Caution, these are different things. The old 10 kWp "limit" referred to the proportionally payable Renewable Energy Act surcharge for self-consumption. This was increased to 30 kWp.
However, the hobby option seems to still apply to 10 kWp. The Bundesrat only made a proposal to the government in November '21 to also raise this to 30 kWp. However, I could not find any indication that this has already been codified into law. It is probably all just starting slowly under the traffic light coalition.
