RELEASE-NOTES

# Release 3.0.5 : (Security update)

This is a follow-up to the 3.0.4 release, which did not completely fix
issue #3374. Users should upgrade to 3.0.5.

 * The JSONRPC interface is password protected
 * JSONRPC commands are disabled if the GUI is running, except 'ping',
   which is used to determine if a GUI is already running


# Release 3.0.4 : (Security update)

 * Fix a vulnerability caused by Cross-Origin Resource Sharing (CORS)
   in the JSONRPC interface. Previous versions of Electrum are
   vulnerable to port scanning and deanonimization attacks from
   malicious websites. Wallets that are not password-protected are
   vulnerable to theft.
 * Bundle QR scanner with Android app
 * Minor bug fixes

# Release 3.0.3
  * Qt GUI: sweeping now uses the Send tab, allowing fees to be set
  * Windows: if using the installer binary, there is now a separate shortcut
    for "Electrum Testnet"
  * Digital Bitbox: added suport for p2sh-segwit
  * OS notifications for incoming transactions
  * better transaction size estimation:
    - fees for segwit txns were somewhat underestimated (#3347)
    - some multisig txns were underestimated
    - handle uncompressed pubkeys
  * fix #3321: testnet for Windows binaries
  * fix #3264: Ledger/dbb signing on some platforms
  * fix #3407: KeepKey sending to p2sh output
  * other minor fixes and usability improvements

# Release 3.0.2
  * Android: replace requests tab with address tab, with access to
    private keys
  * sweeping minikeys: search for both compressed and uncompressed
    pubkeys
  * fix wizard crash when attempting to reset Google Authenticator
  * fix #3248: fix Ledger+segwit signing
  * fix #3262: fix SSL payment request signing
  * other minor fixes.

# Release 3.0.1
  * minor bug and usability fixes

# Release 3.0 - Uncanny Valley (November 1st, 2017)

  * The project was migrated to Python3 and Qt5. Python2 is no longer
    supported. If you cloned the source repository, you will need to
    run "python3 setup.py install" in order to install the new
    dependencies.

  * Segwit support: 

    - Native segwit scripts are supported using a new type of
      seed. The version number for segwit seeds is 0x100. The install
      wizard will not create segwit seeds by default; users must
      opt-in with the segwit option.

    - Native segwit scripts are represented using bech32 addresses,
      following BIP173. Please note that BIP173 is still in draft
      status, and that other wallets/websites may not support
      it. Thus, you should keep a non-segwit wallet in order to be
      able to receive bitcoins during the transition period. If BIP173
      ends up being rejected or substantially modified, your wallet
      may have to be restored from seed. This will not affect funds
      sent to bech32 addresses, and it will not affect the capacity of
      Electrum to spend these funds.

    - Segwit scripts embedded in p2sh are supported with hardware
      wallets or bip39 seeds. To create a segwit-in-p2sh wallet,
      trezor/ledger users will need to enter a BIP49 derivation path.

    - The BIP32 master keys of segwit wallets are serialized using new
      version numbers. The new version numbers encode the script type,
      and they result in the following prefixes:

         * xpub/xprv : p2pkh or p2sh
         * ypub/yprv : p2wpkh-in-p2sh
         * Ypub/Yprv : p2wsh-in-p2sh
         * zpub/zprv : p2wpkh
         * Zpub/Zprv : p2wsh

      These values are identical for mainnet and testnet; tpub/tprv
      prefixes are no longer used in testnet wallets.

    - The Wallet Import Format (WIF) is similarly extended for segwit
      scripts. After a base58-encoded key is decoded to binary, its
      first byte encodes the script type:

         * 128 + 0: p2pkh
         * 128 + 1: p2wpkh
         * 128 + 2: p2wpkh-in-p2sh
         * 128 + 5: p2sh
         * 128 + 6: p2wsh
         * 128 + 7: p2wsh-in-p2sh

      The distinction between p2sh and p2pkh in private key means that
      it is not possible to import a p2sh private key and associate it
      to a p2pkh address.

  * A new version of the Electrum protocol is required by the client
    (version 1.1). Servers using older versions of the protocol will
    not be displayed in the GUI.

  * By default, transactions are time-locked to the height of the
    current block. Other values of locktime may be passed using the
    command line.


# Release 2.9.3
  * fix configuration file issue #2719
  * fix ledger signing of non-RBF transactions
  * disable 'spend confirmed only' option by default

# Release 2.9.2
  * force headers download if headers file is corrupted
  * add websocket to windows builds

# Release 2.9.1
  * fix initial headers download
  * validate contacts on import
  * command-line option for locktime

# Release 2.9 - Independence (July 27th, 2017)
  * Multiple Chain Validation: Electrum will download and validate
    block headers sent by servers that may follow different branches
    of a fork in the Bitcoin blockchain. Instead of a linear sequence,
    block headers are organized in a tree structure. Branching points
    are located efficiently using binary search. The purpose of MCV is
    to detect and handle blockchain forks that are invisible to the
    classical SPV model.
  * The desired branch of a blockchain fork can be selected using the
    network dialog. Branches are identified by the hash and height of
    the diverging block. Coin splitting is possible using RBF
    transaction (a tutorial will be added).
  * Multibit support: If the user enters a BIP39 seed (or uses a
    hardware wallet), the full derivation path is configurable in the
    install wizard.
  * Option to send only confirmed coins
  * Qt GUI:
    - Network dialog uses tabs and gets updated by network events.
    - The gui tabs use icons
  * Kivy GUI:
    - separation between network dialog and wallet settings dialog.
    - option for manual server entry
    - proxy configuration
  * Daemon: The wallet password can be passed as parameter to the
    JSONRPC API.
  * Various other bugfixes and improvements.


# Release 2.8.3
  * Fix crash on reading older wallet formats.
  * TrustedCoin: remove pay-per-tx option

# Release 2.8.2
  * show paid invoices in history tab
  * improve CPFP dialog
  * fixes for trezor, keepkey
  * other minor bugfixes

# Release 2.8.1
  * fix Digital Bitbox plugin
  * fix daemon jsonrpc
  * fix trustedcoin wallet creation
  * other minor bugfixes

# Release 2.8.0 (March 9, 2017)
  * Wallet file encryption using ECIES: A keypair is derived from the
    wallet password. Once the wallet is decrypted, only the public key
    is retained in memory, in order to save the encrypted file.
  * The daemon requires wallets to be explicitly loaded before
    commands can use them. Wallets can be loaded using: 'electrum
    daemon load_wallet [-w path]'. This command will require a
    password if the wallet is encrypted.
  * Invoices and contacts are stored in the wallet file and are no
    longer shared between wallets. Previously created invoices and
    contacts files may be imported from the menu.
  * Fees improvements:
    - Dynamic fees are enabled by default.
    - Child Pays For Parent (CPFP) dialog in the GUI.
    - RBF is automatically proposed for low fee transactions.
  * Support for Segregated Witness (testnet only).
  * Support for Digital Bitbox hardware wallet.
  * The GUI shows a blue icon when connected using a proxy.

  * Use fee slider for both static and dynamic fees.
  * Add fee slider to RBF dialog (fix #2083).
  * Simplify fee preferences.
  * Critical: Fix password update issue (#2097). This bug prevents
    password updates in multisig and 2FA wallets. It may also cause
    wallet corruption if the wallet contains several master private
    keys (such as 2FA wallets that have been restored from
    seed). Affected wallets will need to be restored again.

# Release 2.7.6
 * Fixes a critical bug with imported private keys (issue #1966). Keys
   imported in Electrum 2.7.x were not encrypted, even if the wallet
   had a password. If you imported private keys using Electrum 2.7.x,
   you will need to import those keys again. If you imported keys in
   2.6 and converted with 2.7.x, you don't need to do anything, but
   you still need to upgrade in order to be able to spend.
 * Wizard: Hide seed options in a popup dialog.

# Release 2.7.5
 * Add number of confirmations to request status. (issue #1757)
 * In the GUI, refer to passphrase as 'seed extension'.

# Release 2.7.1
 * fix wizard crash with old seeds
 * fix issue #1948: fee slider

# Release 2.7.0 (Oct 2 2016)

 * The wallet file format has been upgraded. This upgrade is not
   backward compatible, which means that a wallet upgraded to the 2.7
   format will not be readable by earlier versions of
   Electrum. Multiple accounts inside the same wallet are not
   supported in the new format; the Qt GUI will propose to split any
   wallet that has several accounts. Make sure that you have saved
   your seed phrase before you upgrade Electrum.
 * This version introduces a separation between wallets types and
   keystores types. 'Wallet type' defines the type of Bitcoin contract
   used in the wallet, while 'keystore type' refers to the method used
   to store private keys. Therefore, so-called 'hardware wallets' will
   be referred to as 'hardware keystores'.
 * Hardware keystores:
   - The Ledger Nano S is supported.
   - Hardware keystores can be used as cosigners in multi-signature
     wallets.
   - Multiple hardware cosigners can be used in the same multisig
     wallet. One icon per keystore is displayed in the satus bar. Each
     connected device will co-sign the transaction.
 * Replace-By-Fee: RBF transactions are supported in both Qt and
   Android. A warning is displayed in the history for transactions
   that are replaceable, have unconfirmed parents, or that have very
   low fees.
 * Dynamic fees: Dynamic fees are enabled by default. A slider allows
   the user to select the expected confirmation time of their
   transaction. The expected confirmation times of incoming
   transactions is also displayed in the history.
 * The install wizards of Qt and Kivy have been unified.
 * Qt GUI (Desktop):
   - A fee slider is visible in the in send tab
   - The Address tab is hidden by default, can be shown with Ctrl-A
   - UTXOs are displayed in the Address tab
 * Kivy GUI (Android):
   - The GUI displays the complete transaction history.
   - Multisig wallets are supported.
   - Wallets can be created and deleted in the GUI.
 * Seed phrases can be extended with a user-chosen passphrase. The
   length of seed phrases is standardized to 12 words, using 132 bits
   of entropy (including 2FA seeds). In the wizard, the type of the
   seed is displayed in the seed input dialog.
 * TrustedCoin users can request a reset of their Google Authenticator
   account, if they still have their seed.

   Privacy.
 * The install wizard has been rewritten and improved
 * Support minikeys as used in Casascius coins for private key import
   and sweeping
 * Much improved support for TREZOR and KeepKey devices:
   - full device information display
   - initialize a new or wiped device in 4 ways:
     1) device generates a new wallet
     2) you enter a seed
     3) you enter a BIP39 mnemonic to generate the seed
     4) you enter a master private key
   - KeepKey secure seed recovery (KeepKey only)
   - change / set / disable PIN
   - set homescreen (TREZOR only)
   - set a session timeout.  Once a session has timed out, further use
     of the device requires your PIN and passhphrase to be re-entered
   - enable / disable passphrases
   - device wipe
   - multiple device support

# Release 2.5.4

 * fix history bug #1479

# Release 2.5
 * Low-S values are used in signatures (BIP 62).
 * The Kivy GUI has been merged into master.
 * The Qt GUI supports multiple windows in the same process. When a
   new Electrum instance is started, it checks for an already running
   Electrum process, and connects to it.
 * The network layer uses select(), so all server communication is
   handled by a single thread. Moreover, the synchronizer, verifier,
   and exchange rate plugin now run as separate jobs within the
   networking thread instead of as their own threads.
 * Plugins are revamped, particularly the exchange rate plugin.

# Release 2.4.4
 * Fix bug with TrustedCoin plugin

# Release 2.4.3
 * Support for KeepKey hardware wallet
 * Simplified Chinese wordlist
 * Minor bugfixes and GUI tweaks

# Release 2.4.2

 * Various bugfixes

# Release 2.4.1
 * Use ssl.PROTOCOL_TLSv1
 * Fix DNSSEC issues with ECDSA signatures
 * Replace TLSLite dependency with minimal RSA implementation
 * Dynamic Fees: using estimatefee value returned by server
 * Various GUI improvements

# Release 2.4
 * Payment to DNS names storing a Bitcoin addresses (OpenAlias) is
   supported directly, without activating a plugin. The verification
   uses DNSSEC.
 * The DNSSEC verification code was rewritten. The previous code,
   which was part of the OpenAlias plugin, is vulnerable and should
   not be trusted (Electrum 2.0 to 2.3).
 * Payment requests can be signed using Bitcoin addresses stored
   in DNS (OpenAlias). The identity of the requestor is verified using
   DNSSEC.
 * Payment requests signed with OpenAlias keys can be shared as
   bitcoin: URIs, if they are simple (a single address-type
   output). The BIP21 URI scheme is extended with 'name', 'sig',
   'time', 'exp'.
 * Arbitrary m-of-n multisig wallets are supported (n<=15).
 * Multisig transactions can be signed with TREZOR. When you create
   the multisig wallet, just enter the xpub of your existing TREZOR
   wallet.
 * Transaction fees set manually in the GUI are retained, including
   when the user uses the '!' shortcut.
 * New 'email' plugin, that enables sending and receiving payment
   requests by email.
 * The daemon supports Websocket notifications of payments.

# Release 2.3.3
 * fix proxy settings (issue #1309)
 * improvements to the transaction dialog:
    - request password after showing transaction
    - show change addresses in yellow color

# Release 2.3.2
 * minor bugfixes
 * updated ledger plugin
 * sort inputs/outputs lexicographically (BIP-LI01)

# Release 2.3.1
 * patch a bug with payment requests

# 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
* Fix for offline signing
* Various bugfixes
* GUI usability improvements
* Coinbase Buyback plugin

# Release 1.9.6
* During wallet creation, do not write seed to disk until it is encrypted.
* Confirmation dialog if the transaction fee is higher than 1mBTC.
* bugfixes

* Put addresses that have been used in a minimized section (Qt GUI)
* Allow non ascii chars in passwords


# Release 1.9.4
bugfixes: offline transactions

# Release 1.9.3
bugfixes: connection problems, transactions staying unverified

# Release 1.9.2

# 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.
