## v0.34.0 - _April 2, 2018_
* Fix the bug causing `zeroEx.exchange.fillOrdersUpToAsync` validation to fail if there were some extra orders passed (#470)
* Removed `ZeroExError.TransactionMiningTimeout` and moved it to '@0xproject/web3_wrapper' `Web3WrapperErrors.TransactionMiningTimeout` (#485)
* Remove automatic instantiation of `zeroEx.orderStateWatcher` (#488)
* Add `zeroEx.createOrderStateWatcher` to allow creating arbitrary number of OrderStateWatchers (#488)
* Added `stateLayer` setting to `OrderStateWatcherConfig` so OrderStateWatcher can be set to monitor different blockchain state layers (#488)
