## [](#1-5-5)1.5.5

**October 18, 2021**

### What’s New

- When FTP Connector attempted to use the MLSD command to list the directory, the server responded with `Command Not Implemented (502)` and before the connector could retry the operation with a LIST command, the server closed the connection. A call to the FEAT command is now issued to validate that MLST/MLSD commands are supported by the server.
