What year did the CR come out?

Could you please clarify for me? I'm a bit confused about the acronym "CR". Could you be referring to a specific cryptocurrency, a financial regulation, or perhaps some other type of release? If it's a cryptocurrency, would you mind providing more context, such as the name of the project or its purpose? Additionally, if you're inquiring about a specific year of its launch, could you be more precise with your query? It would greatly assist me in providing an accurate answer. Thank you for your cooperation.
