Release Notes

ethereumjs/ethereumjs-monorepo

v7.1.2

Compare Source

• Replaced the ethjs-util intToHex and intToBuffer re-exports with own implementations which throw on wrong integer input (decimal values, non-safe integers, negative numbers,...) to allow for a safer integer type input, PR #​1500

v7.1.1

Compare Source

• Fixed a bug in toType() helper function to now return null/undefined for respective input values, PR #​1477
• Add note discouraging use of EIP-1191 format checksums when using toChecksumAddress() (breaks checksum backwards compatibility in current form), PR #​1463

v7.1.0

Distribution Changes

Dual ES5 and ES2017 Builds

We significantly updated our internal tool and CI setup along the work on PR #​913 with an update to ESLint from TSLint for code linting and formatting and the introduction of a new build setup.

Packages now target ES2017 for Node.js builds (the main entrypoint from package.json) and introduce a separate ES5 build distributed along using the browser directive as an entrypoint, see PR #​921. This will result in performance benefits for Node.js consumers, see here for a releated discussion.

Included Source Files

Source files from the src folder are now included in the distribution build, see PR #​1301. This allows for a better debugging experience in debug tools like Chrome DevTools by having working source map references to the original sources available for inspection.

EIP-2098 Support (Compact 64-byte Signatures)

The signature module comes with a new helper function toCompactSig(v: BNLike, r: Buffer, s: Buffer, chainId?: BNLike): string which allows to convert signature parameters into the format of Compact Signature Representation as defined in EIP-2098.

Other Changes

• Renamed bnToRlp()helper function to bnToUnpaddedBuffer(), PR #​1293

v7.0.10

Compare Source

• Added Address.isPrecompileOrSystemAddress() method which returns true if address is in the address range defined by EIP-1352, PR #​1170
• Return false (instead of throwing) for non-hex-string values in account module isValidAddress, isValidChecksumAddress, isZeroAddress methods (it now gets enough to just handle the false case on function usage), PR #​1173
