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