 ### Added
 
-- Implement `EnumerableSet::values_slice` to prevent out-of-gas scenarios when querying large sets by returning paginated results. #827
+- **UUPS Proxy**: `UUPSUpgradeable` contract and `IErc1822Proxiable` trait for user-controlled upgradeable proxies.
+- **Beacon Proxy**: `BeaconProxy` contract and `IBeacon` interface, supporting the beacon proxy pattern for upgradeable contracts.
+- **Upgradeable Beacon**: `UpgradeableBeacon` contract, allowing upgradeable beacon-based proxies with owner-controlled implementation upgrades.
+- **Enumerable Sets**: Generic `EnumerableSet` type with implementations for `Address`, `B256`, `U8`, `U16`, `U32`, `U64`, `U128`, `U256`.
+- **Token Receivers**: `IErc1155Receiver` and `IErc721Receiver` traits with corresponding `Erc1155Holder` and `Erc721Holder` contracts.
+- **Access Control Extensions**: `AccessControlEnumerable` extension that supports role member enumeration.
+- **Enhanced SafeERC20**: Additional methods including `try_safe_transfer`, `try_safe_transfer_from`, and relaxed call variants.
+- **Cryptography**: EDDSA (Ed25519) signature scheme, Twisted-Edwards Curves, and enhanced elliptic curve configurations (secp256k1, Baby Jubjub, Bandersnatch, Curve25519, Jubjub).
+- **Precompiles**: Enhanced `Precompiles` trait with `p256_verify` wrapper function for ergonomic precompile invocation.
+- **Type Conversions**: Bidirectional conversions between `ruint::Uint` and crypto library `Uint` types, plus conversions between `Uint` and primitive integer types.
 
-### Changed (Breaking)
+### Changed
 
-- Updated the `UUPSUpgradeable` logic for determining where the call originated. #810
-- Prefix `ct_` removed for constant functions at  `openzeppelin-crypto`. #846
+- **Type Aliases**: Standardized `FixedBytes<4>` to `B32`, `FixedBytes<32>` to `B256`, and `StorageFixedBytes<32>` to `StorageB256`.
+- **API Simplifications**: Simplified Pedersen hash API to accept any type implementing `Into<P::BaseField>`.
+- **Interface Compliance**: Removed redundant interface ID checks in `Erc1155Supply`.
 
-### Fixed
+### Changed (Breaking)
 
-- Proper Bandersnatch and Jubjub elliptic curves parameters. #809
-- `AdminChanged` event parameters no longer indexed. #794
-- Fix `ruint::Uint` padding for conversion to `Uint`. #808
-- Improved panic description for twisted edwards point conversions. #816
-- Fix edge case with U64 -> u128 conversion. #815
-- Conditional compilation in storage slot utilities causing build failures across different target architectures and feature combinations. #823
-- Add code check and use high-level calls in `SafeErc20::*_relaxed` calls to handle boolean decoding. #837
-- Add code check and use high-level calls in `SafeErc20::allowance` to handle U256 decoding. #833
-- Prevent ECDSA signature malleability in `P256VERIFY` precompile by rejecting high-s values. #825
-- Fixed zeroization for eddsa `ExpandedSecretKey` and `SigningKey`. #831
-- Add constant `HAS_MODULUS_SPARE_BIT` to `PrimeField`. #835
-- Add constant `Uint::from_uint(..)` function. `Fp::from_fp(..)` is now constant also. #834
-- Fixed incorrect transformation for Projective Points with Zero z-coordinate. #817
+- **Interface Naming**: Renamed Solidity interfaces for consistency (`IERC721Receiver` → `IErc721ReceiverInterface`, `IERC1155Receiver` → `IErc1155ReceiverInterface`).
+- **Trait Bounds**: Added `IErc721Receiver` trait bound to `IErc721Wrapper` trait.
+- **Error Handling**: Replaced associated error types with raw byte output (`Vec<u8>`) in receiver traits for ABI compliance.
+- **Deref Removal**: Removed `Deref` implementations for extension contracts to improve API clarity.
+- **API Simplifications**: Prefix `ct_` removed for constant functions at  `openzeppelin-crypto`.
