2 (This release includes features initially planned for version 2.0)
4 * Electrum servers were upgraded to version 0.9. The new server stores
5 a Patrica tree of all UTXOs, an idea proposed by Alan Reiner in the
6 bitcointalk forum. This property allows the client to directly
7 request the balance of any address. The new commands are:
8 1. getaddressbalance <address>
9 2. getaddressunspent <address>
10 3. getutxoaddress <txid> <pos>
12 * Command-line commands that require a connection to the network spawn
13 a daemon, that remains connected and handles subsequent
14 commands. The daemon terminates itself if it remains unused for more
15 than one minute. The purpose of this is to make scripting more
16 efficient. For example, a bash script using many electrum commands
17 will open only one connection.
20 * Fix for offline signing
22 * GUI usability improvements
23 * Coinbase Buyback plugin
26 * During wallet creation, do not write seed to disk until it is encrypted.
27 * Confirmation dialog if the transaction fee is higher than 1mBTC.
32 * Coin control: select addresses to send from
33 * Put addresses that have been used in a minimized section (Qt GUI)
34 * Allow non ascii chars in passwords
38 bugfixes: offline transactions
41 bugfixes: connection problems, transactions staying unverified
47 * fix regression with --offline mode
48 * fix regression with --portable mode: use a dedicated directory
52 * The client connects to multiple servers in order to retrieve block headers and find the longest chain
53 * SSL certificate validation (to prevent MITM)
54 * Deterministic signatures (RFC 6979)
55 * Menu to create/restore/open wallets
56 * Create transactions with multiple outputs from CSV (comma separated values)
58 * Plugins are no longer tied to the qt GUI, they can reach all GUIs
59 * Proxy bugs have been fixed
64 * Notification option when receiving new tranactions
65 * Confirm dialogue before sending large amounts
66 * Alternative datafile location for non-windows systems
67 * Fix offline wallet creation
68 * Remove enforced tx fee
69 * Tray icon improvements
75 * Menubar in classic gui
76 * Updated the QR Code plugin to enable offline/online wallets to transmit unsigned/signed transactions via QR code.
77 * Fixed bug where never-confirmed transactions prevented further spending
82 * Increase default fee
83 * fix create and restore in command line
84 * fix verify message in the gui
89 * Classic GUI can display amounts in mBTC
90 * Account selector in the classic GUI
91 * Changed the way the portable flag uses without supplying a -w argument
92 * Classic GUI asks users to enter their seed on wallet creation
97 * Transactions that are in the same block are displayed in chronological order in the history.
98 * The client computes transaction priority and rejects zero-fee transactions that need a fee.
99 * The default fee was lowered to 200 uBTC per kb.
100 * Due to an internal format change, your history may be pruned when
101 you open your wallet for the first time after upgrading to 1.7.2. If
102 this is the case, please visit a full server to restore your full
103 history. You will only need to do that once.
106 # Release 1.7.1: bugfixes.
111 * The Classic GUI can be extended with plugins. Developers who want to
112 add new features or third-party services to Electrum are invited to
113 write plugins. Some previously existing and non-essential features of
114 Electrum (point-of-sale mode, qrcode scanner) were removed from the
115 core and are now available as plugins.
117 * The wallet waits for 2 confirmations before creating new
118 addresses. This makes recovery from seed more robust. Note that it
119 might create unwanted gaps if you use Electrum 1.7 together with older
120 versions of Electrum.
122 * An interactive Python console replaces the 'Wall' tab. The provided
123 python environment gives users access to the wallet and gui. Most
124 electrum commands are available as python function in the
125 console. Custom scripts an be loaded with a "run(filename)"
126 command. Tab-completions are available.
128 * The location of the Electrum folder in Windows changed from
129 LOCALAPPDATA to APPDATA. Discussion on this topic can be found here:
130 https://bitcointalk.org/index.php?topic=144575.0
132 * Private keys can be exported from within the classic GUI:
133 For a single address, use the address menu (right-click).
134 To export the keys of your entire wallet, use the settings dialog (import/export tab).
136 * It is possible to create, sign and redeem multisig transaction using the
137 command line interface. This is made possible by the following new commands:
138 dumpprivkey, listunspent, createmultisig, createrawtransaction, decoderawtransaction, signrawtransaction
139 The syntax of these commands is similar to their bitcoind counterpart.
140 For an example, see Gavin's tutorial: https://gist.github.com/gavinandresen/3966071
142 * Offline wallets now work in a way similar to Armory:
143 1. user creates an unsigned transaction using the online (watching-only) wallet.
144 2. unsigned transaction is copied to the offline computer, and signed by the offline wallet.
145 3. signed transaction is copied to the online computer, broadcasted by the online client.
146 4. All these steps can be done via the command line interface or the classic GUI.
148 * Many command line commands have been renamed in order to make the syntax consistent with bitcoind.
153 * Added new version notification
155 # Release 1.6.1 (11-01-2013)
158 * It is now possible to restore a wallet from MPK (this will create a watching-only wallet)
159 * A switch button allows to easily switch between Lite and Classic GUI.
162 * Seed and MPK help dialogs were rewritten
163 * Point of Sale: requested amounts can be expressed in other currencies and are converted to bitcoin.
166 * The receiving button was removed in favor of a menu item to keep it consistent with the history toggle.
