 # 变更记录 - @go/db
 
-## [1.0.5] - 2026-05-05
+## [1.0.12] - 2026-05-17
+- **SQLite 极致优化 (超高并发支持)**:
+    - **读写分离与零锁读取**: 读操作 (`Query`) 实现零锁定，配合 WAL 模式彻底解决读写互斥问题；写操作由应用层 `sync.Mutex` 统一排队，规避 `database is locked` 错误。
+    - **临界区最小化**: 将 FTS 重写、参数 JSON 化 (`flatArgs`) 及日志记录移出锁保护区，极大缩短了写锁持有时间。
+    - **工业级默认配置**: 
+        - 自动启用 `WAL` 模式、`NORMAL` 同步、`MEMORY` 临时存储及 `busy_timeout(5000)`。
+        - 引入 **动态 Mmap**：根据系统内存自动设置 `mmap_size` (最大 30GB 或物理内存的 1/4)，使大数据量访问接近内存速度。
+        - 默认 `MaxOpenConns` 提升至 100，优化多线程只读性能。
+- **稳定性**:
+    - 为 `Stmt` (预处理语句) 增加写锁保护。
+    - 优化事务锁机制，支持事务内的锁自动追踪与释放。
+
+## [1.0.11] - 2026-05-13
+- **基础设施对齐**:
+    - 移除 `encoding/json` 原生依赖，全面切换至 `apigo.cc/go/cast.UnmarshalJSON` 以增强类型兼容性。
+    - 移除测试代码中对 `os.Remove` 的直接调用，统一切换至 `apigo.cc/go/file.Remove` 以支持隔离文件系统。
+- **稳定性增强**:
+    - 验证并更新了测试用例，确保在 Go 1.25.0 环境下的执行稳定性。
+    - 更新 `TEST.md` 性能基准，反映基础设施对齐后的最新指标。
+
+## [1.0.10] - 2026-05-10
+- **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`。
+    - 验证了 `redis.NewIDMaker` API 变更后的集成稳定性。
+    - 增强了 ID 生成器的集成测试，覆盖了 Redis 路径。
+
+## [1.0.9] - 2026-05-09
+- **基础设施对齐**: 
+    - 升级 `apigo.cc/go/log` 至 `v1.1.13`。
+    - 为 `DBInfoLog` 和 `DBErrorLog` 实现 `Reset()` 方法，以遵循 `log` 的强制 Reset 契约。
+    - 调整 `DBLog` 内的字段 `pos` 索引，从 `6` 开始紧凑排列，消除索引空洞。
+- **测试增强**: 
+    - 修复多个测试用例 (`TestSmartDelete`, `TestGenericQuery`, `TestTableProbing`, `TestVersionControl`) 中因使用 `sqlite://:memory:` DSN 导致的初始化失败问题。
+    - 引入 `test_util.go` 和 `ResetAllForTest()`，确保测试间的全局状态隔离。
+
+## [1.0.6] - 2026-05-05
+### 优化
+- **日志体系重构**: 
+  - 引入 `DBInfoLog` 和 `DBErrorLog` 类型化日志，分别继承 `log.InfoLog` 和 `log.ErrorLog`。
+  - 利用 `log` 包的新特性实现“零手动”调用栈捕获，业务端仅需关注错误信息和 SQL 现场。
+  - 进一步解耦业务字段与日志元数据。
 ### 优化
 - **日志自主化**: 
   - 将数据库日志逻辑从 `log` 包迁移至 `db` 包，实现日志格式与业务逻辑的深度绑定。
