v1.0.0

Summary

openzeppelin_access

Added

• Add missing event emissions on state changes (#159)
• two_step_transfer::request_borrow_val and request_return_val for borrowing the wrapper and its inner object during a pending transfer.
• two_step_transfer::RequestBorrow hot potato to guarantee wrapper return after request_borrow_val.

Changed (Breaking)

• Redesigned two_step_transfer from a requester-initiated to an owner-initiated flow using shared PendingOwnershipTransfer and TTO.
  • request, transfer, and reject replaced by initiate_transfer, accept_transfer, and cancel_transfer.
• Renamed two_step_transfer events: OwnershipRequested → TransferInitiated, OwnershipTransferred → TransferAccepted, OwnershipTransferRejected → TransferCancelled.
• All events in two_step_transfer and delayed_transfer now carry phantom T for type-specific indexing.
• two_step_transfer::unwrap now accepts an additional &mut TxContext param (#159)
• delayed_transfer::wrap now takes an explicit recipient and transfers the wrapper to that address instead of returning DelayedTransferWrapper<T>.
• delayed_transfer::schedule_transfer and schedule_unwrap now derive current_owner from ctx.sender() instead of accepting it as a parameter (#174)
• Emit dedicated UnwrapExecuted event on delayed_transfer::unwrap instead of OwnershipTransferred (#168)

openzeppelin_math

Fixed

• Preserve the remainder for u512::div_rem_u256 even when the quotient overflows, preventing incorrect results in mul_mod for large operands (#151)

v1.0.0-rc.0

Summary

openzeppelin_math

Added

• rounding::RoundingMode enum plus helpers for expressing Down/Up/Nearest behavior reused across all arithmetic APIs.
• public u8, u16, u32, u64, u128, and u256 modules exposing averaged computations, checked shifting, configurable mul_div and mul_shr, logarithms, square roots, and modular math helpers tailored to each bit width.
• u512 wide integer type that supports splitting, multiplication, and division helpers to safely handle 512-bit intermediates needed by the narrow modules.
• coin_utils helpers that upcast or downcast balances between decimal domains (up to 24 decimals) with overflow checks and explicit truncation semantics.

openzeppelin_access

Added

• two_step_transfer module that wraps a key + store capability behind a request/approve flow.
• delayed_transfer module that enforces configurable, clock-based delays before transferring or unwrapping a capability.
