 ## Changelog: eth-gas-reporter
 
+0.2.0 / 2019-05-07
+==================
+  * Add E2E tests in CI
+  * Restore logic that matches tx signatures to contracts as a fallback when it's impossible to
+    be certain which contract was called (contribution @ItsNickBarry)
+  * Fix bug which crashed reporter when migrations linked un-deployed contracts
+

 ### Usage Notes
-+ Requires Node >= 8.
-+ Method calls that throw are filtered from the stats.
-+ Contracts that are only ever created by other contracts within Solidity are not shown in the deployments table.

 ### Contributions
-Please feel free to open a PR (or an issue) for anything. The units are an integration test and one of them is expected to fail, verifying that the table prints at the end of a suite even when there are errors. If you're adding an option, you can vaildate it in CI by adding it to the mock options config located [here](https://github.com/cgewecke/eth-gas-reporter/blob/master/mock/config-template.js#L13-L19).

 All the ideas in this utility have been borrowed from elsewhere. Many thanks to:
-+ [@maurelian](https://github.com/maurelian) - Mocha reporting gas instead of time is his idea.
-+ [@cag](https://github.com/cag) - The table borrows from / is based his gas statistics work for the Gnosis contracts.
-+ [Neufund](https://github.com/Neufund/ico-contracts) - Block limit size ratios for contract deployments and euro pricing are borrowed from their `ico-contracts` test suite.
