+Bitcoin Improvement Proposals implemented
+-----------------------------------------
+BIP 22 - 'getblocktemplate', 'submitblock' RPCs
+BIP 34 - block version 2, height in coinbase
+BIP 35 - 'mempool' message, extended 'getdata' message behavior
+
+
 Core bitcoin handling and blockchain database
 ---------------------------------------------
 * Reduced CPU usage, by eliminating some redundant hash calculations
 * Cache signature verifications, to eliminate redundant signature checks
+* Transactions with zero-value outputs are considered non-standard
 * Mining: when creating new blocks, sort 'paid' area by fee-per-kb
 * Database: better validation of on-disk stored data
 * Database: minor optimizations and reliability improvements
 * -loadblock=FILE will import an external block file
+* Additional DoS prevention measures
 
 
 JSON-RPC API
@@ -30,31 +39,52 @@
 * Added raw transaction API.  See https://gist.github.com/2839617
 * Added 'getrawmempool', to list contents of TX memory pool
 * Added 'getpeerinfo', to list data about each connected network peer
+* Added 'listaddressgroupings' for better coin control
 * Rework gettransaction, getblock calls. 'gettransaction' responds for
   non-wallet TXs now.
 * Remove deprecated RPC 'getblocknumber'
+* Remove superceded RPC 'getmemorypool' (see BIP 22, above)
+* New blockchain checkpoint at block 193,000
+* listtransactions output now displays "smart" times for transactions,
+  and 'blocktime' and 'timereceived' fields were added
 
 
 P2P networking
 --------------
 * IPv6 support
-* Tor/I2P hidden service support
+* Tor hidden service support
 * Attempts to fix "stuck blockchain download" problems
 * Replace BDB database "addr.dat" with internally-managed "peers.dat"
   file containing peer address data.
 * Lower default send buffer from 10MB to 1MB
 * proxy: SOCKS5 by default
-* Support connecting by hostnames passed to proxy (-proxydns)
-* Add -seednode connections, and use this for -dnsseed + -proxydns
+* Support connecting by hostnames passed to proxy
+* Add -seednode connections, and use this instead of DNS seeds when proxied
 * Added -externalip and -discover
-* Add -onlynet to prevent connections to a given network
+* Add -onlynet to connect only to a given network (IPv4, IPv6, or Tor)
 * Separate listening sockets, -bind=<addr>
 
 
 Qt GUI
----------------------
-?????
-
+------
+* Add UI RPC console / debug window
+* Re-Enable URI handling on Windows, add safety checks and tray-notifications
+* Harmonize the use of ellipsis ("...") to be used in menus, but not on buttons
+* Add 2 labels to the overviewpage that display Wallet and Transaction status (obsolete or current)
+* Extend the optionsdialog (e.g. language selection) and re-work it to a tabbed UI
+* Merge sign/verify message into a single window with tabbed UI
+* Ensure a changed bitcoin unit immediately updates all GUI elements that use units
+* Update QR Code dialog
+* Improve error reporting at startup
+* Fine-grained UI updates for a much smoother UI during block downloads
+* Remove autocorrection of 0/i in addresses in UI
+* Reorganize tray icon menu into more logical order
+* Persistently poll for balance change when number of blocks changed
+* Much better translations
+* Override progress bar design on platforms with segmented progress bars to assist with readability
+* Added 'immature balance' display on the overview page
+* (Windows only): enable ASLR and DEP for bitcoin-qt.exe
+* (Windows only): add meta-data to bitcoin-qt.exe (e.g. description)
 
 Internal codebase
