 Armitage Changelog
 ==================
 
+2 Mar 12 - Catching up to a few MSF 4.3.0-dev changes...
+--------
+- Added a tab rename feature.
+- Hosts that self report as .NET server now display an XP/2003 era icon.
+- Updated route command parser to conform to Metasploit 4.3.0's output for it
+- "Check all credentials" feature now works when running the deconfliction 
+  server AND client from the same folder.
+- [host] -> Host -> Operating System -> * now clears notes related to host
+  before updating OS. This allows future scans to trigger MSF normalization
+  code and update the OS to something else (e.g., from Unknown to X)
