Hi,
the last BJS commit https://github.com/BabylonJS/Babylon.js/commit/534f87a3f70c5264310185aa4d34db6801f06ae8
just erased my former feature in CreateCylinder() in VertexData.ts (feature hasRings) https://github.com/jbousquie/Babylon.js/commit/2b4f2feaa601c5ab5c51f6360c959472525c9a92
And I have no idea how to get this feature back as I can't re-PR my branch to the core.
