- Add Bearer Token authentication, supporting tunnel access control via the --auth-bearer parameter - Refactor large modules into smaller, more focused components to improve code maintainability - Update dependency versions, including golang.org/x/crypto, golang.org/x/net, etc. - Add SilenceUsage and SilenceErrors configuration for all CLI commands - Modify connector configuration structure to support the new authentication method - Update recent change log in README with new feature descriptions BREAKING CHANGE: Authentication via Bearer Token is now supported, requiring the new --auth-bearer parameter
