3 * The client connects to multiple servers in order to retrieve block headers and find the longest chain

5 * Implements BIP32 (hierarchical deterministic wallet)
6 * Deterministic signatures (RFC 6979)
7 * Can create multiple accounts in the same wallet
8 * Menu to create/restore/open wallets
9 * Create transactions with multiple outputs from CSV (comma separated values)

45 * Classic GUI asks users to enter their seed on wallet creation
50 * Transactions that are in the same block are displayed in chronological order in the history.
51 * The client computes transaction priority and rejects zero-fee transactions that need a fee.
52 * The default fee was lowered to 200 uBTC per kb.
53 * Due to an internal format change, your history may be pruned when
54 you open your wallet for the first time after upgrading to 1.7.2. If
55 this is the case, please visit a full server to restore your full
56 history. You will only need to do that once.
59 # Release 1.7.1: bugfixes.
64 * The Classic GUI can be extended with plugins. Developers who want to
65 add new features or third-party services to Electrum are invited to
66 write plugins. Some previously existing and non-essential features of
67 Electrum (point-of-sale mode, qrcode scanner) were removed from the
68 core and are now available as plugins.
70 * The wallet waits for 2 confirmations before creating new
71 addresses. This makes recovery from seed more robust. Note that it
72 might create unwanted gaps if you use Electrum 1.7 together with older
75 * An interactive Python console replaces the 'Wall' tab. The provided
76 python environment gives users access to the wallet and gui. Most
77 electrum commands are available as python function in the
78 console. Custom scripts an be loaded with a "run(filename)"
79 command. Tab-completions are available.
81 * The location of the Electrum folder in Windows changed from
82 LOCALAPPDATA to APPDATA. Discussion on this topic can be found here:
83 https://bitcointalk.org/index.php?topic=144575.0
85 * Private keys can be exported from within the classic GUI:
86 For a single address, use the address menu (right-click).
87 To export the keys of your entire wallet, use the settings dialog (import/export tab).
89 * It is possible to create, sign and redeem multisig transaction using the
90 command line interface. This is made possible by the following new commands:
91 dumpprivkey, listunspent, createmultisig, createrawtransaction, decoderawtransaction, signrawtransaction
92 The syntax of these commands is similar to their bitcoind counterpart.
93 For an example, see Gavin's tutorial: https://gist.github.com/gavinandresen/3966071
95 * Offline wallets now work in a way similar to Armory:
96 1. user creates an unsigned transaction using the online (watching-only) wallet.
97 2. unsigned transaction is copied to the offline computer, and signed by the offline wallet.
98 3. signed transaction is copied to the online computer, broadcasted by the online client.
99 4. All these steps can be done via the command line interface or the classic GUI.
101 * Many command line commands have been renamed in order to make the syntax consistent with bitcoind.
106 * Added new version notification
108 # Release 1.6.1 (11-01-2013)
111 * It is now possible to restore a wallet from MPK (this will create a watching-only wallet)
112 * A switch button allows to easily switch between Lite and Classic GUI.
115 * Seed and MPK help dialogs were rewritten
116 * Point of Sale: requested amounts can be expressed in other currencies and are converted to bitcoin.
119 * The receiving button was removed in favor of a menu item to keep it consistent with the history toggle.
