Aave v3.7 Changelog

Core Contracts

Pool

  • Removed dropReserve(). Reserve removal is no longer supported at the pool level. See drop-reserve-removal.md.
  • Removed priceOracleSentinel from execution parameters (ExecuteLiquidationCallParams, ExecuteBorrowParams). See sentinel-removal.md.
  • Removed resetIsolationModeTotalDebt(). The isolationModeTotalDebt field in ReserveData is deprecated and returns 0 in view functions. See mode-removal.md.
  • liquidationCall no longer updates isolation mode debt counters. See mode-removal.md.
  • Added configureEModeCategoryIsolated(uint8 id, bool isolated) and getIsEModeCategoryIsolated(uint8 id) for the new isolated eMode feature. See isolated-emode.md.
  • PoolInstance: POOL_REVISION bumped from 10 to 11.

PoolConfigurator

  • Removed dropReserve(). See drop-reserve-removal.md.
  • Removed setDebtCeiling(), setSiloedBorrowing(), and setBorrowableInIsolation() — isolation mode and siloed borrowing have been removed. See mode-removal.md.
  • Removed getConfiguratorLogic() — ConfiguratorLogic is now an internal library, no longer deployed separately.
  • setEModeCategory now takes an additional bool isolated parameter. Added setEModeCategoryIsolated(uint8 categoryId, bool isolated) for updating the flag independently.
  • Config engine libraries are now inlined (no longer use delegatecall).
  • PoolConfiguratorInstance: CONFIGURATOR_REVISION bumped from 7 to 8.

LiquidationLogic

  • Deterministic rounding: percentMul/percentDiv calls in _calculateAvailableCollateralToLiquidate now use explicit rounding direction (percentMulFloor, percentDivFloor, percentMulCeil, percentDivCeil). The close-factor computation in executeLiquidationCall still uses the half-up percentMul.
  • Improved hasNoCollateralLeft detection: The check now uses scaled balance consumption (matching the actual rayDivCeil rounding of burn/transfer operations) instead of comparing base-currency values. This prevents stranded debt when ceil rounding depletes a position or when a few-wei leftover rounds to $0 in base currency. See liquidation-rounding.md.
  • Removed the 4th return value (collateralToLiquidateInBaseCurrency) from _calculateAvailableCollateralToLiquidate.
  • Removed isolation mode debt ceiling updates from the liquidation flow.
  • Added borrowerScaledCollateralBalance to LiquidationCallLocalVars (single SLOAD, reused for the scaled consumption check).

ValidationLogic

  • Removed MINIMUM_HEALTH_FACTOR_LIQUIDATION_THRESHOLD (sentinel-related). See sentinel-removal.md.
  • Removed priceOracleSentinel parameter from validateLiquidationCall and validateBorrow. See sentinel-removal.md.
  • Removed validateAutomaticUseAsCollateral. Simplified validateUseAsCollateral to no longer require reservesList parameter.
  • Removed validateDropReserve.
  • Removed siloed borrowing validation checks from validateBorrow.

Periphery

AaveV3ConfigEngine

  • Config engine libraries (BorrowEngine, CapsEngine, CollateralEngine, EModeEngine, ListingEngine, PriceFeedEngine, RateEngine) are now internal libraries called directly instead of via delegatecall. Removed EngineLibraries struct and per-engine address getters from IAaveV3ConfigEngine.
  • Removed isolation mode and siloed borrowing parameters: borrowableInIsolation, withSiloedBorrowing from Listing/BorrowUpdate; debtCeiling from Listing/CollateralUpdate.
  • Added isolated field to EModeCategoryUpdate and EModeCategoryCreation.

LiquidationDataProvider

  • Aligned rounding with LiquidationLogic: percentMulFloor, percentDivFloor, percentMulCeil in the same positions as the core contract.
  • debtBalanceInBaseCurrency now uses MathUtils.mulDivCeil (matching LiquidationLogic).
  • debtLeftoverInBaseCurrency in _adjustAmountsForGoodLeftovers now uses MathUtils.mulDivCeil (matching the dust check in LiquidationLogic).
  • Removed sentinel-related logic from _canLiquidateThisHealthFactor.

UiPoolDataProviderV3

  • isSiloedBorrowing and debtCeiling / debtCeilingDecimals fields are now hardcoded to false / 0 for backward compatibility (dynamic lookups removed).
  • Added isolated field to eMode category data.

UiIncentiveDataProviderV3

  • Fixed bug: vToken incentive user data was incorrectly using aTokenIncentiveController instead of vTokenIncentiveController.

AaveProtocolDataProvider

  • getDebtCeiling, getSiloedBorrowing now return hardcoded defaults (0 / false) for backward compatibility
  • getDebtCeilingDecimals returns 2 for backward compatibility.

Libraries

  • IsolationModeLogic: Deleted entirely. Isolation mode debt ceiling tracking is removed.
  • BorrowLogic: Removed isolation mode debt ceiling updates from executeBorrow and executeRepay.
  • SupplyLogic: Callers updated from validateAutomaticUseAsCollateral to validateUseAsCollateral. Removed reservesList parameter from supply/transfer validation paths.
  • PoolLogic: Removed executeDropReserve and executeResetIsolationModeTotalDebt.
  • FlashLoanLogic: Removed priceOracleSentinel from borrow params construction.
  • GenericLogic: Added @dev legacy comment on reserveAddress != address(0) checks explaining they guard against gaps left by the removed dropReserve feature.
  • ReserveConfiguration: Removed getDebtCeiling, setDebtCeiling, DEBT_CEILING_MASK, DEBT_CEILING_DECIMALS, MAX_VALID_DEBT_CEILING. Removed getSiloedBorrowing, setSiloedBorrowing, SILOED_BORROWING_MASK. Removed getBorrowableInIsolation, setBorrowableInIsolation, BORROWABLE_IN_ISOLATION_MASK.
  • UserConfiguration: Removed getIsolationModeState, getSiloedBorrowingState.
  • PercentageMath: Added percentDivFloor function (percentMulFloor, percentMulCeil, percentDivCeil already existed).
  • DataTypes: Deprecated debtCeiling bits in ReserveConfigurationMap (getter/setter removed, bits marked DEPRECATED). Removed priceOracleSentinel from ExecuteLiquidationCallParams, ExecuteBorrowParams, ValidateBorrowParams, and ValidateLiquidationCallParams. Added borrowerScaledCollateralBalance to LiquidationCallLocalVars. Added isolated flag to EModeCategory.
  • ConfiguratorLogic: Functions changed from external to internal (library is no longer deployed separately).
  • Errors: Removed DebtCeilingExceeded, UnderlyingClaimableRightsNotZero, VariableDebtSupplyNotZero, PriceOracleSentinelCheckFailed, AssetNotBorrowableInIsolation, InvalidDebtCeiling, DebtCeilingNotZero, SiloedBorrowingViolation. Renamed UserInIsolationModeOrLtvZero → UserHasAssetWithZeroLtv. Added MustNotLeaveDust.

Interfaces

  • IPriceOracleSentinel: Deleted.
  • ISequencerOracle: Deleted.
  • IPool: Removed dropReserve, resetIsolationModeTotalDebt, IsolationModeTotalDebtUpdated event. Added configureEModeCategoryIsolated, getIsEModeCategoryIsolated.
  • IPoolConfigurator: Removed dropReserve, setDebtCeiling, setSiloedBorrowing, setBorrowableInIsolation, getConfiguratorLogic. Removed events ReserveDropped, DebtCeilingChanged, SiloedBorrowingChanged, BorrowableInIsolationChanged. Removed dead event BridgeProtocolFeeUpdated (was never emitted). setEModeCategory now takes an additional bool isolated parameter. Added setEModeCategoryIsolated and EModeCategoryIsolationChanged event.
  • IPoolDataProvider: getDebtCeiling, getDebtCeilingDecimals, getSiloedBorrowing deprecated via NatSpec (kept for backward compatibility, return hardcoded defaults).
  • IDefaultInterestRateStrategyV2: NatSpec fixes (missing @notice prefixes, description correction).

Mocks

  • MockPoolInherited: Removed dropReserve override.
  • SequencerOracle: Deleted.
