What's Changed

This release refines EVM-compatible address handling and introduces a clear migration path to the new SDK package. Developers targeting Hedera's EVM integration should take note of the new method for address translation and the associated deprecations.

Enhancements

• <EntityId>.toEvmAddress():
  Now available for AccountId, ContractId, ContractDelegateId, TopicId, TokenId, and FileId. This provides a standardized way to obtain EVM-compatible 20-byte addresses from Hedera entity IDs.
• <EntityId>.fromEvmAddress(shard, realm, evmAddress):
  Shard and realm are no longer encoded into the EVM address. They must be passed explicitly when constructing an EntityId from an EVM address.

Documentation

• Migration guide to @hiero/sdk v3:
  Includes comprehensive documentation, automated scripts for Unix and Windows, supported file types, and a template for migration-related issues.

Deprecations

• fromSolidityAddress() has been replaced with fromEvmAddress().
• toSolidityAddress() has been replaced with toEvmAddress().
• EthereumFlow has been deprecated. With the introduction of jumbo transactions, it is now more cost-effective and efficient to use EthereumTransaction.
