this makes it easier to create npm scripts to handle releases, If I'm not mistaken, currently I would need 3 different config files or pass the version in the commit message (which I don't need to do). With this update I can create scripts like the following:

package.json

...
  "scripts": {
    "release:minor": "versionist --minor",
    "release:patch": "versionist --patch",
    "release:major": "versionist --major"
  },
...

Im also using the versionist-plugins to handle commiting, tagging, and pushing, but If I wasn't I could chain commands here

[danielmahon]

here is the corresponding config:

versionist.conf.js

const plugins = require('versionist-plugins');

module.exports = {
  updateVersion: [plugins.git.commit, plugins.git.tag, plugins.git.push],
  template: [
    '## v{{version}} - {{moment date "Y-MM-DD"}}',
    '',
    '{{#each commits}}',
    '- {{capitalize this.subject}}',
    '{{/each}}',
  ].join('\n'),
  getGitReferenceFromVersion: version => `v${version}`,
};

Thoughts on implementing this? Do I need to fix something?
