 This library class enables Dynamic Host Configuration Protocol (DHCP) functionality for the [Wiznet W5500 chip](http://wizwiki.net/wiki/lib/exe/fetch.php?media=products:w5500:w5500_ds_v106e_141230.pdf). It depends on the Wiznet W5500 library, so be sure to include the DHCP library after the W5500 library.
 
 **To include this library in your project, add the following at the top of your device code:**
 
 ```squirrel
 #require "W5500.device.lib.nut:2.2.0"
-#require "W5500.DHCP.device.lib.nut:2.0.0"
+#require "W5500.DHCP.device.lib.nut:2.0.1"
 ```
