You can now map dist-tags onto "fallbackTags". E.g. if you want a
development channel like "next" and no version is currently published as "next"
semantic-release will fallback to "latest" to determine the new "next" version.
This is now the default for "next" -> "latest", but you can specify your own
mappings by adding "fallbackTags" to your `package.json`'s "release" field.
BREAKING CHANGE: In cases where you pushed a new commit with a "dist-tag"
configuration of "next" and no version was previously published as "next",
semanitc-release failed and did not publish a new version. It will now
automatically fall back to to "latest".

`semantic-release` builds upon a set of conventions to give you **fully automated, semver-compliant package publishing**. It's mostly about _commit-messages_, but you can define more_heuristics_.
Out of the box this is just about _commit-messages_, but you can do so much more.

This removes the immediate connection between human emotions and version numbers, so strictly following the [SemVer](http://semver.org/) spec is not a problem anymore – and that’s ultimately `semantic-release`’s goal.

## How does it work?
Instead of writing [meaningless commit messages](http://whatthecommit.com/), we can take our time to think about the changes in the codebase and write them down. Following formalized conventions it this then possible to generate a helpful changelog and to derive the next semantic version number from them.
_Note: This module ships with the [AngularJS Commit Message Conventions](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit) and changelog generator, but you can [define your own](#plugins) style_.

format that includes a **type**, a **scope** and a **subject**:
When `semantic-release` got setup it will do that after every successful continuous integration build of your master branch (or any other branch you specify) and publish the new version for you. That way no human is directly involved in the release process and your releases are guaranteed to be [unromantic and unsentimental](http://sentimentalversioning.org/).
If you fear the loss of control over timing and marketing implications of software releases you should know that `semantic-release` supports [release channels](https://github.com/npm/npm/issues/2718) using `npm`'s [dist-tags](https://docs.npmjs.com/cli/tag). This way you can keep control over what your users end up using by default, you can decide when to promote an automatically released version to the stable channel and you can choose which versions to write blogposts and tweets about. You can use the same mechanism to support older versions of your software, for example with important security fixes.

While this entirely true the version number doesn't have to be checked into source control. `semantic-release` takes care of the version field right before `npm publish` uses it – and this is the only point where it _really_ is required.

### Can I run this on my own machine rather than on a CI server?
Of course you can, but this doesn't necessarily mean you should. Running your tests on an independent machine before releasing software is a crucial part of this workflow. Also it is a pain to set this up locally, with tokens lying around and everything. That said, you can run the scripts with `--debug=false` explicitly. You have to export `GH_TOKEN=<your_token>` and `NPM_TOKEN=<your_other_token>`.

### Is it _really_ a good idea to release on every push?
It is indeed a great idea because it _forces_ you to follow best practices. If you don't feel comfortable making every passing feature or fix on your master branch addressable via `npm` you might not treat your master right. Have a look at [branch workflows](https://guides.github.com/introduction/flow/index.html). If you still think you should have control over the exact point in time of your release, e.g. because you are following a release schedule, you can release only on the `production`/`deploy`/`release` branch and push your code there in certain intervals, or better yet use [dist-tags](https://docs.npmjs.com/cli/dist-tag).

### Why should I trust `semantic-release` with my releases?
`semantic-release` has a full unit- and integration-test-suite that tests _actual_`npm` publishes against the [npm-registry-couchapp](https://github.com/npm/npm-registry-couchapp/) on node.js `^0.10`, `^0.12` and io.js `^1`, `^2`. A new version won't get published if it doesn't pass on all these engines.
