[Unreleased]

[0.3.0] - 2024-08-19

Notable changes

• zcash_keys:
  • Now supports TEX (transparent-source-only) addresses as specified in ZIP 320.
  • An unstable-frost feature has been added in order to be able to temporarily expose API features that are needed specifically when creating FROST threshold signatures. The features under this flag will be removed once key derivation for FROST has been fully specified and implemented.

Added

• zcash_keys::address::Address::try_from_zcash_address
• zcash_keys::address::Receiver
• zcash_keys::keys::UnifiedAddressRequest
  • intersect
  • to_address_request

Changed

• MSRV is now 1.70.0.
• Updated dependencies:
  • zcash_address-0.4
  • zcash_encoding-0.2.1
  • zcash_primitives-0.16
  • zcash_protocol-0.2
• zcash_keys::Address has a new variant Tex.
• zcash_keys::address::Address::has_receiver has been renamed to can_receive_as.
• zcash_keys::keys:
  • The (unstable) encoding of UnifiedSpendingKey has changed.
  • DerivationError::Transparent now contains bip32::Error.

[0.2.0] - 2024-03-25

Added

• zcash_keys::address::Address::has_receiver
• impl Display for zcash_keys::keys::AddressGenerationError
• impl std::error::Error for zcash_keys::keys::AddressGenerationError
• impl From<hdwallet::error::Error> for zcash_keys::keys::DerivationError when the transparent-inputs feature is enabled.
• zcash_keys::keys::DecodingError
• zcash_keys::keys::UnifiedFullViewingKey::{parse, to_unified_incoming_viewing_key}
• zcash_keys::keys::UnifiedIncomingViewingKey

Changed

• zcash_keys::keys::UnifiedFullViewingKey::{find_address, default_address} now return Result<(UnifiedAddress, DiversifierIndex), AddressGenerationError> (instead of Option<(UnifiedAddress, DiversifierIndex)> for find_address).
• zcash_keys::keys::AddressGenerationError
  • Added DiversifierSpaceExhausted variant.
• At least one of the orchard, sapling, or transparent-inputs features must be enabled for the keys module to be accessible.
• Updated to zcash_primitives-0.15.0

Removed

• UnifiedFullViewingKey::new has been placed behind the test-dependencies feature flag. UFVKs should only be produced by derivation from the USK, or parsed from their string representation.

Fixed

• UnifiedFullViewingKey::find_address can now find an address for a diversifier index outside the valid transparent range if you aren't requesting a transparent receiver.

[0.1.1] - 2024-03-04

Added

• zcash_keys::keys::UnifiedAddressRequest::all

Fixed

• A missing application of the sapling feature flag was remedied; prior to this fix it was not possible to use this crate without the sapling feature enabled.

[0.1.0] - 2024-03-01

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

Added

• zcash_keys::address (moved from zcash_client_backend::address). Further additions to this module:
  • UnifiedAddress::{has_orchard, has_sapling, has_transparent}
  • UnifiedAddress::receiver_types
  • UnifiedAddress::unknown
• zcash_keys::encoding (moved from zcash_client_backend::encoding).
• zcash_keys::keys (moved from zcash_client_backend::keys). Further additions to this module:
  • AddressGenerationError
  • UnifiedAddressRequest
• A new orchard feature flag has been added to make it possible to build client code without orchard dependendencies.
• zcash_keys::address::Address::to_zcash_address

Changed

• The following methods and enum variants have been placed behind an orchard feature flag:
  • zcash_keys::address::UnifiedAddress::orchard
  • zcash_keys::keys::DerivationError::Orchard
  • zcash_keys::keys::UnifiedSpendingKey::orchard
• 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.
• zcash_keys::keys:
  • 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::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 (use zcash_client_backend::data_api::TransparentAddressMetadata instead).
