+# 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 1.7.3 enables the Byzantium fork for Ethereum main network on Block 4_370_000 and offers a variety of bug fixes and stability improvements. Among them:
+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.
 
-- Fixed network protocol version negotiation with Geth nodes v1.7.1+.
-- Fixed `RETURNDATA` size for built-ins. (Built-ins in some cases overwrite only a portion of the output memory slice.)
-- Multisig Wallet View now loads if multiple transactions happened within one block.
-- Improved stability of snapshot-sycns (warp).
-- Revised timeout and batch size constants for bigger blocks.
-- Renamed RPC receipt `statusCode` field to `status`.
+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 [v1.7.2](https://github.com/paritytech/parity/releases/tag/v1.7.2) (2017-09-18)
+## Parity [v1.8.4](https://github.com/paritytech/parity/releases/tag/v1.8.4) (2017-12-12)
 
-Parity 1.7.2 is a bug-fix release to improve performance and stability. Among others, it addresses the following:
+Parity 1.8.4 applies fixes for Proof-of-Authority networks and schedules the Kovan-Byzantium hard-fork.
 
-- Byzantium fork support for the Ropsten and Foundation networks.
-- Added support for the ConsenSys and Gnosis multi-signature wallets.
-- Significantly increased token registry and token balance lookup performance.
-- Fixed issues with the health status indicator in the wallet.
-- Tweaked warp-sync to quickly catch up with chains fallen back more than 10,000 blocks.
-- Fixes to the Chrome extension and macOS installer upgrades.
+- 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.
 
-Full list of included changes:
+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 1.7.0 is a major release introducing several important features:
+## Parity [v1.8.3](https://github.com/paritytech/parity/releases/tag/v1.8.3) (2017-11-15)
 
-- **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 1.8.3 contains several bug-fixes and removes the ability to deploy built-in multi-signature wallets.

+
+## 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.
+

+### 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`.
+
+The full list of included changes:
+
+- Stable Bootnodes and Warpnodes ([#7298](https://github.com/paritytech/parity/pull/7298))
+  - New warp enodes ([#7287](https://github.com/paritytech/parity/pull/7287))
+    - New warp enodes

+### 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.
