+### Features
+
+* Removed runtime git dependency. ([f1b3129](https://github.com/sbrow/envr/commit/f1b3129f7dc26d177cd9b5bb7b0807d9871a91c5))
+
+
+### Performance Improvements
+
+* Replaced `fd` with custom internals. ([2ef733f](https://github.com/sbrow/envr/commit/2ef733fe58594b0a0b6e3ef85142b74af445ccb8))
