When was Electra discontinued?

Could you please provide some context on the cryptocurrency Electra and its discontinuation? I'm curious to know when exactly Electra ceased to exist or when its development and support were officially halted. Was there a specific announcement or event that led to its discontinuation? If so, can you elaborate on the reasons behind this decision? Additionally, how has the cryptocurrency market reacted to Electra's discontinuation, and what impact has it had on investors and the broader ecosystem?
