Is electrum a safe cryptocurrency wallet?

Could you elaborate on the safety measures implemented in Electrum, a cryptocurrency wallet, and assess its overall security? I'm considering using it to store my digital assets, but I'm concerned about potential vulnerabilities or risks. Specifically, I'd like to know if it offers secure encryption methods, regular updates to address security threats, and whether there have been any reported security breaches in the past. Additionally, I'm interested in understanding how it compares to other popular wallets in terms of safety. Your insights would greatly assist me in making an informed decision.
