 ### Probes
 
-Current firmware version: 2.9
+Current firmware version: 2.10 (aka. v30).
+
+> **NOTE**: The firmware version is not the same as the version shown by WCH's toolchain. Because WCH calculates the version number by `major * 10 + minor`, so the firmware version 2.10 is actually v30 `0x020a`.
 
 - WCH-Link [CH549] - the first version, reflash required when switching mode
 - WCH-LinkE [CH32V305][CH32V307]
