[v6] Migration Notes: Things that changed

[corbanbrook]

Suggestion

While porting a library from ethers v5 -> v6 I came across functions which were renamed or function differently than their v5 counterparts. I thought I would make some notes in this ticket to get some clarification andto help others with their migration efforts.

Also As @ricmoo noted in https://github.com/ethers-io/ethers.js/issues/3725 "I’ve been using v6 forever now, so I’ve kinda lost track of what has changed." :) to help with migration docs.

v5 -> v6

• AddressZero -> ZeroAddress
• HashZero -> ZeroHash
• arrayify -> getBytes
• hexValue -> toQuantity
• hexDataSlice -> dataSlice
• hexZeroPad -> - zeroPadValue
• hexlify(value: BytesLike | Hexable | number | bigint) -> hexlify(value: BytesLike) No longer works on numbers
• solidityPack -> solidityPacked
• Web3Provider -> BrowserProvider
• splitSignature -> ???
• checkProperties -> ???
• shallowCopy -> ???

These are the surface level utils + constants ive noticed so far.

Thanks! I’ll add all these for the next patch release in a few hours. ;)

what is splitSignature updated to?

[ricmoo]

@quiet-node Signature.from(sig) where sig can be properties (like { r, s, v }) or a serialized hexdata.

The info is here. :)

@ricmoo thanks a lot! this is embarrassing I was literally on that Migrating from v5 page and couldn't find I was blind. Thanks much!
