I doubt all that much has changed. I use the same pepsi can stoves I built 8 years ago. They work fine, are essentially free, and I find them ideal for bike touring.
Their biggest weakness for backpacking is still that the fuel is less energy dense than other choices, so if you must go longer distances between restock the weight of the fuel offsets the weight savings of the stove. For bike touring it is easy to find fuel in small quantities (12 oz Yellow Heet) so you never need to carry much and it is the lightest stove/fuel option.
