0.7.0

What's Changed

Enhancements

• Add combined event filters: fetch multiple events (OR semantics) in a single eth_getLogs
  request with Ethers.EventFilter.combine/1, or all events of a contract by passing its
  EventFilters module (e.g. Ethers.get_logs(MyContract.EventFilters, address: "0x...")) —
  the resulting Ethers.CombinedEventFilter works with Ethers.get_logs/2 and
  Ethers.batch/2 and decodes each fetched log with its matching event selector
• Add EIP-191 personal message support: hash, recover
  and verify messages with Ethers.PersonalMessage, and sign them via Ethers.personal_sign/2
  with the Ethers.Signer.Local and Ethers.Signer.JsonRPC signers through the new optional
  personal_sign/2 signer callback (named after the RPC method it mirrors)
• Add universal signature verification with Ethers.Signature: verify any signature —
  EOA (ecrecover), smart-contract wallets (ERC-1271)
  and counterfactual, not-yet-deployed wallets (ERC-6492)
  against a digest, an EIP-191 personal message or EIP-712 typed data with
  Ethers.Signature.verify_hash/4, verify_message/4 and verify_typed_data/4
• Add Sign-In with Ethereum (EIP-4361) support with
  Ethers.Siwe: build (new/1), render (to_message/1), parse (parse/1) and validate
  (validate/2) SIWE messages, generate session nonces (generate_nonce/0), and verify a
  message and its signature end-to-end with Ethers.Siwe.verify/3 — smart-contract wallets
  included via the universal signature verification above
• Add EIP-712 typed data support: construct typed
  structured data with Ethers.TypedData, hash it (encode_type, type_hash, hash_struct,
  domain_separator, hash), sign it via Ethers.sign_typed_data/2 with the Ethers.Signer.Local
  and Ethers.Signer.JsonRPC (eth_signTypedData_v4) signers, and recover/verify the signer with
  Ethers.TypedData.recover_signer/2 and Ethers.TypedData.valid_signature?/3
• Add a struct DSL for EIP-712 typed data: declare typed-data struct types as Elixir modules with
  use Ethers.TypedData.Schema and the typed_schema/field macros, then build an
  Ethers.TypedData directly from struct instances via Ethers.TypedData.new/2 (and new!/2)
