 ### Databases and data tools
 
-- Built-in support for MySQL, PostgreSQL, SQLite, DuckDB, SQL Server, Oracle, and ClickHouse; TDengine is provided as an installable extension driver, alongside Dameng DM, KingbaseES, GBase 8s, OceanBase, openGauss, Apache IoTDB, and Oscar.
+- Built-in support for MySQL, PostgreSQL, SQLite, DuckDB, SQL Server, and Oracle; ClickHouse and TDengine are provided as installable extension drivers, alongside Dameng DM, KingbaseES, GBase 8s, OceanBase, openGauss, Apache IoTDB, and Oscar.
 - Browse database objects, edit and run SQL with execution plans, import and export data, compare schemas and data, and visualize relationships with ER diagrams.
 - Dedicated Redis and MongoDB interfaces; middleware connections such as MQTT are provided through installable extensions (MQTT 3.1.1 over rustls, SSH tunneling, auto-resubscribe), with subscribe, messages, and publish views.
 - Table-data tabs support batch-editing selected cells, typed editors for date/time/numeric columns, and copying table or column names from context menus.

 - 浏览数据库对象，编辑和执行 SQL 并查看执行计划，导入导出数据，比较 Schema/Data，并通过 ER 图查看关系。
 - 专用的 Redis 与 MongoDB 界面；MQTT 等中间件连接改为通过扩展市场安装的扩展提供（MQTT 3.1.1 + rustls 加密，支持 SSH 隧道与断线自动重订阅），提供订阅、消息、发布三个视图。
 - 表数据页签支持批量编辑选中单元格，日期/时间/数值列使用对应的类型化编辑控件，支持右键复制表名与字段名。
