+# ShellExec CHANGELOG
+
+## Unreleased
+
+
+
+## 1.0.0
+
+- Initial release
+  - Simpler API than Exec (`command` string vs. `commandLine` list)
+  - Append/prepend to `PATH`
+  - Supports command pipes and conditional command chains
+  - Easy access to `stdout`/`stderr`
+  
+⚠️ Not compatible with `Exec` tasks yet (#11), but the current API is very similar.
+
+## 0.1.0
+
+- Test release
+- Original name: [SimpleExec](https://bintray.com/phatblat/maven-open-source/SimpleExec)
