+## MySQL 9.6.0 Upgrade Notes
+
+This module has been upgraded to support MySQL 9.6.0 (Innovation track), bringing:
+- **Enhanced Security**: Removed `mysql_native_password` authentication (deprecated in 8.4, removed in 9.0)
+- **Default Authentication**: Now uses `caching_sha2_password` with SHA-256 encryption
+- **Improved Performance**: Better query optimization and execution
+- **New Features**: Enhanced JSON support, EXPLAIN ANALYZE, and VECTOR data type support
+
+### Authentication Compatibility
+MySQL 9+ no longer supports `mysql_native_password`. The client library automatically uses `caching_sha2_password` by default. Server administrators must ensure user accounts use compatible authentication methods:
+```sql
+ALTER USER 'username'@'host' IDENTIFIED WITH caching_sha2_password BY 'password';
+```

+## Server Administrator Migration Guide
+
+When upgrading an MTA server to use MySQL 9.6+, server administrators need to ensure their MySQL server configuration is compatible:
+
+### Authentication Method Update
+MySQL 9.0+ has removed `mysql_native_password` authentication. All database users must use `caching_sha2_password`:
+
+```sql
+-- Check current authentication plugins
+SELECT user, host, plugin FROM mysql.user;
+
+-- Update users to use caching_sha2_password
+ALTER USER 'mtauser'@'%' IDENTIFIED WITH caching_sha2_password BY 'password';
+FLUSH PRIVILEGES;
+```
+
+### Connection Requirements
+- Ensure MySQL server is version 8.0+ (MySQL 9.x is backwards compatible with MySQL 8.x clients)
+- If using SSL/TLS, ensure OpenSSL 3.4.2+ is installed
+- The `get_server_public_key=1` option (enabled by default) allows secure password exchange
+
+### Compatibility Notes
+- MTA server with MySQL 9.6+ client library **can connect to** MySQL 8.x servers (using `caching_sha2_password`)
+- MTA server with MySQL 9.6+ client library **cannot connect to** MySQL servers using `mysql_native_password` only
+- For optimal security, upgrade both the MTA server's client library and the MySQL server to version 9.x

+# MySQL 9.6.0 Upgrade Notes
+
+## Overview
+This document describes the upgrade from MySQL 8.4.6 to MySQL 9.6.0 for the MTA:SA MySQL database module (`dbconmy`).
+
+## What Has Been Done
+
+### 1. Version References Updated
+- Updated `vendor/mysql/include/mysql_version.h` to MySQL 9.6.0 (version ID: 90600)
+- Updated `vendor/mysql/README.md` with MySQL 9.6.0 source references
+- Updated main `README.md` to indicate MySQL 9.6+ support
+
+### 2. Documentation Added
+- Added MySQL 9.6.0 upgrade notes to `vendor/mysql/README.md`
+- Added authentication compatibility information
+- Added server administrator migration guide
+- Added patch file compatibility notes
+
+### 3. Code Compatibility
+- Added comments in `CDatabaseConnectionMySql.cpp` explaining MySQL 9+ authentication
+- Verified that existing code uses `MYSQL_OPT_GET_SERVER_PUBLIC_KEY` which is compatible with MySQL 9's `caching_sha2_password`
+- No source code changes required - the existing implementation is forward-compatible
+
+## What Still Needs to Be Done
+
+### 1. Compile MySQL 9.6.0 Client Libraries (Windows)
+The actual MySQL 9.6.0 client library binaries need to be compiled following the instructions in `vendor/mysql/README.md`:
+
+**Required for:**
+- Windows x86 (`vendor/mysql/lib/x86/libmysql.lib`)
+- Windows x64 (`vendor/mysql/lib/x64/libmysql.lib`)
+- Windows ARM64 (`vendor/mysql/lib/arm64/libmysql.lib`)
+
+**Note:** The current libraries in `vendor/mysql/lib/` are still MySQL 8.4.6 binaries. These need to be replaced with MySQL 9.6.0 binaries compiled using the instructions provided.
+
+### 2. Update Patch File (If Needed)
+The `vendor/mysql/mysql-server.diff` patch was created for MySQL 8.4.6. When compiling MySQL 9.6.0:
+- Try applying the patch: `git apply vendor/mysql/mysql-server.diff`
+- If it fails, manually update the patch for MySQL 9.6.0 source code changes
+- Test that the patch applies cleanly and the build succeeds
+
+### 3. Linux Build Dependencies
+Currently, Ubuntu 24.04 Noble repositories only provide MySQL 8.0.x packages (`libmysqlclient-dev`):
+- The code will compile against MySQL 8.x headers with updated version info
+- For true MySQL 9.x support on Linux, wait for official Ubuntu packages or compile from source
+- The current setup is forward-compatible and will work with MySQL 9 once packages are available
+
+### 4. Testing
+After compiling MySQL 9.6.0 libraries:
+1. Build the MTA server with new libraries
+2. Test connection to MySQL 8.4+ server using `caching_sha2_password`
+3. Test connection to MySQL 9.x server
+4. Verify all database operations work correctly
+5. Test SSL/TLS connections
+
+## Breaking Changes in MySQL 9.0+
+
+### Authentication
+- **Removed**: `mysql_native_password` authentication plugin (completely removed in 9.0)
+- **Default**: `caching_sha2_password` using SHA-256 encryption
+- **Impact**: Server administrators must update user accounts to use compatible authentication
+
+### Server Migration Required
+```sql
+-- Check current authentication
+SELECT user, host, plugin FROM mysql.user;
+
+-- Update to caching_sha2_password
+ALTER USER 'mtauser'@'%' IDENTIFIED WITH caching_sha2_password BY 'password';
+FLUSH PRIVILEGES;
+```
+
+## Compatibility Matrix
+
+| MTA Server Library | MySQL Server | Compatible | Notes |
+|-------------------|--------------|------------|-------|
+| MySQL 9.6.0 | MySQL 9.x | ✅ Yes | Optimal configuration |
+| MySQL 9.6.0 | MySQL 8.4+ | ✅ Yes | Using `caching_sha2_password` |
+| MySQL 9.6.0 | MySQL 8.0+ | ✅ Yes | Using `caching_sha2_password` |
+| MySQL 9.6.0 | MySQL 5.x/8.x | ❌ No | If using `mysql_native_password` only |
+
+## Benefits of MySQL 9.6.0
+
+### Security Enhancements
+- Stronger authentication with SHA-256
+- Removal of weak `mysql_native_password` (SHA-1 based)
+- Enhanced SSL/TLS support
+
+### Performance Improvements
+- Better query optimization
+- Improved execution planning
+- Enhanced caching mechanisms
+
+### New Features
+- Enhanced JSON support and functions
+- EXPLAIN ANALYZE for query performance analysis
+- New VECTOR data type for AI/ML workloads
+- Improved stored procedures and triggers
+
