 # CHANGELOG
 
+## v0.32.2 - _February 9, 2018_
+
+    * Fix publishing issue where .npmignore was not properly excluding undesired content (#389)
+
+## v0.32.1 - _February 7, 2018_
+
+    * Reorganized `BlockParamLiteral` export into `@0xproject/types` package (#355)
+    * Now using `abi-gen` package to generate ContractEventArgs types (#371)
+
+## v0.32.0 - _February 5, 2018_
+
+    * Add `zeroEx.etherToken.getContractAddressIfExists` (#350)
+    * Fixed the bug causing order watcher to throw if there is an event with the same signature but different indexed fields (#366)
+
+## v0.31.1 - _February 1, 2018_
+
+    * Fix the bug causing order watcher to throw if makerToken === zrx (#357)
+
+## v0.31.0 - _January 30, 2018_
+
+    * Add the `shouldAddPersonalMessagePrefix` parameter to `signOrderHashAsync` so that the
+    caller can decide on whether to add the personalMessage prefix before relaying the request
+    to the signer. Parity Signer, Ledger and TestRPC add the prefix themselves, Metamask expects
+    it to have already been added. (#349)
+
+## v0.30.2 - _January 29, 2018_
+
+    * Add Rinkeby testnet addresses to artifacts  (#337)
+    * Move @0xproject/types to dependencies from devDependencies fixing missing type errors
+
+## v0.30.1 - _January 24, 2018_
+
+    * Fix a bug allowing negative fill values  (#212)
+    * Fix a bug that made it impossible to pass a custom ZRX address  (#341)
+
+## v0.30.0 - _January 17, 2018_
+
+    * Add an error parameter to the order watcher callback (#312)
+    * Fix a bug making it impossible to catch some errors from awaitTransactionMinedAsync (#312)
+    * Fix a bug in fillOrdersUpTo validation making it impossible to fill up to if user doesn't have enough balance to fully fill all the orders (#321)
+
 ## v0.29.1 - _January 11, 2018_
 
     * Fixed bignumber config issue #301 (#305)
