 ### Triggering a release

-When pushing new commits to the release branch (i.e. `master`) with `git push` or by merging a pull request or merging from another branch, a CI build is triggered and runs the `semantic-release` command to make a release if there is relevant codebase changes since the last release.

 By default a release will be done for each push to the release branch that contains relevant code changes. If you need more control over the timing of releases you have a couple of options:
 - Publish releases on a distribution channel (for example npm’s [dist-tags](https://docs.npmjs.com/cli/dist-tag)). This way you can keep control over what your users end up using by default, and you can decide when to make an automatically released version available to the stable channel, and promote it.

-Plugins specific options can be set similarly to the other **semantic-release** [options](configuration.md#options) or within the plugin `Object`.
