 ## [Git master](https://github.com/cucumber/cucumber-jvm/compare/v1.1.1...master)
 
+* [Core] Strip command line arguments in case people accidentally invoke `cucumber.api.cli.Main` with arguments that have spaces left and right. (Aslak Hellesøy)
 * [Core] Implemented `DataTable.equals()` and `DataTable.hashCode()`. (Aslak Hellesøy)
 * [Core] Support `DataTable.toTable(List<String[]>) and `DataTable.toTable(List<Map<String,String>>)` ([#433](https://github.com/cucumber/cucumber-jvm/issues/433), [#434](https://github.com/cucumber/cucumber-jvm/pull/434) Nicholas Albion, Aslak Hellesøy)
 * [Core] Formatters and `--dotcucumber` can now write to a file or an URL (via HTTP PUT). This allows easier distribution of reports. (Aslak Hellesøy)
