 FEATURES:
 
+* Travis test integration has been added. Now any file that is added as `<name>_test.vim` will be automatically tested in for every Pull Request (just like how we add tests to Go with `_test.go`). Going forward this will tremendously increase the stability and decrease the maintaince burden of vim-go. [gh-1157]
 * Add new `g:go_updatetime` setting to change the default updatetime (which was hardcoded previously) [gh-1055]
 * Add new `g:go_template_use_pkg` setting to enable to use cwd as package name instead of basic template file [gh-1124]
