+# Version 0.26.0 (2021-10-2)
+
- **Breaking** The `draw` and `draw_indexed` commands on `AutoCommandBufferBuilder` now take parameters to explicitly specify the range of vertices and instances to draw.
- **Breaking** `BufferlessDefinition` is removed.
- **Breaking** The `VertexSource` trait is removed, and has been replaced with the new `VertexBuffersCollection` trait, which works analogously to `DescriptorSetsCollection`. Vertex buffers can now be passed in as a tuple, just like descriptor sets.
