 **错误码**
 <br/>如果是无模式写入过程中的数据本身错误，应用会得到 TSDB_CODE_TSC_LINE_SYNTAX_ERROR 错误信息，该错误信息表明错误发生在写入文本中。其他的错误码与原系统一致，可以通过 `taos_errstr()` 获取具体的错误原因。
 
-**后续升级计划**
-<br/>当前版本只提供了 C 版本的 API，后续将提供 其他高级语言的 API，例如 Java/Go/Python/C# 等。此外，在TDengine v2.3及后续版本中，您还可以通过 taosAdapter 采用 REST 的方式直接写入无模式数据。
+<br/>除使用 C 版本的 API，也可以使用官网连接器，包括 Java/Go/Python/C#/Node.js/Rust 等。此外，在 TDengine v2.4 及后续版本中，您还可以通过 taosAdapter 采用 RESTful 的方式直接写入无模式数据。

 **Error code**
 <br/>If users do not write data following corresponding protocol syntax, application will get TSDB_CODE_TSC_LINE_SYNTAX_ERROR error code, which indicates error is happened in input text. Other generic error codes returned by TDengine can also be obtained through taos_errstr API to get detailed error messages.
 
-**Future enhancement**
-<br/> Currently TDengine only provides clang API support for Schemaless. In future versions, APIs/connectors of more languages will be supported, e.g., Java/Go/Python/C# etc. From TDengine v2.3 and later versions, users can also use taosAdaptor to writing data via Schemaless through RESTful interface.
+<br/> Beside TDengine C/C++ Schemaless API, you can use the API of other official connectors as well, including Java/Go/Python/C#/Node.js/Rust. From TDengine v2.4 and later versions, users can also use taosAdaptor to writing data via Schemaless through RESTful interface.
