Parity-Ethereum 2.0.4-beta is a bug-fix release to improve performance and stability:
-`eth_coinbase` now provides an actual account for light clients
- don't report skipped primaries when empty steps are enabled in proof-of-authority networks
- fix snapshot restoration failure on windows
- check warp sync status for `eth_getWorks`
The full list of included changes:

- Parity-version: bump beta to 2.0.4
- [Light/jsonrpc] Provide the actual account for `eth_coinbase` RPC and unify error handeling for light and full client ([#9383](https://github.com/paritytech/parity-ethereum/pull/9383))
- Provide the actual `account` for eth_coinbase
- The previous implementation always provided the `zero address` on `eth_coinbase` RPC. Now, instead the actual address is returned on success or an error when no account(s) is found!
- Full client `eth_coinbase` return err
- In the full-client return an error when no account is found instead of returning the `zero address`
- Remove needless blocks on single import
- Remove needless `static` lifetime on const
- Fix `rpc_eth_author` test
- Parity: print correct keys path on startup ([#9501](https://github.com/paritytech/parity-ethereum/pull/9501))

Parity-Ethereum 2.0.3-beta is a bug-fix release to improve performance and stability. Hopefully. ;)
The full list of included changes:
- Beta backports for 2.0.3 ([#9229](https://github.com/paritytech/parity-ethereum/pull/9229))
- parity-version: bump beta to 2.0.2
- remove ssl from dockerfiles, closes [#8880](https://github.com/paritytech/parity-ethereum/issues/8880) ([#9195](https://github.com/paritytech/parity-ethereum/pull/9195))
- snap: remove ssl dependencies from snapcraft definition ([#9222](https://github.com/paritytech/parity-ethereum/pull/9222))

- Address grumbles
- Address grumbles
- Fix tests
- 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))

- 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.
- 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.
- Enforce limit on header range length in light client logs request.
- Fix light request tests after struct change.

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`.
