… in DePatchify. Previously, `DePatchify` always initialized its output projection with Flax's default initializers, preventing DiT models from customizing or zero-initializing the final output projection. Add `dense_kernel_init` (defaulting to `nn.linear.default_kernel_init`) and `dense_bias_init` (defaulting to `nn.initializers.zeros_init()`) attributes to `DePatchify` and pass them to the `Dense_Out` layer.
