+    * `getAssetBuyerForProvidedOrders` factory function now takes 3 args instead of 4 (#1187)

+    * Fix bug where `BuyQuoteInfo` objects could return `totalEthAmount` and `feeEthAmount` that were not whole numbers (#1207)
+    * Fix bug where default values for `AssetBuyer` public facing methods could get overriden by `undefined` values (#1207)
+    * Lower default expiry buffer from 5 minutes to 2 minutes (#1217)

 CHANGELOG
 
+## v3.0.1 - _November 9, 2018_
+
+    * Fix bug in `ForwarderWrapper` where `feeRecipientAddress` was not correctly normalized. (#1178)
+
 ## v3.0.0 - _October 18, 2018_
 
     * Add optional validation to the forwarder wrapper methods
@@ -15,6 +19,8 @@ CHANGELOG
     * Removed `setProvider` method in top-level `ContractWrapper` class and added new `unsubscribeAll` method. (#1105)
     * Some properties and methods have been renamed. For example, some methods that previously could throw no longer can, and so their names have been updated accordingly. (#1105)
     * Removed ContractNotFound errors. Checking for this error was somewhat ineffecient. Relevant methods/functions now return the default error from web3-wrapper, which we feel provides enough information. (#1105)
+    * Add `ForwarderWrapperError` to public interface (#1147)
+    * Add `ContractWrapperError.SignatureRequestDenied` to public interface (#1147)
 
 ## v2.0.2 - _October 4, 2018_

+## 0x-order-utils
+
+0x order-related utilities for those developing on top of 0x protocol.
+
+Read the [documentation](https://0x.readthedocs.io/projects/order-utils/en/latest/)
+
+## Installing
+
+```bash
+pip install 0x-order-utils
+```
+
+## Contributing
+
+We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install Code and Dependencies
+
+Ensure that you have installed Python >=3.6 and Docker. Then:
+
+```bash
+pip install -e .[dev]
+```
+
+### Test
+
+Tests depend on a running ganache instance with the 0x contracts deployed in it. For convenience, a docker container is provided that has ganache-cli and a snapshot containing the necessary contracts. A shortcut is provided to run that docker container: `./setup.py ganache`. With that running, the tests can be run with `./setup.py test`.
+
+### Clean
+
+`./setup.py clean --all`
+
+### Lint
+
+`./setup.py lint`
+
+### Build Documentation
+
+`./setup.py build_sphinx`
+
+### More
+
+See `./setup.py --help-commands` for more info.
