 # 变更记录 - @go/db

+## [1.3.1] - 2026-05-13
+- **功能增强**:
+    - 全面支持“复杂标识符”：改进了 `LIKE` 拦截逻辑中的正则表达式，支持带引号（`` ` ``, `"`, `'`, `[]`）和特殊字符（如 `-`）的表名与字段名。
+    - 优化 `cleanIdentifier`：能够更精准地剥离多段式标识符（如 `table.column`）中的包装引号。
+    - 增强 `getFTSMatchSQLParts` 和 `extractTableName`：确保在各种引用风格下均能正确定位影子列和源表。
+- **基础设施对齐**:
+    - 升级 `apigo.cc/go/log` 至 `v1.3.2`。
+- **测试增强**:
+    - 新增 `TestComplexIdentifierFTS` 验证复杂标识符下的全文检索重定向。
+    - 修复并增强 `TestAutonomousFTS` 以支持多种引用风格的兼容性测试。
+
+## [1.3.0] - 2026-05-12
+- **基础设施对齐**: 
+    - 官方发布 v1.3.0 对齐版本。
+
+## [1.0.11] - 2026-05-11
+- **基础设施对齐**: 
+    - 最终基础设施对齐。
+
 ## [1.0.10] - 2026-05-10
 - **基础设施对齐**: 
    - 升级 `apigo.cc/go/redis` 至 `v1.0.8`。
