+## Changes
 
 ### Added
-- [*BREAKING*] `implementation`, `override` macros: [78](https://github.com/Brushfam/openbrush-contracts/pull/78) 
-- [*BREAKING*] `storage_item` macro, new OB feature: `Upgradeable`, which implements `set_code_hash` functionality [99](https://github.com/Brushfam/openbrush-contracts/pull/99)
-- `UI` tests [77](https://github.com/Brushfam/openbrush-contracts/pull/77)
-- `openbrush::accessors` macro for automatic generation of getters/setters for storage items: [66](https://github.com/Brushfam/openbrush-contracts/pull/66) and [61](https://github.com/Brushfam/openbrush-contracts/pull/61)
+- [*BREAKING*] `implementation`, `override`, `default_impl` macros: [#78](https://github.com/Brushfam/openbrush-contracts/pull/78) 
+- [*BREAKING*] `storage_item` macro, which implements `#[ink::storage_item]` macro, but also allows to make field of struct upgradeable by using `#[lazy]` attribute. For all fields that
+ are either `Lazy`/`Mapping`/`MultiMapping` is generated it's own constant storage key. Also it allows OpenBrush to work correctly with every default implementation [#99](https://github.com/Brushfam/openbrush-contracts/pull/99)
+- New OB feature: `Upgradeable`, which implements `set_code_hash` functionality [#99](https://github.com/Brushfam/openbrush-contracts/pull/99)
+- `UI` tests for testing different scenarios for macros [#77](https://github.com/Brushfam/openbrush-contracts/pull/77)
+- `openbrush::accessors` macro for automatic generation of getters/setters for storage items: [#66](https://github.com/Brushfam/openbrush-contracts/pull/66) and [61](https://github.com/Brushfam/openbrush-contracts/pull/61)
 
 ### Removed
-- [*BREAKING*] `min_specilization`, now openbrush is `stable`: [78](https://github.com/Brushfam/openbrush-contracts/pull/78)
-- `ZERO_ADDRESS`, now using `Option<AccountId>` instead: [98](https://github.com/Brushfam/openbrush-contracts/pull/98)
+- [*BREAKING*] `upgradeable_storage` macro, `OccupyStorage` trait [#99](https://github.com/Brushfam/openbrush-contracts/pull/99)
+- [*BREAKING*] `min_specilization`, now OpenBrush can be used with `stable` toolchain: [#78](https://github.com/Brushfam/openbrush-contracts/pull/78)
+- [*BREAKING*] `ZERO_ADDRESS`, now using `Option<AccountId>` instead: [#98](https://github.com/Brushfam/openbrush-contracts/pull/98)
+
+### Changed
+
+- [*BREAKING*] Now every field in OpenBrush's types that is not read/written directly in storage, is wrapped in `Lazy`, so all the types in OpenBrush can be considered upgradeable: [#99](https://github.com/Brushfam/openbrush-contracts/pull/99)
 
 ### Fixed
 - Fixed reentrancy guard problem: [#88](https://github.com/Brushfam/openbrush-contracts/pull/88)
+- Updated reentrancy example: [#108](https://github.com/Brushfam/openbrush-contracts/pull/108)
