Any update/upgrade for Text to Image SDXL?

hey, your text to image service is very good. i like it very much. my favorite is sdxl. with a not much words for prompt we can generate a good images.
do you have plan for update/upgrade sdxl? maybe new model hash version, adding sampler lika karras, adding controlnet? make it the results more like midjourney?
thx alot, master! (^.^)d
