[Unreleased]

The entries below are relative to the zcash_client_backend crate as of zcash_client_backend 0.10.0.

Added

• The following modules have been extracted from zcash_client_backend and moved to this crate:
  • address
  • encoding
  • keys
• zcash_keys::address::UnifiedAddress::{unknown, has_orchard, has_sapling, has_transparent}:
• zcash_keys::keys:
  • AddressGenerationError
  • UnifiedAddressRequest
• A new orchard feature flag has been added to make it possible to build client code without orchard dependendencies.

Changed

• zcash_keys::address:

  • RecipientAddress has been renamed to Address
  • Address::Shielded has been renamed to Address::Sapling
  • UnifiedAddress::from_receivers no longer takes an Orchard receiver argument unless the orchard feature is enabled.
  • UnifiedAddress::orchard is now only available when the orchard feature is enabled.

• zcash_keys::keys:

  • DerivationError::Orchard is now only available when the orchard feature is enabled.
  • UnifiedSpendingKey::address now takes an argument that specifies the receivers to be generated in the resulting address. Also, it now returns Result<UnifiedAddress, AddressGenerationError> instead of Option<UnifiedAddress> so that we may better report to the user how address generation has failed.
  • UnifiedSpendingKey::orchard is now only available when the orchard feature is enabled.
  • UnifiedSpendingKey::transparent is now only available when the transparent-inputs feature is enabled.
  • UnifiedFullViewingKey::new no longer takes an Orchard full viewing key argument unless the orchard feature is enabled.

Removed

• zcash_keys::address::AddressMetadata has been moved to zcash_client_backend::data_api::TransparentAddressMetadata and fields changed.
