+!!Incompatible Changes and Possible Transition Issues
+
+  - Poco::Net::NetworkInterface::findFirstAddress() (1.5.0) was renamed to firstAddress() (1.5.1).
+  - typedef Poco::Net::NetworkInterface::MacAddress (1.5.0) was renamed to MACAddress (1.5.1).
+  - introduced NetworkInterface::Type (1.5.1).
+  - unsigned Poco::Net::NetworkInterface::hwType() (1.5.0) changed to NetworkInterface::Type type() (1.5.1)
+  - Please note that 1.5.x releases are development releases and not considered stable. Interfaces may
+    change, and backwards compatibility with the stable 1.4 release series
+    is not guaranteed. There may also be some rough edges. 
+    The next stable release incorporating 1.5 features will be 1.6.
