 ### Features
 - Added `env::random_seed_array` to return a fixed length array of the `random_seed` and optimizes the existing function. [PR 692](https://github.com/near/near-sdk-rs/pull/692)
+- Added event logs to `near-contract-standards`. Currently only NFT related events. [PR 627](https://github.com/near/near-sdk-rs/pull/627)
 
 ## `4.0.0-pre.5` [12-23-2021]
 - fix(standards): Fix NFT impl macros to not import `HashMap` and `near_sdk::json_types::U128`. [PR 571](https://github.com/near/near-sdk-rs/pull/571).
