CHANGELOG.md

@@ -4,6 +4,7 @@
 
 ### Unreleased
 
+- Allow configuration of the output directory of the generated `BuildInfo` [#1433](https://github.com/gakonst/ethers-rs/pull/1433)
 - capture unknown fields in `Block` and `Transaction` type via new `OtherFields` type [#1423](https://github.com/gakonst/ethers-rs/pull/1423)
 - Methods like `set_to()` from `TypedTransaction` can be chained
 - Use H64 for Block Nonce [#1396](https://github.com/gakonst/ethers-rs/pull/1396)
