CHANGELOG
## v4.1.2 - _December 11, 2018_
* Dependencies updated
## v4.1.1 - _November 28, 2018_
* Dependencies updated
## v4.1.0 - _November 21, 2018_
* Add a `nonce` field for `TxOpts` so that it's now possible to re-broadcast stuck transactions with a higher gas amount (#1292)
## v4.0.2 - _November 14, 2018_
* Dependencies updated
## v4.0.1 - _November 13, 2018_
* Dependencies updated
## v4.0.0 - _November 12, 2018_
* Add signature validation, regular cancellation and `cancelledUpTo` checks to `validateOrderFillableOrThrowAsync` (#1235)
* Improved the errors thrown by `validateOrderFillableOrThrowAsync` by making them more descriptive (#1235)
* Throw previously swallowed network errors when calling `validateOrderFillableOrThrowAsync` (see issue: #1218) (#1235)
## 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
* Updated to use new modularized artifacts. (#1105)
* Top-level `ContractWrappers` class has a new optional `contractAddresses` parameter. (#1105)
* Default contract addresses are no longer stored in artifacts and are instead loaded from the `@0xproject/contract-addresses` package. (#1105)
* Most contract addresses are now defined at instantiation time and are available as properties (e.g., `exchangeWrapper.address`) instead of methods (e.g., `exchangeWrapper.getContractAddress()`). (#1105)
* 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)
