Major Changes

• 0d4b293: Changed return type of functions from a object with number indexes, to an array merged with object containing named
  outputs.

  Before, solidity function like this:

  function x() public pure returns (uint256)
  

  Generated such method signature:

  x(overrides?: CallOverrides): Promise<{0: BigNumber}>;
  

  New output is:

  x(overrides?: CallOverrides): Promise<[BigNumber]>;
  

  The difference is that now you can use standard array destructuring while working with output types.

Patch Changes

• db5baa5: Do not generate typings in contract type itself for reserved keywords that would collide with ethers internals

Major Changes

• f8711eb: Changed return type of functions from an array to a object. This represents better runtime types.

  Before, solidity function like this:

  function x() public pure returns (uint256)
  

  Generated such method signature:

  x(txDetails?: Truffle.TransactionDetails): Promise<[BigNumber]>;
  

  New output is:

  x(txDetails?: Truffle.TransactionDetails): Promise<{0: BigNumber}>;

@typechain/ethers-v4

Fix broken import paths in generated factories. https://github.com/ethereum-ts/TypeChain/issues/304

Changes:

• [Breaking] Rename TypeChain generated factories to from ${CONTRACT_NAME}Factory to ${CONTRACT_NAME}__factory Fixes: https://github.com/ethereum-ts/TypeChain/issues/225
• [Breaking] Move generated factories to /factories subdir. Fixes: https://github.com/ethereum-ts/TypeChain/issues/225

Changes:

• [Breaking] Rename TypeChain generated factories to from ${CONTRACT_NAME}Factory to ${CONTRACT_NAME}__factory Fixes: https://github.com/ethereum-ts/TypeChain/issues/225
• [Breaking] Move generated factories to /factories subdir. Note that index.ts still exposes all factories (with new names) Fixes: https://github.com/ethereum-ts/TypeChain/issues/225

TypeChain 4:

• Do not camel case contract names - BREAKING https://github.com/ethereum-ts/TypeChain/pull/293
• Support for unknown types (that couldn't be parsed or guessed) - BREAKING FOR TARGETS https://github.com/ethereum-ts/TypeChain/pull/291

All targets were bumped to a new major version to support the new unknown type

target-ethers-v5

• remove not needed dependency on ethers (only peer-dep is needed)

• BREAKING - bump ts-generator which results in a slightly different preamble for generated files and different formatting

target-ethers-v5

• export all types in index.ts https://github.com/ethereum-ts/TypeChain/issues/278

• Fix decoding of enums in libs
• Add --show-stack-traces CLI option for printout full stack trace on errors

• New target ethers-v5
• Better handling for overloads for ethers-v4

• Fix reliance on Web3 and BN instead of BigNumber.js [Truffle-v4]

• Add link method to contract constructor by @petejkim

• fix at typings for truffle v4/v5 by @petejkim

• Use raw names for artifacts.require BREAKING by @JamesLefrere
• Export contract types in artifact headers by @JamesLefrere

TypeChain Ver 2 is finally out! 🎉 🎉 🎉

Breaking changes:

• changed target naming schema. All officially supported targets are released as @typechain/X-vY Check out the readme for more details
• name mangling - we will change generated contract names to obey TypeScript naming rules
• Web3-v1
  • fixed bug in struct handling
  • type check payable calls
  • support for overloaded functions which can result in a slightly different code if you relied on using the first overload
• All targets:
  • support for overloaded functions which can result in a slightly different code if you relied on using the first overload
• Support events with no parameters names (API breaking change)
• We don't require truffle-typings package anymore - it's generated on the fly.

All changes

• Truffle-v5 support with events, function overloads etc
• NatSpec support by @chmanie
• Brand new testing pipeline which should help us ensure high quality of generated code

• [ethers] fix argument types for bytes & numbers by @quezak

• [ethers] named arguments for function args encoding methods by @quezak
