Web3-klaytn

-----------------

Released Mar 27, 2018

*This is intended to be the final release before the stable v4 release.*

- Add support for geth 1.8 (fixed error on :meth:`~web3.eth.Eth.getTransactionReceipt`)
- You can now call a contract method at a specific block
with the ``block_identifier`` keyword argument, see:
:meth:`~web3.contract.ContractFunction.call`
- In preparation for stable release, disable ``w3.eth.account`` by default,
until a third-party audit is complete & resolved.
- New API for contract deployment, which enables gas estimation, local signing, etc.
See :meth:`~web3.contract.Contract.constructor`.
- Find contract events with :ref:`contract.events.$my_event.createFilter() <contract_createFilter>`
- Support auto-complete for contract methods.
- Upgrade most dependencies to stable

- eth-abi
- eth-utils
- hexbytes
- *not included: eth-tester and eth-account*
- Switch the default EthereumTesterProvider backend from eth-testrpc to eth-tester:
:class:`web3.providers.eth_tester.EthereumTesterProvider`
- A lot of documentation improvements
- Test node integrations over a variety of providers
- geth 1.8 test suite

-----------------

A little hiccup on release. Skipped.

-----------------

Released Feb 28, 2018

- New methods to modify or replace pending transactions
- A compatibility option for connecting to ``geth --dev`` -- see :ref:`geth-poa`
- A new :attr:`web3.net.chainId`
- Create a filter object from an existing filter ID.
- eth-utils v1.0.1 (stable) compatibility

-----------------

Released Feb 21, 2018

- bugfix: Compatibility with eth-utils v1-beta2
(the incompatibility was causing fresh web3.py installs to fail)
- bugfix: crash when sending the output of ``contract.functions.myFunction().buildTransaction()``
to :meth:`~web3.eth.Eth.sendTransaction`. Now, having a chainID key does not crash
sendTransaction.
- bugfix: a TypeError when estimating gas like:
``contract.functions.myFunction().estimateGas()`` is fixed
- Added parity integration tests to the continuous integration suite!
- Some py3 and docs cleanup

-------------

dependency conflicts between eth-utils, eth-abi, and eth-tester
- Clearer error message when invalid keywords provided to contract constructor function
- New docs for working with private keys + set up doctests

- replace internal implementation of w3.eth.account with
:class:`eth_account.account.Account`

Released Feb 7, 2018, then recalled. It added 32MB of test data to git history,
so the tag was deleted, as well as the corresponding release.
(Although the release would not have contained that test data)
