the template to suit the extension you are considering (and to
delete the italicized instructions). Delete any requirements that are not
relevant; for example, an extension that has no language dependencies
will not need SPIR-V / GLSL / HLSL items, and an EXT GLSL extension
will not require Promoter ratification._

_Requirements may be waived by vote of the working group, provided
that a 2/3 majority of non-abstaining vote are in favor._

## Preconditions for Call for Votes (CfV)

_A formal CfV is issued following agreement at a Tuesday meeting that a
vote should be held at the following Tuesday meeting. Preconditions
for a CfV are as follows; "specification stable" means that there are
no MRs in flight that modify behavior defined by the extension and its
dependencies. Delete any of the following preconditions that are not relevant to
the extension in question_
