 ## Current Master
 
+- Add better error messages for when a transaction fails on approval
 - Allow sending to ENS names in send form on Ropsten.
+- Added an address book functionality that remembers the last 15 unique addresses sent to.
+- Can now change network to custom RPC URL from lock screen.
+- Removed support for old, lightwallet based vault. Users who have not opened app in over a month will need to recover with their seed phrase. This will allow Firefox support sooner.
+- Fixed bug where spinner wouldn't disappear on incorrect password submission on seed word reveal.
+- Polish the private key UI.
+- Add Kovan as an option on our network list.
 
 ## 3.4.0 2017-3-8
