# CHANGELOG
+## v0.3.0 - _TBD, 2018_
+
+ * Add coverage subprovider if SOLIDITY_COVERAGE env variable is true (#426)
+ * Refactor `BlockchainLifecycle` to work with in-process ganache (#426)
+ * Remove `RPC` class and move it's logic to `Web3Wrapper` (#426)
+
## v0.2.0 - _February 16, 2018_
* Remove subproviders (#392)

Dev utils to be shared across 0x projects and packages
+## Configuration
+
+Some env variables might be set to change the behaviour of created web3 providers/instances.
+
+```
+VERBOSE_GANACHE: boolean. Enables verbose Ganache logging. Every request/response payload. Slightly slower, but useful for testing.
+SOLIDITY_COVERAGE: boolean. If set - adds coverage subprovider which intercepts all calls/transactions and can be later used to compute code coverage.
+```
+
+Boolean env variables should be either `true` or `false`. Defaults to `false` if not set.
+
## Install
