-# Code of Conduct
-
-## 1. Purpose
-
-A primary goal of Parity is to be inclusive to the largest number of contributors, with the most varied and diverse backgrounds possible. As such, we are committed to providing a friendly, safe and welcoming environment for all, regardless of gender, sexual orientation, ability, ethnicity, socioeconomic status, and religion (or lack thereof).
-
-This code of conduct outlines our expectations for all those who participate in our community, as well as the consequences for unacceptable behavior.
-
-We invite all those who participate in Parity to help us create safe and positive experiences for everyone.
-
-## 2. Open Source Citizenship
-
-A supplemental goal of this Code of Conduct is to increase open source citizenship by encouraging participants to recognize and strengthen the relationships between our actions and their effects on our community.
-
-Communities mirror the societies in which they exist and positive action is essential to counteract the many forms of inequality and abuses of power that exist in society.
-
-If you see someone who is making an extra effort to ensure our community is welcoming, friendly, and encourages all participants to contribute to the fullest extent, we want to know.
-
-## 3. Expected Behavior
-
-The following behaviors are expected and requested of all community members:
-
-*   Participate in an authentic and active way. In doing so, you contribute to the health and longevity of this community.
-*   Exercise consideration and respect in your speech and actions.
-*   Attempt collaboration before conflict.
-*   Refrain from demeaning, discriminatory, or harassing behavior and speech.
-*   Be mindful of your surroundings and of your fellow participants. Alert community leaders if you notice a dangerous situation, someone in distress, or violations of this Code of Conduct, even if they seem inconsequential.
-*   Remember that community event venues may be shared with members of the public; please be respectful to all patrons of these locations.
-
-## 4. Unacceptable Behavior
-
-The following behaviors are considered harassment and are unacceptable within our community:
-
-*   Violence, threats of violence or violent language directed against another person.
-*   Sexist, racist, homophobic, transphobic, ableist or otherwise discriminatory jokes and language.
-*   Posting or displaying sexually explicit or violent material.
-*   Posting or threatening to post other people’s personally identifying information ("doxing").
-*   Personal insults, particularly those related to gender, sexual orientation, race, religion, or disability.
-*   Inappropriate photography or recording.
-*   Inappropriate physical contact. You should have someone’s consent before touching them.
-*   Unwelcome sexual attention. This includes, sexualized comments or jokes; inappropriate touching, groping, and unwelcomed sexual advances.
-*   Deliberate intimidation, stalking or following (online or in person).
-*   Advocating for, or encouraging, any of the above behavior.
-*   Sustained disruption of community events, including talks and presentations.
-
-## 5. Consequences of Unacceptable Behavior
-
-Unacceptable behavior from any community member, including sponsors and those with decision-making authority, will not be tolerated.
-
-Anyone asked to stop unacceptable behavior is expected to comply immediately.
-
-If a community member engages in unacceptable behavior, the community organizers may take any action they deem appropriate, up to and including a temporary ban or permanent expulsion from the community without warning (and without refund in the case of a paid event).
-
-## 6. Reporting Guidelines
-
-If you are subject to or witness unacceptable behavior, or have any other concerns, please notify a community organizer as soon as possible. community@parity.io.
-
-Link to reporting guidelines: [CONTRIBUTING.md](CONTRIBUTING.md)
-
-Link to security policy: [SECURITY.md](../SECURITY.md)
-
-Additionally, community organizers are available to help community members engage with local law enforcement or to otherwise help those experiencing unacceptable behavior feel safe. In the context of in-person events, organizers will also provide escorts as desired by the person experiencing distress.
-
-## 7. Addressing Grievances
-
-If you feel you have been falsely or unfairly accused of violating this Code of Conduct, you should notify Parity Technologies with a concise description of your grievance. Your grievance will be handled in accordance with our existing governing policies.
-
-## 8. Scope
-
-We expect all community participants (contributors, paid or otherwise; sponsors; and other guests) to abide by this Code of Conduct in all community venues–online and in-person–as well as in all one-on-one communications pertaining to community business.
-
-This code of conduct and its related procedures also applies to unacceptable behavior occurring outside the scope of community activities when such behavior has the potential to adversely affect the safety and well-being of community members.

-## Parity-Ethereum [v2.0.0](https://github.com/paritytech/parity-ethereum/releases/tag/v2.0.0) "Ethereum" (2018-07-18)
-
-This is the Parity-Ethereum//v2.0.0-beta release, code-named "Ethereum", **YOLO!**
-
-Please note, Parity-Ethereum//v2.0.0 comes with some breaking changes that might be interrupting your usual workflows. Please mind them before upgrading:
-
-- The Parity client is now called _Parity-Ethereum_ to distinguish it from other software we provide, such as [_Parity-Bitcoin_](https://github.com/paritytech/parity-bitcoin/) and [_Parity-Polkadot_](https://github.com/paritytech/polkadot) ([#9052](https://github.com/paritytech/parity-ethereum/pull/9052)).
-- The public node and the user interface (a.k.a. _"Parity Wallet"_) are completely removed from the Parity-Ethereum//v2.0.0 client ([#8758](https://github.com/paritytech/parity-ethereum/pull/8758), [#8783](https://github.com/paritytech/parity-ethereum/pull/8783), [#8641](https://github.com/paritytech/parity-ethereum/pull/8641)). Users interested running a Parity Wallet, check out [the stand-alone UI application](https://github.com/Parity-JS/shell/releases).
-- The DApps subsystem was completely removed from the client ([#9017](https://github.com/paritytech/parity-ethereum/pull/9017), [#9107](https://github.com/paritytech/parity-ethereum/pull/9107)). Again, use the standalone wallet if you wish to continue working with them.
-- Windows and MacOS versions are not available as installer anymore and the system trays were removed ([#8778](https://github.com/paritytech/parity-ethereum/pull/8778)). If you desire to run Parity-Ethereum on Windows or MacOS, you still can get the binaries from our mirrors. Furthermore, MacOS users are encouraged [to use our homebrew tap](https://github.com/paritytech/homebrew-paritytech/).
-- Linux versions are not available as deb-/rpm-packages anymore ([#8887](https://github.com/paritytech/parity-ethereum/pull/8887)). Communities are encouraged to provide their own packages or maintain their own repositories, such as [Arch Linux does](https://www.archlinux.org/packages/community/x86_64/parity/) for instance.
-- MD5-checksums are completely replaced by SHA256-checksums ([#8884](https://github.com/paritytech/parity-ethereum/pull/8884)). This is also reflected on our homepage by now.
-- Deprecated, removed, or replaced CLI-options are hidden from client `--help` to further discourage their usage ([#8967](https://github.com/paritytech/parity-ethereum/pull/8967)).
-
-Additional noteworthy changes to the client:
-
-- Tracing of precompiled contracts when the transfer value is not zero ([#8486](https://github.com/paritytech/parity-ethereum/pull/8486))
-- _Parity-Ethereum_ as a library now provides APIs for running full and light nodes and a C interface ([#8412](https://github.com/paritytech/parity-ethereum/pull/8412)). Shared crates are now available in [_Parity-Common_](https://github.com/paritytech/parity-common) ([#9083](https://github.com/paritytech/parity-ethereum/pull/9083)).
-- The Morden database and keys are now moved to a `./Morden` subdirectory instead of `./test` which is by default used by Ropsten ([#8621](https://github.com/paritytech/parity-ethereum/pull/8621)).
-- Adding support for having an on-chain contract calculating the block rewards ([#8419](https://github.com/paritytech/parity-ethereum/pull/8419)).
-- Enforcing warp-only synchronization with `--warp-barrier [blocknumber]` flag ([#8228](https://github.com/paritytech/parity-ethereum/pull/8228)).
-- Adding a fork-choice and meta-data framework suitable for implementing Casper ([#8401](https://github.com/paritytech/parity-ethereum/pull/8401)).
-- Returning an error if RLP-size of a transaction exceeds a 300kB limit ([#8473](https://github.com/paritytech/parity-ethereum/pull/8473)).
-- Warp-sync is now resumable by keeping the downloaded chunks between client restarts. Also, it seeds downloaded snapshots for other nodes ([#8544](https://github.com/paritytech/parity-ethereum/pull/8544)).
-- The developer chain `--chain dev` now contains Byzantium features, this breaks existing developer chains ([#8717](https://github.com/paritytech/parity-ethereum/pull/8717)).
-- The EIP150, EIP160 and EIP161 forks are now to be specified in common params section of a chain-spec file instead of the Ethash params to enable these features on non-proof-of-work chains ([#8614](https://github.com/paritytech/parity-ethereum/pull/8614)). Please update your chain specs.
-- Allowing to disable local-by-default for transactions with new configurations ([#8882](https://github.com/paritytech/parity-ethereum/pull/8882)).
-- Never drop local transactions from different senders ([#9002](https://github.com/paritytech/parity-ethereum/pull/9002)).
-- Optimize pending transactions filter and fix ethstats reporting of pending transactions ([#9026](https://github.com/paritytech/parity-ethereum/pull/9026)).
-- Add separate database directory for light client allowing to run full and light nodes at the same time ([#9064](https://github.com/paritytech/parity-ethereum/pull/9064)).
-
-If you are upgrading directly from versions 1.10.9 or earlier, please note important changes to our transaction-queue implementation, namely:
-
-- The pool now limits transactions per-sender (see `--tx-queue-per-sender`), local transactions also have to obey that limit. Consider increasing the limit via CLI-flag when running benchmarks or sending a lot of transactions at once.
-- In case the pool is full, transactions received over the network, but originating from accounts that you have private keys for might not get accepted to the pool any more with higher priority. Consider running with larger pool size or submitting the transactions directly on the node via `eth_sendRawTransaction`.

-**Built for mission-critical use**: Miners, service providers, and exchanges need fast synchronisation and maximum uptime. Parity Ethereum provides the core infrastructure essential for speedy and reliable services.
+### Building from source
 
-- Clean, modular codebase for easy customisation
-- Advanced CLI-based client
-- Minimal memory and storage footprint
-- Synchronise in hours, not days with Warp Sync
-- Modular for light integration into your service or product
-
-## Technical Overview
-
-Parity Ethereum's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity Ethereum using the sophisticated and cutting-edge **Rust programming language**. Parity Ethereum is licensed under the GPLv3 and can be used for all your Ethereum needs.
-
-By default, Parity Ethereum runs a JSON-RPC HTTP server on port `:8545` and a Web-Sockets server on port `:8546`. This is fully configurable and supports a number of APIs.
-
-If you run into problems while using Parity Ethereum, check out the [wiki for documentation](https://wiki.parity.io/), feel free to [file an issue in this repository](https://github.com/paritytech/parity-ethereum/issues/new), or hop on our [Gitter](https://gitter.im/paritytech/parity) or [Riot](https://riot.im/app/#/group/+parity:matrix.parity.io) chat room to ask a question. We are glad to help! **For security-critical issues**, please refer to the security policy outlined in [SECURITY.md](SECURITY.md).
-
-Parity Ethereum's current beta-release is 2.1. You can download it at [the releases page](https://github.com/paritytech/parity-ethereum/releases) or follow the instructions below to build from source. Please, mind the [CHANGELOG.md](CHANGELOG.md) for a list of all changes between different versions.
-
-## Build Dependencies
-
-Parity Ethereum requires **Rust version 1.29.x** to build.
-
-We recommend installing Rust through [rustup](https://www.rustup.rs/). If you don't already have `rustup`, you can install it like this:
+First (if you don't already have it) get multirust:
 
 - Linux:
-  ```bash
-  $ curl https://sh.rustup.rs -sSf | sh
-  ```
+```bash
+curl -sf https://raw.githubusercontent.com/brson/multirust/master/quick-install.sh | sudo sh -s -- --yes
+```
 
-  Parity Ethereum also requires `gcc`, `g++`, `libudev-dev`, `pkg-config`, `file`, `make`, and `cmake` packages to be installed.
+- OSX with Homebrew:
+```bash
+brew update && brew install multirust
+multirust default stable
+```
 
-- OSX:
-  ```bash
-  $ curl https://sh.rustup.rs -sSf | sh
-  ```
-
-  `clang` is required. It comes with Xcode command line tools or can be installed with homebrew.
-
-- Windows
-  Make sure you have Visual Studio 2015 with C++ support installed. Next, download and run the `rustup` installer from
-  https://static.rust-lang.org/rustup/dist/x86_64-pc-windows-msvc/rustup-init.exe, start "VS2015 x64 Native Tools Command Prompt", and use the following command to install and set up the `msvc` toolchain:
-  ```bash
-  $ rustup default stable-x86_64-pc-windows-msvc
-  ```
-
-Once you have `rustup` installed, then you need to install:
-* [Perl](https://www.perl.org)
-* [Yasm](https://yasm.tortall.net)
-
-Make sure that these binaries are in your `PATH`. After that, you should be able to build Parity Ethereum from source.
-
-## Build from Source Code
+Then, download and build Parity:
 
 ```bash
-# download Parity Ethereum code
-$ git clone https://github.com/paritytech/parity-ethereum
-$ cd parity-ethereum
+# download Parity code
+git clone https://github.com/ethcore/parity
+cd parity
 
 # build in release mode
-$ cargo build --release --features final
+cargo build --release
 ```
-
-This produces an executable in the `./target/release` subdirectory.
-
-Note: if cargo fails to parse manifest try:
-
-```bash
-$ ~/.cargo/bin/cargo build --release
-```
-
-Note, when compiling a crate and you receive errors, it's in most cases your outdated version of Rust, or some of your crates have to be recompiled. Cleaning the repository will most likely solve the issue if you are on the latest stable version of Rust, try:
-
-```bash
-$ cargo clean
-```
-
-This always compiles the latest nightly builds. If you want to build stable or beta, do a
-
-```bash
-$ git checkout stable
-```
-
-or
-
-```bash
-$ git checkout beta
-```
-
-## Simple One-Line Installer for Mac and Linux
-
-```bash
-bash <(curl https://get.parity.io -L)
-```
-
-The one-line installer always defaults to the latest beta release. To install a stable release, run:
-
-```bash
-bash <(curl https://get.parity.io -L) -r stable
-```
-
-## Start Parity Ethereum
-
-### Manually
-
-To start Parity Ethereum manually, just run
-
-```bash
-$ ./target/release/parity
-```
-
-so Parity Ethereum begins syncing the Ethereum blockchain.
-
-### Using `systemd` service file
-
-To start Parity Ethereum as a regular user using `systemd` init:
-
-1. Copy `./scripts/parity.service` to your
-`systemd` user directory (usually `~/.config/systemd/user`).
-2. To configure Parity Ethereum, write a `/etc/parity/config.toml` config file, see [Configuring Parity Ethereum](https://paritytech.github.io/wiki/Configuring-Parity) for details.
-
-## Parity Ethereum toolchain
-
-In addition to the Parity Ethereum client, there are additional tools in this repository available:
-
-- [evmbin](https://github.com/paritytech/parity-ethereum/blob/master/evmbin/) - EVM implementation for Parity Ethereum.
-- [ethabi](https://github.com/paritytech/ethabi) - Parity Ethereum function calls encoding.

-# Security Policy
-
-Parity Technologies is committed to resolving security vulnerabilities in our software quickly and carefully. We take the necessary steps to minimize risk, provide timely information, and deliver vulnerability fixes and mitigations required to address security issues.
-
-## Reporting a Vulnerability
-
-Security vulnerabilities in Parity software should be reported by email to security@parity.io. If you think your report might be eligible for the Parity Bug Bounty Program, your email should be send to bugbounty@parity.io. 
-
-Your report should include the following:
-
-- your name
-- description of the vulnerability
-- attack scenario (if any)
-- components
-- reproduction
-- other details
-
-Try to include as much information in your report as you can, including a description of the vulnerability, its potential impact, and steps for reproducing it. Be sure to use a descriptive subject line.
-
-You'll receive a response to your email within two business days indicating the next steps in handling your report. We encourage finders to use encrypted communication channels to protect the confidentiality of vulnerability reports. You can encrypt your report using our public key. This key is [on MIT's key server](https://pgp.mit.edu/pks/lookup?op=get&search=0x5D0F03018D07DE73) server and reproduced below.
-
-After the initial reply to your report, our team will endeavor to keep you informed of the progress being made towards a fix. These updates will be sent at least every five business days. 
-
-Thank you for taking the time to responsibly disclose any vulnerabilities you find.
-
-## Responsible Investigation and Reporting
-
-Responsible investigation and reporting includes, but isn't limited to, the following:
-
-- Don't violate the privacy of other users, destroy data, etc.
-- Don’t defraud or harm Parity Technologies Ltd or its users during your research; you should make a good faith effort to not interrupt or degrade our services.
-- Don't target our physical security measures, or attempt to use social engineering, spam, distributed denial of service (DDOS) attacks, etc.
-- Initially report the bug only to us and not to anyone else.
-- Give us a reasonable amount of time to fix the bug before disclosing it to anyone else, and give us adequate written warning before disclosing it to anyone else.
-- In general, please investigate and report bugs in a way that makes a reasonable, good faith effort not to be disruptive or harmful to us or our users. Otherwise your actions might be interpreted as an attack rather than an effort to be helpful.
-
-## Bug Bounty Program
-
-Our Bug Bounty Program allows us to recognise and reward members of the Parity community for helping us find and address significant bugs, in accordance with the terms of the Parity Bug Bounty Program. A detailed description on eligibility, rewards, legal information and terms & conditions for contributors can be found on [our website](https://paritytech.io/bug-bounty.html).

-## Parity [v1.10.0](https://github.com/paritytech/parity/releases/tag/v1.10.0) (2018-03-22)
-
-This is the Parity 1.10.0-beta release! Cool!
-
-### Disabling the Parity Wallet
-
-The **Parity Wallet (a.k.a. "UI") is now disabled by default**. We are preparing to split the wallet from the core client.
-
-To reactivate the parity wallet, you have to run Parity either with `parity --force-ui` (not recommended) or `parity ui` (deprecated) from the command line. Or, if you feel super fancy and want to test our pre-releases of the stand-alone electron wallet, head over to the [Parity-JS repositories and check the releases](https://github.com/Parity-JS/shell/releases).

-
-### Introducing the Wasm VM
-
-We are excited to announce support for **Wasm Smart Contracts on Kovan network**. The hard-fork to activate the Wasm-VM will take place on block `6_600_000`.
-
-To enable Wasm contracts on your custom network, just schedule a `wasmActivationTransition` at your favorite block number (e.g., `42`, `666`, or `0xbada55`). To hack your first Wasm smart contracts in Rust, have a look at the [Parity Wasm Tutorials](https://github.com/paritytech/pwasm-tutorial).

-
-### Empty step messages in PoA
-
-To **reduce blockchain bloat, proof-of-authority networks can now enable _empty step messages_ which replace empty blocks**. Each step message will be signed and broadcasted by the issuing authorities, and included and rewarded in the next non-empty block.
-
-To enable empty step messages, set the `emptyStepsTransition` to your favorite block number. You can also specify a maximum number of empty steps with `maximumEmptySteps` in your chain spec.
-
-### Other noteworthy changes
-
-We removed the old database migrations from 2016. In case you upgrade Parity from a really, really old version, you will have to reset your database manually first with `parity <options> db kill`.
-
-We fixed  DELEGATECALL `from` and `to` fields, see [#7166](https://github.com/paritytech/parity/issues/7166).
-
-We reduced the default USD per transaction value to 0.0001. Thanks, @MysticRyuujin!
-
-The Musicoin chain is now enabled with Byzantium features starting at block `2_222_222`.

-## Parity [v1.11.7](https://github.com/paritytech/parity-ethereum/releases/tag/v1.11.7) "Prosperity" (2018-07-17)
-
-Parity 1.11.7 "Prosperity" is a bug-fix release to improve performance and stability that marks the 1.11 release track as `stable`. Among other fixes, this release significantly addresses peering and synchronization issues. If you experienced such issues before, upgrading is highly recommended. If you rely on old versions of Parity, check out the `old-stable-1.10` branch, cherry-pick fixes, and compile your binaries independently. There will be no official support for any versions prior to 1.11.7, however (EOL).
-
-If you are upgrading directly from versions 1.10.9 or earlier, please note important changes to our transaction-queue implementation, namely:
-
-- The pool now limits transactions per-sender (see `--tx-queue-per-sender`), local transactions also have to obey that limit. Consider increasing the limit via CLI-flag when running benchmarks or sending a lot of transactions at once.
-- In case the pool is full, transactions received over the network, but originating from accounts that you have private keys for might not get accepted to the pool any more with higher priority. Consider running with larger pool size or submitting the transactions directly on the node via `eth_sendRawTransaction`.

-## Parity [v1.11.1](https://github.com/paritytech/parity/releases/tag/v1.11.1) (2018-05-15)
-
-This is the Parity 1.11.1-beta release! Hurray!
-
-Notable changes in reversed alphabetical order:
-
-- TOOLING: **Whisper CLI** [#8201](https://github.com/paritytech/parity/pull/8201)
-  - `whisper-cli` is a standalone tool to communicate with the Whisper protocol.
-  - It provides functionality to specify `whisper-pool-size`, `port` and `address` to use.
-  - All whisper RPC APIs are enabled and can be directly accessed.
-- JSON-RPC API: **Return error in case eth_call returns VM errors** [#8448](https://github.com/paritytech/parity/pull/8448)
-  - This changes the behaviors of `eth_call` to respect VM errors if any.
-  - In case of `REVERT`, it will also return the reverted return data in hex format.
-- ENGINES: **Block Reward Contract** [#8419](https://github.com/paritytech/parity/pull/8419)
-  - The _AuRa_ PoA engine has now support for having a contract to calculate the block rewards.
-  - The engine passes a list of benefactors and reward types to the contract which then returns a list of addresses and respective rewards.
-- CORE: **Private Transactions** [#6422](https://github.com/paritytech/parity/pull/6422)
-  - Parity now provides a private transactions system.
-  - Please, check out our wiki to get an [overview and setup instructions](https://wiki.parity.io/Private-Transactions.html).
-- CORE: **New Transaction Queue implementation** [#8074](https://github.com/paritytech/parity/pull/8074)
-  - Verification is now done in parallel.
-  - Previous queue had `O(1)` time to get pending set, but `O(n^2)` insertion time. And obviously insertion/removal happens much more often than retrieving the pending set (only for propagation and pending block building) Currently we have `O(n * log(senders))` pending set time (with cache) and `O(tx_per_sender)` (usually within `log(tx_per_sender)`) insertion time.
-  - `Scoring` and `Readiness` are separated from the pool, so it's easier to customize them or introduce different definitions (for instance for [EIP-859](https://github.com/ethereum/EIPs/issues/859) or private transactions, etc).
-  - Banning removed, soft-penalization introduced instead: if transaction exceeds the limit other transactions from that sender get lower priority.
-  - There is no explicit distinction between current and future transactions in the pool - `Readiness` determines that. Because of this we additionally remove `future` transactions that occupy the pool for long time.
-- CONFIGURATION: **Warp-only sync with --warp-barrier [block-number] flag.** [#8228](https://github.com/paritytech/parity/pull/8228)
-  - Enables warp-only sync in case `--warp-barrier [block-number]` is provided.
-  - This avoids clients to warp to outdated snapshots that are too far away from the best block.
-  - This avoids clients to fall back to normal sync if there are no recent snapshots available currently.
-- CONFIGURATION: **Disable UI by default.** [#8105](https://github.com/paritytech/parity/pull/8105)
-  - The user interface is now disabled by default. It still can be activated with the `--force-ui` flag.
-  - To get the stand-alone Parity UI, please check the dedicated [releases page](https://github.com/parity-js/shell/releases).
-- CONFIGURATION: **Auto-updater improvements** [#8078](https://github.com/paritytech/parity/pull/8078)
-  - Added `--auto-update-delay` to randomly delay updates by `n` blocks. This takes into account the number of the block of the update release (old updates aren't delayed).
-  - Added `--auto-update-check-frequency` to define the periodicity of auto-update checks in number of blocks.
-  - This is an important improvement to ensure the network does not update all clients at the same time.
-- CHAIN SPECS: **Enable WebAssembly and Byzantium for Ellaism** [#8520](https://github.com/paritytech/parity/pull/8520)
-  - This activates the Ellaism Byzantium hardfork ([2018-0004-byzantium](https://github.com/ellaism/specs/blob/master/specs/2018-0004-byzantium.md)) at block `2_000_000`.
-  - This enables the Wasm VM on Ellaism ([2018-0003-wasm-hardfork](https://github.com/ellaism/specs/blob/master/specs/2018-0003-wasm-hardfork.md)) at block `2_000_000`.
-  - Please, upgrade your clients if you run an Ellaism configuration.
-- CHAIN SPECS: **Dev chain - increase gasLimit to 8_000_000** [#8362](https://github.com/paritytech/parity/pull/8362)
-  - This increases the default block gas limit on development chains to `8_000_000`.
-  - Please note, this makes previous dev chain configurations incompatible.
-- CHAIN SPECS: **Add MCIP-6 Byzyantium transition to Musicoin spec** [#7841](https://github.com/paritytech/parity/pull/7841)
-  - This activates the Musicoin Byzantium hardfork ([MCIP-6](https://github.com/Musicoin/MCIPs/blob/master/MCIPS/mcip-6.md)) at block `2_222_222`.
-  - Please, upgrade your clients if you run a Musicoin configuration.

-## Parity [v1.2.3](https://github.com/paritytech/parity/releases/tag/v1.2.3) (2016-07-31)
-
-Parity 1.2.3 is a patch release that addresses network stability issues for both Ethereum HF and Ethereum classic chains and brings a few changes to the transaction tracing API.
-
-#### Tracing API changes
-- Added tracing for `CALLCODE`, `DELEGATECALL` and `SUICIDE`
-- `trace_call` returns traces in flat format
-- Added 2 new methods: `trace_rawTransaction` and `trace_replayTransaction`
-
-Note that to continue using tracing features in this version you need to re-sync the blockchain. This can be done by using `parity export $HOME/ethereum-chain-backup.rlp` , deleting the database usually located at `~/.parity/906a34e69aec8c0d` followed by `parity import $HOME/ethereum-chain-backup.rlp`.

-## Parity [v1.2.1](https://github.com/paritytech/parity/releases/tag/v1.2.1) (2016-07-01)
-
-#### New
-- Options for more precise mining tuning (see below).
-- Informative notification when block mined.
-- HTTP signal on new work-package.
-- Optimised database insertion for self-mined blocks.
-- Short-circuit for local transaction gas-price approval.
-- A number of issues related to mining have been fixed.
-
-##### Mining options
-- `--author` is now required for mining.
-- `--reseal-on-txs` Specify which transactions should force the node to reseal a block. By default parity updates the seal on incoming transactions to reduce transaction latency. Set this option to `none` to force updates on new blocks only.
-- `--reseal-min-period` Can be used to control how often a new pending block is generated if `none` is not selected on prior option.
-- `--work-queue-size` Controls how many pending blocks to keep in memory.
-- `--relay-set`  Can be used to enable more strict transaction verification.
-- `--remove-solved` Move solved blocks from the work package queue instead of cloning them. This gives a slightly faster import speed, but means that extra solutions submitted for the same work package will go unused.
-- `--notify-work` Accepts a list of URLs that will receive a POST request when new work package is available. The body of the POST message is JSON encoded and has the same format as `eth_getWork` RPC response.
-
-##### RPC
-
-`eth_getWork` RPC response additionally includes the block number.
-
-##### DAO soft-fork
-
-DAO soft-fork control options have been replaced by the single `--fork` option which disables the soft-fork by default.
-
-#### Changes
-
-- v1.2.1 in beta [#1492](https://github.com/paritytech/parity/pull/1492)
-- (BETA) add artifacts [#1420](https://github.com/paritytech/parity/pull/1420)

-## Parity [v1.2.0: "Security"](https://github.com/paritytech/parity/releases/tag/v1.2.0) (2016-06-24)
-
-[Blog post](https://blog.parity.io/announcing-parity-1-2/)
-
-#### New
-
-- Transaction signing UI.
-- IPC/RPC module.
-- Optimised mining support.
-- Windows build.
-- DAO soft-fork support.
-
-##### Transaction signing UI
-
-This is a new framework for signing transactions. It fulfills three requirements:
-- You should never have to type your passwords into a Dapp.
-- No Javascript code should ever hold a secret.
-- No transaction should ever be signed without the consent of the user.
-
-The feature is enabled through the `--signer` flag. When enabled, the user must ensure at least one "Signer UI" is set-up for managing transaction confirmation. There are two such UIs available; one through a Google Chrome Extension, separately installable and the second through a special web page hosted locally. Set-up must be done once for each such UI, through copying and pasting a token from the output console of Parity into the UI. Specific instructions are given in the UI.
-
-From this point on, no transaction may ever be signed by Parity except through one of these allowed Signer UIs, and no password should ever be entered anywhere else.
-
-##### IPC/RPC module and Mist/Geth compatibility
-
-Should be started with `--geth` to ensure Mist compatibility.
-
-##### Optimised mining support
-
-Numerous improvements and optimisations have been added to our mining implementation. A large "active queue" ensures that late-included transactions are included in the mined block without sacrificing older results from latent-reported `ethminer` results.
-
-##### Windows build
-
-We're happy to announce full Windows support with 1.2!
-
-##### Soft-fork
-
-This release includes support for the proposed [DAO soft-fork](https://docs.google.com/document/d/10RktunzjKNfp6Y8Cu4EhR5V9IqxEZq42LU126EYhWY4/pub). Upon upgrade, all mining nodes can vote for or against the soft fork (this is done through altering the block gas limit; a gas limit of at most 4M results in the soft-fork being triggered).
-
-By default, nodes vote "for" the DAO soft-fork (and try to reduce the gas limit to 3.1M). To vote against the soft-fork (keeping it at 4.7M), run with `--dont-help-rescue-dao`. Not upgrading is not recommended; if the majority votes with a soft-fork, an upgrade will be necessary to mine on the correct chain.
-
-#### Changed
-- Fast pruning method is now default for a fresh sync.
-- Web UI renamed to Dapps UI.
-- JSONRPC and Dapps UI enabled by default.
-- CLI options ending `-off` renamed to GNU-consistent prefix `--no-`.
-- Dynamic gas-pricing (data feed and statistical techniques used to determine optimum gas prices).

-## Parity [v1.3.8](https://github.com/paritytech/parity/releases/tag/v1.3.8) (2016-10-15)
-
-Parity 1.3.8 is our EIP150 hard-fork compliant release.
-
-Running this will enact a mild change of the protocol at block number 2,463,000 which should occur on Tuesday 18th October 2016 at approximately 12:20 London time (BST). This change alters the gas prices for a number of operations, mainly centring around i/o intensive Merkle trie lookups (`BALANCE`, `EXTCODESIZE` &c.) and state-trie polluters (`SUICIDE`, `CREATE` and `CALL`). These operations were heavily underpriced, an oversight which lead to the recent degradation of network service. The full details of the alteration are specified in [EIP-150](https://github.com/ethereum/EIPs/issues/150).
-
-Additionally several issues have been fixed including:
-- a transaction queue limitation leading to dropped transactions;
-- a synchronisation issue leading to stalls when syncing;
-
-And some small features including database performance improvements and additional logging.
-
-#### Upgrading private chain specification files.
-
-All the chain specification files now have EIP-150 rules enabled by default. To continue using the chain add the `eip150Transition` key under `Engine/ethash/params` and set it to a future transition block as shown in [this example](https://github.com/paritytech/parity/blob/85eeb3ea6e5e21ad8e5644241edf82eb8069f536/ethcore/res/ethereum/morden.json#L13).
-
-The key related to homestead transition has been renamed from `frontierCompatibilityModeLimit` to `homesteadTransition`.

-
-## Parity [v1.3.4](https://github.com/paritytech/parity/releases/tag/v1.3.4) (2016-10-07)
-
-Parity 1.3.4 release contains more optimizations to internal caching as well as stability improvements.
-
-It also introduces an ability for miners to choose a transaction ordering strategy:
-
-    --tx-queue-strategy S    Prioritization strategy used to order transactions
-                             in the queue. S may be:
-                             gas - Prioritize txs with low gas limit;
-                             gas_price - Prioritize txs with high gas price;
-                             gas_factor - Prioritize txs using gas price
-                             and gas limit ratio [default: gas_factor].

-## Parity [v1.3.0: "Acuity"](https://github.com/paritytech/parity/releases/tag/v1.3.0) (2016-08-12)
-
-As well as many bug fixes, 1.3.0 includes a number of important improvements including:
-- **Optimisations** Heavily optimised block/transaction processing core - up to 2x faster than 1.2 series.
-- **Database compression** Databases take as much as 30% less storage than before.
-- **State snapshotting** An installation synchronised from scratch in 1-2 minutes can be made after downloading the 140MB state snapshot. See [the wiki](https://github.com/paritytech/parity/wiki/Getting-Synced) for more information.
-- **Process isolation** The networking/chain-synchronisation is now a fully independent process.
-
-Incremental improvements include:
-- Additional [RPCs](https://github.com/paritytech/parity/wiki/JSONRPC) for transaction tracing, state diffing, VM tracing, asynchronous transaction posting, accounts metadata and message signing.
-- Improved logging, including for chain reorganisations.
-- Added a `--fast-and-loose` option for additional speed-ups which can compromise integrity on a dirty shutdown.
-- Column families to ensure maximal inter-database integrity.
-- Key naming includes date/time of creation.
-- Various improvements to networking robustness and performance.
-- Solidity compilation supported through RPC if `solc` is available.
-- Various improvements to the miner including [HTTP push work notification](https://github.com/ethcoreparitytech/parity/wiki/Mining#starting-it).

-### Parity [v1.7.11](https://github.com/paritytech/parity/releases/tag/v1.7.11) (2017-12-29)
-
-Parity 1.7.11 changes the default behavior of JSON-RPC CORS setting, and updates bootnodes for the Kovan and Foundation networks.
-
-Note: The default value of `--jsonrpc-cors` option has been altered to disallow (potentially malicious) websites from accessing the low-sensitivity RPCs (viewing exposed accounts, proposing transactions for signing). Currently domains need to be whitelisted manually. To bring back previous behaviour run with `--jsonrpc-cors all` or `--jsonrpc-cors http://example.com`.

-### Parity [v1.7.10](https://github.com/paritytech/parity/releases/tag/v1.7.10) (2017-12-11)
-
-Parity 1.7.10 applies fixes for Proof-of-Authority networks and schedules the Kovan-Byzantium hard-fork.
-
-- The Kovan testnet will fork on block `5067000` at `Thu Dec 14 2017 05:40:03 UTC`.
-  - This enables Byzantium features on Kovan.
-  - This disables uncles on Kovan for stability reasons.
-- Proof-of-Authority networks are advised to set `maximumUncleCount` to 0 in a future `maximumUncleCountTransition` for stability reasons. See the [Kovan chain spec](https://github.com/paritytech/parity/blob/master/ethcore/res/ethereum/kovan.json) for an example. New PoA networks created with Parity will have this feature enabled by default.

-## Parity [v1.7.0](https://github.com/paritytech/parity/releases/tag/v1.7.0) (2017-07-28)
-
-Parity 1.7.0 is a major release introducing several important features:
-
-- **Experimental [Light client](https://github.com/paritytech/parity/wiki/The-Parity-Light-Protocol-(PIP)) support**. Start Parity with `--light` to enable light mode. Please, note: The wallet UI integration for the light client is not included, yet.
-- **Experimental web wallet**. A hosted version of Parity that keeps the keys and signs transactions using your browser storage. Try it at https://wallet.parity.io or run your own with `--public-node`.
-- **WASM contract support**. Private networks can run contracts compiled into WASM bytecode. _More information and documentation to follow_.
-- **DApps and RPC server merge**. DApp and RPC are now available through a single API endpoint. DApp server related settings are deprecated.
-- **Export accounts from the wallet**. Backing up your keys can now simply be managed through the wallet interface.
-- **PoA/Kovan validator set contract**. The PoA network validator-set management via smart contract is now supported by warp and, in the near future, light sync.
-- **PubSub API**. https://github.com/paritytech/parity/wiki/JSONRPC-Parity-Pub-Sub-module
-- **Signer apps for IOS and Android**.

-## Parity [v1.8.6](https://github.com/paritytech/parity/releases/tag/v1.8.6) (2018-01-10)
-
-Parity 1.8.6 fixes a critical issue with the database eventually filling up user's disks. Upgrading is highly recommended as it will significantly improve your user experience. As a bonus, this release should enable users with slower hard-disk drives to catch up with the latest block again. Also, warp-sync performance was significantly improved. Please note, that the initial database compaction after upgrading might temporarily reduce the node's performance.
-
-In addition to our gas price histogram, this version now allows you to dynamically set the default gas price as percentile from the last 100 blocks (it defaults to median: `50`).
-
-    --gas-price-percentile=[PCT]        Set PCT percentile gas price value from
-                                        last 100 blocks as default gas price
-                                        when sending transactions.
-
-Last but not least, this release also fixes consensus issues with the Expanse chain enabling Byzantium. If you run Parity configured for Expanse, you might have to resync your chain after the upgrade.

-## Parity [v1.8.5](https://github.com/paritytech/parity/releases/tag/v1.8.5) (2017-12-29)
-
-Parity 1.8.5 changes the default behavior of JSON-RPC CORS setting, detects same-key engine signers in Aura networks, and updates bootnodes for the Kovan and Foundation networks.
-
-Note: The default value of `--jsonrpc-cors` option has been altered to disallow (potentially malicious) websites from accessing the low-sensitivity RPCs (viewing exposed accounts, proposing transactions for signing). Currently domains need to be whitelisted manually. To bring back previous behaviour run with `--jsonrpc-cors all` or `--jsonrpc-cors http://example.com`.

-## Parity [v1.8.4](https://github.com/paritytech/parity/releases/tag/v1.8.4) (2017-12-12)
-
-Parity 1.8.4 applies fixes for Proof-of-Authority networks and schedules the Kovan-Byzantium hard-fork.
-
-- The Kovan testnet will fork on block `5067000` at `Thu Dec 14 2017 05:40:03 UTC`.
-  - This enables Byzantium features on Kovan.
-  - This disables uncles on Kovan for stability reasons.
-- Proof-of-Authority networks are advised to set `maximumUncleCount` to 0 in a future `maximumUncleCountTransition` for stability reasons.
-  - See the [Kovan chain spec](https://github.com/paritytech/parity/blob/master/ethcore/res/ethereum/kovan.json) for an example.
-  - New PoA networks created with Parity will have this feature enabled by default.
-
-Furthermore, this release includes the ECIP-1039 Monetary policy rounding specification for Ethereum Classic, reduces the maximum Ethash-block timestamp drift to 15 seconds, and fixes various bugs for WASM and the RPC APIs.

-## Parity [v1.8.1](https://github.com/paritytech/parity/releases/tag/v1.8.1) (2017-10-20)
-
-Parity 1.8.1 fixes several bugs with token balances, tweaks snapshot-sync, improves the performance of nodes with huge amounts of accounts and changes the Trezor account derivation path.
-
-**Important Note**: The **Trezor** account derivation path was changed in this release ([#6815](https://github.com/paritytech/parity/pull/6815)) to always use the first account (`m/44'/60'/0'/0/0` instead of `m/44'/60'/0'/0`). This way we enable compatibility with other Ethereum wallets supporting Trezor hardware-wallets. However, **action is required** before upgrading, if you have funds on your Parity Trezor wallet. If you already upgraded to 1.8.1, please downgrade to 1.8.0 first to recover the funds with the following steps:
-
-1. Make sure you have 1.8.0-beta and your Trezor plugged in.
-2. Create a new standard Parity account. Make sure you have backups of the recovery phrase and don't forget the password.
-3. Move your funds from the Trezor hardware-wallet account to the freshly generated Parity account.
-4. Upgrade to 1.8.1-beta and plug in your Trezor.
-5. Move your funds from your Parity account to the new Trezor account.
-6. Keep using Parity as normal.
-
-If you don't want to downgrade or move your funds off your Trezor-device, you can also use the official Trezor application or other wallets allowing to select the derivation path to access the funds.

-- Added support for Ellaism chain ([#7222](https://github.com/paritytech/parity/pull/7222)).
-
-Further, users upgrading from 1.8 should acknowledge the following changes:
-
-- Fixed DELEGATECALL's from/to field ([#7568](https://github.com/paritytech/parity/pull/7568)).
-- Set zero nonce and gas price for calls by default ([#6954](https://github.com/paritytech/parity/pull/6954)).
-- Create pending blocks with all transactions from the queue ([#6942](https://github.com/paritytech/parity/pull/6942)).
-- Remove RPC parameter leniency now that Mist formats correctly ([#6651](https://github.com/paritytech/parity/pull/6651)). Parity stops accepting decimal-formatted block numbers and stops parsing the empty string as empty bytes.
-- Public nodes do not support the user interface anymore. If you are running a public node, please stay on the 1.8 branch of the stable releases.
-
-Additional noteworthy changes:
-
-- `ethstore` and `ethkey` have been significantly improved ([#6961](https://github.com/paritytech/parity/pull/6961)):
-  - `ethstore` now supports brute forcing pre-sale wallets given a password list for recovery.
-  - `ethkey` now supports multi-threaded generation of prefix-matching addresses.
-  - `ethkey` now supports prefix-matching brain wallets.
-  - `ethkey` now supports brain-wallets recovery-phrases lookup. This helps to find a correct phrase if you know the address you want to get yet you made a typo backing the phrase up, or forgot a word.

-//! Light client logic and implementation.
-//!
-//! A "light" client stores very little chain-related data locally
-//! unlike a full node, which stores all blocks, headers, receipts, and more.
-//!
-//! This enables the client to have a much lower resource footprint in
-//! exchange for the cost of having to ask the network for state data
-//! while responding to queries. This makes a light client unsuitable for
-//! low-latency applications, but perfectly suitable for simple everyday
-//! use-cases like sending transactions from a personal account.
-//!
-//! The light client performs a header-only sync, doing verification and pruning
-//! historical blocks. Upon pruning, batches of 2048 blocks have a number => (hash, TD)
-//! mapping sealed into "canonical hash tries" which can later be used to verify
-//! historical block queries from peers.
