Release Notes

ethereumjs/ethereumjs-monorepo (ethereumjs-util)

v7.1.5: ethereumjs-util v7.1.5

Compare Source

• More flexible signature module methods now allow for passing in v values of 0 and 1 in the context of typed txs (e.g. EIP-1559 txs): ecrecover(), toRpcSig(), toCompactSig(), isValidSignature(), PR #​1905

Buffer <-> Uint8Array Conversion Helpers (RLP v3)

The new RLP v3 release is accepting and returning Uint8Array objects instead of Buffer for improved browser compatibility and usage.

There are two new helper functions in the bytes module from the Util library introduced in PR #​1648 to help with associated Buffer conversions (while this is our main reason for introducing these functions the functionality can of course be used for other things as well):

• arrToBufArr(): Converts a Uint8Array or NestedUint8Array to Buffer or NestedBufferArray
• bufArrToArr(): Converts a Buffer or NestedBufferArray to Uint8Array or NestedUint8Array

Note: the RLP version exposed by this package as a re-export is still RLP v2. This won't change along additional v7 Util releases and other current monorepo libraries (VM, Tx,...) are also still using the v2 RLP version.

Features

• New validateNoLeadingZeroes() function in bytes module for validating Buffers to have no leading zeros (mainly within an RLP context), PR #​1568
• New MAX_UINT64 constant which can be used to check if a BN instance exceeds the max. possible 64-bit integer value, PR #​1568

Maintenance

• toBuffer (bytes module) now throws when a negative BN is provided as input, PR #​1606
• Dependencies: deduplicated RLP import, PR #​1549

v7.1.3: ethereumjs-util v7.1.3

Removal of ethjs-util Package Re-Export

This release replaces ethjs-util dependency with an internal.ts file which re-exports all the used functions (thanks to @​talentlessguy for the PR).

This has a list of benefits:

• Less maintenance burden (fewer dependencies to care about)
• Better types and avoids use of deprecated APIs (e.g. new Buffer)
• Smaller bundle/install size

See: PR #​1517

Related Changes / Bug Fixes

• Fixed a bug in toUtf8 not working correctly with leading or trailing single 0s, see PR #​1522
• Rewrote toUtf8 function and added extended code docs, method now throws on malformed uneven hex input values, see PR #​1525

v7.1.2: ethereumjs-util 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: ethereumjs-util 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
