smart-mcp-proxy/mcpproxy-go v0.16.8 on GitHub

This release focuses on stability improvements and bug fixes for OAuth token management and connection handling.

Bug Fixes

OAuth token cleanup: Fixed memory leaks by properly cleaning up orphaned OAuth tokens when MCP servers are removed from configuration. Tokens are now also cleaned up automatically on application startup to remove any stale credentials from previous sessions.
Version reporting: Corrected the build configuration to properly inject version information into the application binary, ensuring the correct version is displayed in logs and the UI.
Connection stability: Resolved issues with stale client state that could cause problems when reconnecting to upstream MCP servers. The core client state is now properly cleared before attempting reconnection, preventing connection failures and ensuring clean re-establishment of server connections.
