 ## [Unreleased]
 
+## [0.3.34] - 2026-10-06
+
+迁移 `0089`。部署后需重建 postgres 容器才启用语句统计：`docker compose --env-file .env.deploy up -d postgres`。
+
+### 调整（数据库）
+- 标题 / 别名模糊匹配改用 `%` 运算符，能走 trigram 索引（资源标题搜索在 8 千行上从 75 ms 降到 0.6 ms）；巡检结果回填加部分索引；删除无用的 `content_unit_air_date_idx`；`random_page_cost` 调为 1.1。
+- 数据保留补齐：引擎运行（终态、未被保留中的任务引用，缺省 14 天）、已投递事件、识别尝试（每条资源留最近 3 次）、已识别条目、站点快照；新增每天 04:40 的流水数据清理，分批删除并在删后 `ANALYZE`；保留天数在「设置 → 系统 → 数据保留」；`scripts/db-retention.ts` 可 dry-run / apply。
+- 启用 `pg_stat_statements`：运行状态页「存储」显示最慢 / 调用最多的语句与各表死元组。
+
 ## [0.3.33] - 2026-10-06
 
 迁移 `0086`、`0088`。
