MatrixOne ODBC 9.7.0-mo.3 (Windows x64 preview)

MatrixOne ODBC 9.7.0-mo.3（Windows x64 开发预览版）

本版本基于 main@5cc5e1297f93809b1ea7352a1881b67c22b3a3ff 构建，
并在 MatrixOne main@484e1969531e7fbf7219b20e34d7ef23e110560b
上完成最终验证。

主要变化

• 加固直接 ODBC 的结果元数据、数值转换、Unicode 与兼容路径；
• 修复 Power BI 所需的 MatrixOne 元数据和 Connector 兼容路径；
• MSI 默认将 MatrixOne.mez 部署到 Power BI Desktop 的标准目录；
• 完善 MSI 的安装、修复、升级、降级拦截和卸载行为；
• 9.7.0-mo.1 可原位升级到 9.7.0-mo.3，系统 DSN 保留；
• 增加 Windows 包生命周期自动化及独立进程连接探测。

验证摘要

• Unicode/ANSI ODBC 连接最新 MatrixOne main：PASS；
• mo.1 → mo.3 原位升级：PASS；
• MSI 修复、降级拦截、卸载重装：PASS；
• 便携 ZIP 中文/空格路径、依赖缺失恢复、卸载：PASS；
• Microsoft Power Query SDK 公开测试：206/212，与既有基线一致，
  0 个新增回归；
• Windows、Linux、macOS 和源码检查 CI：PASS。

安装与升级

新安装可直接运行 matrixone-odbc-9.7.0-mo.3-winx64.msi。已安装
9.7.0-mo.1 的机器可直接运行新 MSI 完成升级。升级前请保存报表并完全
退出 Power BI Desktop；安装完成后重新启动 Power BI Desktop。

本版本尚未进行代码签名，因此继续标记为 Pre-release，面向开发、联调和
兼容性验证。详细结果见 TEST-REPORT-v9.7.0-mo.3.md。

MatrixOne ODBC 9.7.0-mo.1 (Windows x64 preview)

# MatrixOne ODBC 9.7.0-mo.1 (Windows x64 preview)

First developer preview of the self-contained MatrixOne ODBC driver and Power
BI connector for Windows x64, validated against MatrixOne main at
0f145bbc0a020e979e5bc2515de1a8a21ae4f222.

Highlights:

• Self-contained MSI and portable ZIP; no customer-side MySQL SDK or MySQL
  Server installation is required.
• Unicode and ANSI ODBC drivers, setup utility, required runtime libraries,
  authentication plugins, and MatrixOne.mez are bundled.
• Real Power BI Desktop Import and DirectQuery validation passed.
• DirectQuery grouping/aggregation returned the expected Unicode and decimal
  results (??=1234.50, total 1287.25).
• Power Query error handling now accepts both table- and list-shaped ODBC error
  details, and the connector uses opportunistic TLS for standard MatrixOne
  deployments.
• Unicode prepared-parameter and MatrixOne regression diagnostics were
  strengthened in the deep test suite.

Install the MSI as administrator, or extract the portable ZIP and run
Install.bat as administrator. For the unsigned preview connector, Power BI
Desktop must be configured to allow unvalidated custom extensions and then
restarted. See docs/POWER_BI.md in the ZIP.

Validation summary: both Unicode and ANSI smoke suites passed; both deep suites
reported 13 passes, 5 linked XFAILs, and 0 unknown failures. See the attached
test report for full versions, known MatrixOne issues, and remaining validation
scope.

This is an unsigned prerelease intended for development and compatibility
testing, not a production support declaration.

Power BI coverage note: this preview used a purpose-built five-row fixture. Multi-table public datasets, full query-folding coverage, scale/performance, Power BI Service, and on-premises gateway remain release gates. See the attached Chinese test report: TEST-REPORT-v9.7.0-mo.1.md.
