6.12.0

@vvo I had to open a PR for updating the CHANGELOG and package.json. Otherwise locally, I get the following error:

remote: error: GH006: Protected branch update failed for refs/heads/master.
remote: error: Required status check "continuous-integration/travis-ci" is expected. At least one approved review is required by reviewers with write access.
To github.com:vvo/selenium-standalone.git
 ! [remote rejected] master -> master (protected branch hook declined)
error: failed to push some refs to 'git@github.com:vvo/selenium-standalone.git'

Since the npm run release command does modify files locally, you may need to modify protected branch settings.

I'll release these changes once the travis checks finish.

Removed protected branch untill there's a better release way (via PRs)
