The full list of included changes:

Stable backports for 1.11.10 (#9228)
- Parity-version: bump stable to 1.11.9
- Fix compilation error on nightly rust (#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) (#9210)
  - Check if synced when using eth_getWork (#9193)

  - 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)
- Allow old blocks from peers with lower difficulty (#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)
  - Update Dockerfile
  - Fix Docker build
- Fix dockerfile paths: parity -> parity-ethereum (#9248)
- Update tobalaba.json (#9313)
- Light client Provide default nonce in transactions when it´s missing (#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)
  - 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)
- Use impl Future in the light client RPC helpers (#8628)
- Better support for eth_getLogs in light mode (#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)
  - 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
  - Ethcore: validate difficulty is not zero

Parity-Ethereum 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 (2018-05-15)

This is the Parity 1.11.1-beta release! Hurray!

Notable changes in reversed alphabetical order:

TOOLING: Whisper CLI #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
- 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
- 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
- Parity now provides a private transactions system.
- Please, check out our wiki to get an overview and setup instructions.
CORE: New Transaction Queue implementation #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 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
- 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
- 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.
CONFIGURATION: Auto-updater improvements #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
- This activates the Ellaism Byzantium hardfork (2018-0004-byzantium) at block 2_000_000.
- This enables the Wasm VM on Ellaism (2018-0003-wasm-hardfork) 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
- 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
- This activates the Musicoin Byzantium hardfork (MCIP-6) at block 2_222_222.
- Please, upgrade your clients if you run a Musicoin configuration.
