version: mark 2.2.0 beta (#9820)

* version: mark 2.2.0 beta

* ci: remove failing tests for android, windows, and macos (#9788)

* ci: remove failing tests for android, windows, and macos

* ci: restore android build jobs

* Move state root verification before gas used (#9841)

* Classic.json Bootnode Update (#9828)

* fix: Update bootnodes list to only responsive nodes

* feat: Add more bootnodes to classic.json list

* feat: Add retested bootnodes

* Implement NoProof for json tests and update tests reference (replaces #9744) (#9814)

* Update test reference.
Block test are really not working so I disabled a few by commenting
directly in source.

* Move ethtest commit cursor.

* Implements 'NoProof' engine from https://github.com/ethereum/tests/issues/464 .

Since tests has been regenerated those one were failing on block
difficulty check.

Update ethereum/tests, waiting for cost fix (block test are still
commented).

* Update tests submodule reference to latest (all test passing except an
identified case).
Fix block reward of constantinople json.

* Restore broken test by using old json tests files.

* Use CanonNoSeal instead of a custom engine, still have to include some
additional tests code.

* Gas upper limit check in json_chain test was bad, moving the test to
verification, the test is running in `verify_header_param`.
Note that test was previously only for ethash, and now for any engine.

* Restore old behavior (gas uper limit only for ethash engine), at the
cost of an additional trait method.

* Proper rpc test fix.

* Update tests submodule, add SStore bug tests.

* Fix json issue tabulation.
Update tests submodule to latest master (lot of new sstore tests
passing)

* Switch ethereum/tests to tag 6.0.0-beta.1 (no tests changes from latest
synch).

* Display hex with separator, use indirection instead of clone for copy
types.

+## Technical Overview
 
-Official website: https://parity.io | Be sure to check out [our wiki](https://wiki.parity.io) for more information.
+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.

-Parity's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity using the sophisticated and cutting-edge Rust programming language. Parity is licensed under the GPLv3, and can be used for all your Ethereum needs.
+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.
 
-From Parity Ethereum client version 1.10.0, the User Interface (UI) is accessible in a separate application called Parity UI. To keep using the UI in the browser (deprecated), [follow these steps](https://wiki.parity.io/FAQ-Basic-Operations,-Configuration,-and-Synchronization#the-parity-ui-application-isnt-working-the-way-i-want).
+## Build Dependencies
 
-By default, Parity will also run a JSONRPC server on `127.0.0.1:8545` and a websockets server on `127.0.0.1:8546`. This is fully configurable and supports a number of APIs.
+Parity Ethereum requires **Rust version 1.29.x** to build.

+
+The full list of included changes:

+  - Parity-version: bump stable to 1.11.9
+  - Fix compilation error on nightly rust ([#8707](https://github.com/paritytech/parity-ethereum/pull/8707))
+    - On nightly rust passing `public_url` works but that breaks on stable. This works for both.
+  - Parity-version: bump stable to 1.11.10
+  - Check if synced when using eth_getWork ([#9193](https://github.com/paritytech/parity-ethereum/issues/9193)) ([#9210](https://github.com/paritytech/parity-ethereum/pull/9210))
+    - Check if synced when using eth_getWork ([#9193](https://github.com/paritytech/parity-ethereum/issues/9193))
+    - Don't use fn syncing
+    - Fix identation
+    - Fix typo
+    - Don't check for warping
+    - Rpc: avoid calling queue_info twice on eth_getWork
+  - Fix potential as_usize overflow when casting from U256 in miner ([#9221](https://github.com/paritytech/parity-ethereum/pull/9221))
+  - Allow old blocks from peers with lower difficulty ([#9226](https://github.com/paritytech/parity-ethereum/pull/9226))
+    - Previously we only allow downloading of old blocks if the peer difficulty was greater than our syncing difficulty. This change allows downloading of blocks from peers where the difficulty is greater then the last downloaded old block.
+  - Update Dockerfile ([#9242](https://github.com/paritytech/parity-ethereum/pull/9242))
+    - Update Dockerfile
+    - Fix Docker build
+  - Fix dockerfile paths: parity -> parity-ethereum ([#9248](https://github.com/paritytech/parity-ethereum/pull/9248))
+  - Update tobalaba.json ([#9313](https://github.com/paritytech/parity-ethereum/pull/9313))
+  - Light client `Provide default nonce in transactions when it´s missing` ([#9370](https://github.com/paritytech/parity-ethereum/pull/9370))
+    - Provide `default_nonce` in tx`s when it´s missing
+    - When `nonce` is missing in a `EthTransaction` will cause it to fall in these cases provide `default_nonce` value instead!
+  - Changed http:// to https:// on Yasm link ([#9369](https://github.com/paritytech/parity-ethereum/pull/9369))
+    - Changed http:// to https:// on Yasm link in README.md
+    - Provide `default_nonce` in tx`s when it´s missing
+    - When `nonce` is missing in a `EthTransaction` will cause it to fall in these cases provide `default_nonce` value instead!
+    - Address grumbles
+  - Ethcore: kovan: delay activation of strict score validation ([#9406](https://github.com/paritytech/parity-ethereum/pull/9406))
+  - Use impl Future in the light client RPC helpers ([#8628](https://github.com/paritytech/parity-ethereum/pull/8628))
+  - Better support for eth_getLogs in light mode ([#9186](https://github.com/paritytech/parity-ethereum/pull/9186))
+    - Light client on-demand request for headers range.
+    - Cache headers in HeaderWithAncestors response.
+      - Also fulfills request locally if all headers are in cache.
+    - Lightfetch::logs fetches missing headers on demand.
+    - Lightfetch::logs limit the number of headers requested at a time.
+    - Lightfetch::logs refactor header fetching logic.
+    - Enforce limit on header range length in light client logs request.
+    - Fix light request tests after struct change.
+    - Respond to review comments.
+  - Propagate transactions for next 4 blocks. ([#9265](https://github.com/paritytech/parity-ethereum/pull/9265))
+    - This PR also removes the limit of max 64 transactions per packet, currently we only attempt to prevent the packet size to go over 8MB. This will only be the case for super-large transactions or high-block-gas-limit chains.
+    - Patching this is important only for chains that have blocks that can fit more than 4k transactions (over 86M block gas limit)
+    - For mainnet, we should actually see a tiny bit faster propagation since instead of computing 4k pending set, we only need `4 * 8M / 21k = 1523` transactions.
+  - Ethcore: fix pow difficulty validation ([#9328](https://github.com/paritytech/parity-ethereum/pull/9328))
+    - Ethcore: fix pow difficulty validation

+    - Ethcore: add issue link to regression test
+    - Ethcore: fix tests
+    - Ethcore: move difficulty_to_boundary to ethash crate

+## Parity-Ethereum [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.
+
+The full list of included changes:

+## Parity-Ethereum [v2.0.3](https://github.com/paritytech/parity-ethereum/releases/tag/v2.0.3) (2018-09-01)
+
+Parity-Ethereum 2.0.3-beta is a bug-fix release to improve performance and stability. Hopefully. ;)
+
+The full list of included changes:

+    - Don't use fn syncing
+    - Fix identation
+    - Fix typo
+    - Don't check for warping

+    - Fix potential as_usize overflow when casting from U256 in miner ([#9221](https://github.com/paritytech/parity-ethereum/pull/9221))
+    - Allow old blocks from peers with lower difficulty ([#9226](https://github.com/paritytech/parity-ethereum/pull/9226))
+    - Previously we only allow downloading of old blocks if the peer difficulty was greater than our syncing difficulty. This change allows downloading of blocks from peers where the difficulty is greater then the last downloaded old block.

+    - Closes [#9255](https://github.com/paritytech/parity-ethereum/issues/9255)
+    - This PR also removes the limit of max 64 transactions per packet, currently we only attempt to prevent the packet size to go over 8MB. This will only be the case for super-large transactions or high-block-gas-limit chains.
+    - Patching this is important only for chains that have blocks that can fit more than 4k transactions (over 86M block gas limit)
+    - For mainnet, we should actually see a tiny bit faster propagation since instead of computing 4k pending set, we only need `4 * 8M / 21k = 1523` transactions.
+  - Update tobalaba.json ([#9313](https://github.com/paritytech/parity-ethereum/pull/9313))

+## 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`.
