# Release 2.3
 * Improved logic for the network layer.
 * More efficient coin selection. Spend oldest coins first, and
   minimize the number of transaction inputs.
 * Plugins are loaded independently of the GUI. As a result, Openalias,
   TrustedCoin and Trezor wallets can be used with the command
   line. Example: 'electrum payto <openalias> <amount>'
 * The command line has been refactored:
  - Arguments are parsed with argparse.
  - The inline help includes a description of options.
  - Some commands have been renamed. Notably, 'mktx' and 'payto' have
    been merged into a single command, with a --broadcast option.
   Type 'electrum --help' for a complete overview.
 * The command line accepts the '!' syntax to send the maximum
   amount available. It can be combined with the '--from' option.
   Example: 'payto <destination> ! --from <from_address>'
 * The command line also accepts a '?' shortcut for private keys
   arguments, that triggers a prompt.
 * Payment requests can be managed with the command line, using the
   following commands: 'addrequest', 'rmrequest', 'listrequests'.
   Payment requests can be signed with a SSL certificate, and published
   as bip70 files in a public web directory. To see the relevant
   configuration variables, type 'electrum addrequest --help'
 * Commands can be called with jsonrpc, using the 'jsonrpc' gui. The
   jsonrpc interface may be called by php.

# Release 2.2
 * Show amounts (thousands separators and decimal point)
   according to locale in GUI
 * Show unmatured coins in balance
 * Fix exchange rates plugin
 * Network layer: refactoring and fixes

# Release 2.1.1
 * patch a bug that prevents new wallet creation.
 * fix connection issue on osx binaries

# Release 2.1
 * Faster startup, thanks to the following optimizations:
   1. Transaction input/outputs are cached in the wallet file
   2. Fast X509 certificate parser, not using pyasn1 anymore.
   3. The Label Sync plugin only requests modified labels.
 * The 'Invoices' and 'Send' tabs have been merged.
 * Contacts are stored in a separate file, shared between wallets.
 * A Search Box is available in the GUI (Ctrl-S)
 * Payment requests have an expiration date and can be exported to
   BIP70 files.
 * file: scheme support in BIP72 URIs: "bitcoin:?r=file:///..."
 * Own addresses are shown in green in the Transaction dialog.
 * Address History dialog.
 * The OpenAlias plugin was improved.
 * Various bug fixes and GUI improvements.
 * A new LabelSync backend is being used an import of the old
   database was made but since the release came later it's
   recommended that you do a full push when you upgrade.

# Release 2.0.4 - Minor GUI improvements
 * The password dialog will ask for password again if the user enters
   a wrong password
 * The Master Public Key dialog displays which keys belong to the
   wallet, and which are cosigners
 * The transaction dialog will ask to save unsaved transaction
   received from cosigner pool, when user clicks on 'Close'
 * The multisig restore dialog accepts xprv keys.
 * The network daemon must be started explicitly before using commands
   that require a connection
   Example:
     electrum daemon start
     electrum getaddressunspent <addr>
     electrum daemon status
     electrum daemon stop
   If a daemon is running, the GUI will use it.

# Release 2.0.3 - bugfixes and minor GUI improvements
 * Do not use daemon threads (fix #960)
 * Add a zoom button to receive tab
 * Add exchange rate conversion to receive tab
 * Use Tor's default port number in default proxy config

# Release 2.0.2 - bugfixes
 * Fix transaction sweep (#1066)
 * Fix thread timing bug (#1054)

# Release 2.0.1 - bugfixes
 * Fix critical bug in Trezor address derivation: passphrases were not
   NFKD normalized. Trezor users who created a wallet protected by a
   passphrase containing utf-8 characters with diacritics are
   affected. These users will have to open their wallet with version
   2.0 and to move their funds to a new wallet.
 * Use a file socket for the daemon (fixes network dialog issues)
 * Fix crash caused by QR scanner icon when zbar not installed.
 * Fix CosignerPool plugin
 * Label Sync plugin: Fix label sharing between multisig wallets


# Release 2.0

 * Before you upgrade, make sure you have saved your wallet seed on
   paper.

 * Documentation is now hosted on a wiki: http://electrum.orain.org

 * New seed derivation method (not compatible with BIP39). The seed
   phrase includes a version number, that refers to the wallet
   structure. The version number also serves as a checksum, and it
   will prevent the import of seeds from incompatible wallets. Old
   Electrum seeds are still supported.

 * New address derivation (BIP32). Standard wallets are single account
   and use a gap limit of 20.

 * Support for Multisig wallets using parallel BIP32 derivations and
   P2SH addresses ("2 of 2", "2 of 3").

 * Compact serialization format for unsigned or partially signed
   transactions, that includes the BIP32 master public key and
   derivation needed to sign inputs. Serialized transactions can be
   sent to cosigners or to cold storage using QR codes (using Andreas
   Schildbach's base 43 idea).

 * Support for BIP70 payment requests:
   - Verification of the chain of signatures uses tlslite.
   - In the GUI, payment requests are shown in the 'Invoices' tab.

 * Support for hardware wallets: Trezor (Satoshilabs) and Btchip (Ledger).

 * Two-factor authentication service by TrustedCoin. This service uses
   "2 of 3" multisig wallets and Google Authenticator. Note that
   wallets protected by this service can be deterministically restored
   from seed, without Trustedcoin's server.

 * Cosigner Pool plugin: encrypted communication channel for multisig
   wallets, to send and receive partially signed transactions.

 * Audio Modem plugin: send and receive transactions by sound.

 * OpenAlias plugin: send bitcoins to aliases verified using DNSSEC.

 * New 'Receive' tab in the GUI:
   - create and manage payment requests, with QR Codes
   - the former 'Receive' tab was renamed to 'Addresses'
   - the former Point of Sale plugin is replaced by a resizeable
     window that pops up if you click on the QR code

 * The 'Send' tab in the Qt GUI supports transactions with multiple
   outputs, and raw hexadecimal scripts.

 * The GUI can connect to the Electrum daemon: "electrum -d" will
   start the daemon if it is not already running, and the GUI will
   connect to it. The daemon can serve several clients. It times out
   if no client uses if for more than 5 minutes.

 * The install wizard can be used to import addresses or private
   keys. A watching-only wallet is created by entering a list of
   addresses in the wizard dialog.

 * New file format: Wallets files are saved as JSON. Note that new
   wallet files cannot be read by older versions of Electrum. Old
   wallet files will be converted to the new format; this operation
   may take some time, because public keys will be derived for each
   address of your wallet.

 * The client accepts servers with a CA-signed SSL certificate.

 * ECIES encrypt/decrypt methods, availabe in the GUI and using
   the command line:
      encrypt <pubkey> <message>
      decrypt <pubkey> <message>

 * The Android GUI has received various updates and it is much more
   stable. Another script was added to Android, called Authenticator,
   that works completely offline: it reads an unsigned transaction
   shown as QR code, signs it and shows the result as a QR code.


# Release 1.9.8

* Electrum servers were upgraded to version 0.9. The new server stores
  a Patrica tree of all UTXOs, an idea proposed by Alan Reiner in the
  bitcointalk forum. This property allows the client to directly
  request the balance of any address. The new commands are:
     1. getaddressbalance <address> 
     2. getaddressunspent <address>
     3. getutxoaddress <txid> <pos>

* Command-line commands that require a connection to the network spawn
  a daemon, that remains connected and handles subsequent
  commands. The daemon terminates itself if it remains unused for more
  than one minute. The purpose of this is to make scripting more
  efficient. For example, a bash script using many electrum commands
  will open only one connection.

# Release 1.9.7

* Fixed bug where never-confirmed transactions prevented further spending


# Release 1.7.4

* Increase default fee
* fix create and restore in command line

# Release 1.7.3:

* Classic GUI can display amounts in mBTC
* Account selector in the classic GUI
* Changed the way the portable flag uses without supplying a -w argument
* Classic GUI asks users to enter their seed on wallet creation


# Release 1.7.2:  

* Transactions that are in the same block are displayed in chronological order in the history.
* The client computes transaction priority and rejects zero-fee transactions that need a fee.
* The default fee was lowered to 200 uBTC per kb.
* Due to an internal format change, your history may be pruned when
  you open your wallet for the first time after upgrading to 1.7.2. If
  this is the case, please visit a full server to restore your full
  history. You will only need to do that once.


# Release 1.7.1:  bugfixes.


# Release 1.7

* The Classic GUI can be extended with plugins. Developers who want to
add new features or third-party services to Electrum are invited to
write plugins. Some previously existing and non-essential features of
Electrum (point-of-sale mode, qrcode scanner) were removed from the
core and are now available as plugins.

* The wallet waits for 2 confirmations before creating new
addresses. This makes recovery from seed more robust. Note that it
might create unwanted gaps if you use Electrum 1.7 together with older
versions of Electrum.

* An interactive Python console replaces the 'Wall' tab. The provided
python environment gives users access to the wallet and gui. Most
electrum commands are available as python function in the
console. Custom scripts an be loaded with a "run(filename)"
command. Tab-completions are available.

* The location of the Electrum folder in Windows changed from
LOCALAPPDATA to APPDATA. Discussion on this topic can be found here:
https://bitcointalk.org/index.php?topic=144575.0

* Private keys can be exported from within the classic GUI:
  For a single address, use the address menu (right-click).
  To export the keys of your entire wallet, use the settings dialog (import/export tab).

* It is possible to create, sign and redeem multisig transaction using the 
command line interface.  This is made possible by the following new commands:
    dumpprivkey, listunspent, createmultisig, createrawtransaction, decoderawtransaction, signrawtransaction
The syntax of these commands is similar to their bitcoind counterpart. 
For an example, see Gavin's tutorial: https://gist.github.com/gavinandresen/3966071

* Offline wallets now work in a way similar to Armory: 
  1. user creates an unsigned transaction using the online (watching-only) wallet.
  2. unsigned transaction is copied to the offline computer, and signed by the offline wallet.
  3. signed transaction is copied to the online computer, broadcasted by the online client.
  4. All these steps can be done via the command line interface or the classic GUI. 

* Many command line commands have been renamed in order to make the syntax consistent with bitcoind.
