3 * Electrum servers were upgraded to version 0.9. The new server stores
4 a Patrica tree of all UTXOs, an idea proposed by Alan Reiner in the
5 bitcointalk forum. This property allows the client to directly
6 request the balance of any address. The new commands are:
7 1. getaddressbalance <address>
8 2. getaddressunspent <address>
9 3. getutxoaddress <txid> <pos>
11 * In addition, two commands for message encryption were added:
12 1. encrypt <pubkey> <message>
13 2. decrypt <pubkey> <message>
15 The encryption algorithm is ECIES, and code was was borrowed from
16 https://github.com/jackjack-jj/jeeq. In order to know the public
17 key corresponding to a Bitcoin address in your wallet, you can use
18 the 'getpubkeys' command. The 'decrypt' command assumes that the
19 wallet has the private key corresponding to the public key passed as
22 * The encrypt and decrypt functions are available in the Qt GUI (from
23 the menubar, or right click on one of your addresses if you want to
26 * Command-line commands that require a connection to the network spawn
27 a daemon, that remains connected and handles subsequent
28 commands. The daemon terminates if it remains unused for more than
34 * Fix for offline signing
36 * GUI usability improvements
37 * Coinbase Buyback plugin
40 * During wallet creation, do not write seed to disk until it is encrypted.
41 * Confirmation dialog if the transaction fee is higher than 1mBTC.
46 * Coin control: select addresses to send from
47 * Put addresses that have been used in a minimized section (Qt GUI)
48 * Allow non ascii chars in passwords
52 bugfixes: offline transactions
55 bugfixes: connection problems, transactions staying unverified
61 * fix regression with --offline mode
62 * fix regression with --portable mode: use a dedicated directory
66 * The client connects to multiple servers in order to retrieve block headers and find the longest chain
67 * SSL certificate validation (to prevent MITM)
68 * Deterministic signatures (RFC 6979)
69 * Menu to create/restore/open wallets
70 * Create transactions with multiple outputs from CSV (comma separated values)
72 * Plugins are no longer tied to the qt GUI, they can reach all GUIs
73 * Proxy bugs have been fixed
78 * Notification option when receiving new tranactions
79 * Confirm dialogue before sending large amounts
80 * Alternative datafile location for non-windows systems
81 * Fix offline wallet creation
82 * Remove enforced tx fee
83 * Tray icon improvements
89 * Menubar in classic gui
90 * Updated the QR Code plugin to enable offline/online wallets to transmit unsigned/signed transactions via QR code.
91 * Fixed bug where never-confirmed transactions prevented further spending
96 * Increase default fee
97 * fix create and restore in command line
98 * fix verify message in the gui
103 * Classic GUI can display amounts in mBTC
104 * Account selector in the classic GUI
105 * Changed the way the portable flag uses without supplying a -w argument
106 * Classic GUI asks users to enter their seed on wallet creation
111 * Transactions that are in the same block are displayed in chronological order in the history.
112 * The client computes transaction priority and rejects zero-fee transactions that need a fee.
113 * The default fee was lowered to 200 uBTC per kb.
114 * Due to an internal format change, your history may be pruned when
115 you open your wallet for the first time after upgrading to 1.7.2. If
116 this is the case, please visit a full server to restore your full
117 history. You will only need to do that once.
120 # Release 1.7.1: bugfixes.
125 * The Classic GUI can be extended with plugins. Developers who want to
126 add new features or third-party services to Electrum are invited to
127 write plugins. Some previously existing and non-essential features of
128 Electrum (point-of-sale mode, qrcode scanner) were removed from the
129 core and are now available as plugins.
131 * The wallet waits for 2 confirmations before creating new
132 addresses. This makes recovery from seed more robust. Note that it
133 might create unwanted gaps if you use Electrum 1.7 together with older
134 versions of Electrum.
136 * An interactive Python console replaces the 'Wall' tab. The provided
137 python environment gives users access to the wallet and gui. Most
138 electrum commands are available as python function in the
139 console. Custom scripts an be loaded with a "run(filename)"
140 command. Tab-completions are available.
142 * The location of the Electrum folder in Windows changed from
143 LOCALAPPDATA to APPDATA. Discussion on this topic can be found here:
144 https://bitcointalk.org/index.php?topic=144575.0
146 * Private keys can be exported from within the classic GUI:
147 For a single address, use the address menu (right-click).
148 To export the keys of your entire wallet, use the settings dialog (import/export tab).
150 * It is possible to create, sign and redeem multisig transaction using the
151 command line interface. This is made possible by the following new commands:
152 dumpprivkey, listunspent, createmultisig, createrawtransaction, decoderawtransaction, signrawtransaction
153 The syntax of these commands is similar to their bitcoind counterpart.
154 For an example, see Gavin's tutorial: https://gist.github.com/gavinandresen/3966071
156 * Offline wallets now work in a way similar to Armory:
157 1. user creates an unsigned transaction using the online (watching-only) wallet.
158 2. unsigned transaction is copied to the offline computer, and signed by the offline wallet.
159 3. signed transaction is copied to the online computer, broadcasted by the online client.
160 4. All these steps can be done via the command line interface or the classic GUI.
162 * Many command line commands have been renamed in order to make the syntax consistent with bitcoind.
167 * Added new version notification
169 # Release 1.6.1 (11-01-2013)
172 * It is now possible to restore a wallet from MPK (this will create a watching-only wallet)
173 * A switch button allows to easily switch between Lite and Classic GUI.
176 * Seed and MPK help dialogs were rewritten
177 * Point of Sale: requested amounts can be expressed in other currencies and are converted to bitcoin.
180 * The receiving button was removed in favor of a menu item to keep it consistent with the history toggle.
