Is Cardano fixed?

Could you please elaborate on the statement "Is Cardano fixed?"? I'm curious to understand what you mean by "fixed" in this context. Are you referring to a technical issue that has been resolved? Or perhaps, you're inquiring about the stability of the Cardano blockchain? Additionally, could you provide more background information or specify the aspect of Cardano you're particularly interested in discussing? It would help me to provide a more accurate and informative response. Thank you for clarifying your question.
