# Changelog All notable changes to the SecureGuard package will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] ### Added - Hardcoded database connection for maximum security - Enhanced vendor-controlled security settings - Improved tamper resistance against client modifications ### Changed - Database connection is now hardcoded and cannot be overridden by clients - All security settings are vendor-controlled and fetched remotely - Client configuration reduced to minimal required parameters (licenseKey + schemas) ### Deprecated - vendorEndpoint parameter (now hardcoded for security) - Client-configurable security options (now vendor-controlled) ### Removed - Client ability to specify database connection - Client ability to override security settings - Optional security configurations ### Fixed - Critical vulnerability where clients could bypass protection by removing package - Security flaw where clients could specify their own database connection - Potential tampering through client-controlled security settings ### Security - **CRITICAL**: Database connection is now hardcoded and encrypted - **CRITICAL**: All security settings are vendor-controlled and cannot be modified by clients - **ENHANCED**: Improved tamper detection and integrity verification - **ENHANCED**: Stronger protection against package removal bypass attempts ## [1.0.0] -
