* MacOS: support QR code scanner in binaries.
* Android APK:
- build using Google NDK instead of Crystax NDK
- target API 28
- do not use external storage (previously for block headers)

- Archos Safe-T mini: fix #4726 signing issue
- Trezor: refactoring and compat with python-trezor 0.11
- Digital BitBox: support firmware v5.0.0
* fix bitcoin URI handling when app already running (#4796)
* Qt listings rewritten:
the History tab now uses QAbstractItemModel, the other tabs use
QStandardItemModel. Performance should be better for large wallets.
* Several other minor bugfixes and usability improvements.

supplied via send tab, show extra payload info in tx dialog).
* Display DIP2 tx type in transaction history list (enabled in
appearance preferences).
* Support of DIP3 masternodes (new masternode manager and UI placed
in DIP3 tab, import legacy masternodes from wallet or conf file).
* Fix stdio and text wallet gui.
* Switch to electrum protocol 1.4, ElectrumX>=1.9.1 recommended to
support DIP3 electrum protocol methods.

add docs to setup Tor Proxy on other platforms. Warning if run without Tor.
# Release 3.2.3
* hardware wallet: the Safe-T mini from Archos is now supported.
* BIP39 seeds: if a seed extension (aka passphrase) contained
multiple consecutive whitespaces or leading/trailing whitespaces
then the derived addresses were not following spec. This has been
fixed, and affected should move their coins. The wizard will show a
warning in this case. (#4566)
* Revealer: the PRNG used has been changed (#4649)
* fix Linux distributables: 'typing' was not bundled, needed for python 3.4
* fix #4491: on Android, if user had set "uAXE" as base unit, app crashed
* fix #4497: on Android, paying bip70 invoices from cold start did not work
* Several other minor bugfixes and usability improvements.
# Release 3.2.2.1
* PPA built with libsecp256k1-0, python3-pycryptodome dependencies
* Added dark theme
* Fix ecc_fast.py for win64
* Fix vcrun2015 in win64 builds
# Release 3.2.2
* Fix DNS resolution on Windows
* Fix websocket bug in daemon
# Release 3.2.1
* fix Windows binaries: due to build process changes, the locale files
were not included; the language could not be changed from English
* fix Linux distributables: wordlists were not included (#4475)
# Release 3.2.0
* If present, libsecp256k1 is used to speed up elliptic curve
operations. The library is bundled in the Windows, MacOS, and
Android binaries. On Linux, it needs to be installed separately.
* Two-factor authentication is available on Android. Note that this
will only provide additional security if one time passwords are
generated on a separate device.
* Semi-automated crash reporting is implemented for Android.
* Transactions that are dropped from the mempool are kept in the
wallet as 'local', and can be rebroadcast. Previously these
transactions were deleted from the wallet.
* The scriptSig part of transaction inputs are no longer
parsed, unless actually needed. The wallet will no longer display
'from' addresses corresponding to transaction inputs, except for
its own inputs.
* The partial transaction format has been incompatibly changed. This
was needed as for partial transactions the scriptSig has to
be parsed, but for signed transactions we did not want to do the
parsing. Users should make sure that all instances of Electrum
they use to co-sign or offline sign, are updated together.
* Signing of partial transactions created with online imported
addresses wallets now supports significantly more
setups. Previously only online p2pkh address + offline WIF was
supported. Now the following setups are all supported:
- online p2pkh address + offline WIF,
- online p2pkh address + offline seed/xprv,
- online p2sh-multisig address + offline seeds/xprvs
(potentially distributed among several different machines)
Note that for the online address + offline HD secret case, you need
the offline wallet to recognize the address (i.e. within gap
limit). Having an xpub on the online machine is still the
recommended setup, as this allows the online machine to generate
new addresses on demand.
* Added Revealer plugin. ( https://revealer.cc ) Revealer is a seed
phrase back-up solution. It allows you to create a cold, analog,
multi-factor backup of your wallet seeds, or of any arbitrary
secret. The Revealer utilizes a transparent plastic visual one time
pad.
* Hardware wallets: a "show address" button is now displayed in the
Receive tab of the Qt GUI. (#4316)
* Trezor One: implemented advanced/matrix recovery (#4329)
* Qt/Kivy: added "hak" as optional base unit.
* Kivy GUI: significant performance improvements when displaying
history and address list of large wallets; and transaction dialog
of large transactions.
* Windows: use dnspython to resolve dns instead of socket.getaddrinfo
(#4422)
* Importing minikeys: use uncompressed pubkey instead of compressed
(#4384)
* SPV proofs: check inner nodes not to be valid transactions (#4436)
* Several other minor bugfixes and usability improvements.
# Release 3.1.3
* Qt GUI: seed word auto-complete during restore
* Android: fix some crashes
* performance improvements (wallet, and Qt GUI)
* hardware wallets: show debug message during device scan
* add regtest support (via --regtest flag)

# Release 3.1.2
* Kivy/android: request PIN on startup
* Fix various bugs with hardware wallets
* Other minor bugfixes
# Release 3.1.1
* fix #4031: Trezor T support
* partial fix #4060: proxy and hardware wallet can't be used together
* fix #4039: can't set address labels
* fix crash related to coinbase transactions
* MacOS: use internal graphics card
* fix openalias related crashes
* speed-up capital gains calculations
* hw wallet encryption: re-prompt for passphrase if incorrect
* other minor fixes.
# Release 3.1.0
* Capital gains: For each outgoing transaction, the difference
between the acquisition and liquidation prices of outgoing coins is
displayed in the wallet history. By default, historical exchange
rates are used to compute acquisition and liquidation prices. These
values can also be entered manually, in order to match the actual
price realized by the user. The order of liquidation of coins is
the natural order defined by the blockchain; this results in
capital gain values that are invariant to changes in the set of
addresses that are in the wallet. Any other ordering strategy (such
as FIFO, LIFO) would result in capital gain values that depend on
the presence of other addresses in the wallet.
* Local transactions: Transactions can be saved in the wallet without
being broadcast. The inputs of local transactions are considered as
spent, and their change outputs can be re-used in subsequent
transactions. This can be combined with cold storage, in order to
create several transactions before broadcasting them. Outgoing
transactions that have been removed from the memory pool are also
saved in the wallet, and can be broadcast again.
* Checkpoints: The initial download of a headers file was replaced
with hardcoded checkpoints. The wallet uses one checkpoint per
retargeting period. The headers for a retargeting period are
downloaded only if transactions need to be verified in this period.
* The 'privacy' and 'priority' coin selection policies have been
merged into one. Previously, the 'privacy' policy has been unusable
because it was was not prioritizing confirmed coins. The new policy
is similar to 'privacy', except that it de-prioritizes addresses
that have unconfirmed coins.
* The 'Send' tab of the Qt GUI displays how transaction fees are
computed from transaction size.
* The wallet history can be filtered by time interval.
* Watching-only wallets and hardware wallets can be encrypted.
* Semi-automated crash reporting
* The SSL checkbox option was removed from the GUI.
* The Trezor T hardware wallet is now supported.
* Windows: the binaries now include ZBar, and QR code scanning should work.
* The Wallet Import Format (WIF) for private keys that was extended in 3.0
is changed. Keys in the previous format can be imported, compatibility
is maintained. Newly exported keys will be serialized as
"script_type:original_wif_format_key".
* A new version of the Electrum protocol is required by the client
(version 1.2). Servers using older versions of the protocol will
not be displayed in the GUI.

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

# 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.
* 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 2.9.4 (security update)
* Incorporate electrum 2.9.4 changes
# Release 2.9.3.2 (Security update)
* 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
* Fix hardware wallets supoort for Windows/OSX builds
# Release 2.9.3.1 (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.
# Release 2.9.3

# Release 2.9.2
* force headers download if headers file is corrupted
* add websocket to windows builds
# Release 2.9.1

# 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.
* 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

# 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.
* Support for Digital Bitbox hardware wallet.
* The GUI shows a blue icon when connected using a proxy.

* Ledger: new ui and mobile 2fa validation (neocogent)
# Release 2.7.15
* Use fee slider for both static and dynamic fees.
* 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.

* 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

# 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.
* 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. Enable it by setting the Coin Selection preference to
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

* 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.

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)

# 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
