[Important Notes]

[Security Updates]
- Applied multiple security updates to further enhance system security.
[Enhancement]
Desktop & Login
- Enhanced email security by adding SSL certificate validation for SMTP servers in “Desktop > Personal Settings > Email Account”. Predefined providers now enforce validation automatically, while custom servers offer a configuration choice. If the certificate fails validation, the system blocks email delivery and displays an error message to prevent the use of untrusted certificates.
