• #4807 f1ac4480d0c1c6f29bf709f116068e903643ecad Thanks @jxom! - viem/tempo: Supported calling token .call builders without a Client (restores the pre-2.54 call signature).

  -// ^? bigint

• #4767 0def05663277a93e645bc28740a78bfc916810ec Thanks @jxom! - Breaking: Changed ERC-20 token actions to resolve token symbols from the Client tokens array instead of built-in chain tokens config.

   import { createPublicClient, http } from 'viem'
   import { mainnet } from 'viem/chains'
  +import { usdc } from 'viem/tokens'
  
  -const client = createPublicClient({ chain: mainnet, transport: http() })
  +const client = createPublicClient({

  +  transport: http(),
  +})
  
   const balance = await client.token.getBalance({ account, token: 'usdc' })
