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.

* 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.

* 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

# 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.

* 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.
