Please issue pull request against the
3.x-dev branch only.
Piwik 2 is in LTS mode. This means we do not accept any pull request for 2.x except critical security bugs and major data loss bugs.
If you need to create a pull request for 2.x, then please also create the pull request against the
3.x-dev so we can merge both.
Thanks for your PR. Unfortunatelly we can't merge PRs for translation files. Our translations are managed using transifex. Please get an account there in order to help us improving the translations.
