 1. The `npm` token can only be defined in the environment as `NPM_TOKEN`, because that’s where `npm` itself is going to read it from.

 For a special purpose tool like `semantic-release`, that's only meant to be used in controlled CI environments, we think it's okay to have such a high version requirement. As `semantic-release` handles package publishing we expect almost every project to have at least one build job running node 8 already – and that's all it takes. Even if that's not that case `semantic-release` can still be executed with the help of [npx](https://www.npmjs.com/package/npx) (`npx -p node@8 npm run semantic-release`).

+## Node Support Policy
+
+We only support [Long-Term Support](https://github.com/nodejs/Release) versions of Node starting with [Node 8.9.0 (LTS)](https://nodejs.org/en/blog/release/v8.9.0/).
+
+We specifically limit our support to LTS versions of Node, not because this package won't work on other versions, but because we have a limited amount of time, and supporting LTS offers the greatest return on that investment.
+
+It's possible this package will work correctly on newer versions of Node. It may even be possible to use this package on older versions of Node, though that's more unlikely as we'll make every effort to take advantage of features available in the oldest LTS version we support.
+
+As each Node LTS version reaches its end-of-life we will remove that version from the node engines property of our package's package.json file. Removing a Node version is considered a breaking change and will entail the publishing of a new major version of this package. We will not accept any requests to support an end-of-life version of Node. Any merge requests or issues supporting an end-of-life version of Node will be closed.
+
+We will accept code that allows this package to run on newer, non-LTS, versions of Node. Furthermore, we will attempt to ensure our own changes work on the latest version of Node. To help in that commitment, our continuous integration setup runs against all LTS versions of Node in addition the most recent Node release; called current.
+
+JavaScript package managers should allow you to install this package with any version of Node, with, at most, a warning if your version of Node does not fall within the range specified by our node engines property. If you encounter issues installing this package, please report the issue to your package manager.

Pierre Vanduynslager	8d575654c2	feat: make semantic-release CI agnostic - Remove `@semantic-release/condition-travis` from the default plugins - Verify the current branch in the core - Verify the build is not triggered by a PR in the core - Run in dry-run mode if not triggered on CI - Dry-run mode runs the `verifyConditions` plugins, allowing to detect configuration error locally - Return without error when no version has to be released due to no changes - Return without error if the build is triggered from a PR - Return without error if the current branch is not the configured branch - CLI return with exit code 1 if there is a `semanticReleaseError`, allowing to fail builds in case of config error, missing token etc... BREAKING CHANGE: `semantic-release` doesn't make sure it runs only on one Travis job anymore. The CI configuration has to be done such that `semantic-release` - runs only once per build - runs only after all tests are successful on every jobs of the build - runs on Node >=8 This can easily be done with [travis-deploy-once](https://github.com/semantic-release/travis-deploy-once). Migration Guide Modify your `.travis.yml` to use `travis-deploy-once`. Replace: ```yaml after_success: - npm run semantic-release ``` by: Replace ```yaml after_success: - npm install -g travis-deploy-once@4 - travis-deploy-once "npm run semantic-release" ```	2017-12-30 23:15:25 -05:00

Pierre Vanduynslager	754b420fd6	feat: support sharable configuration Adds the options `extends`, which can be defined via configuration file or CLI arguments to a single path or an array of paths of shareable configuration. A shareable configuration is a file or a module that can be loaded with `require`. Options is defined by merging in the following order of priority: - CLI/API - Configuration file - Shareable configuration (from right to left) Options set in a shareable configuration can be unset by setting it to `null` or `undefined` in the main configuration file. If a default value applies to this property it will be used.	2017-12-22 14:22:30 -05:00

Hutson BettsandGregor Martynus	0113db2e06	docs(README): add node support policy Add a _Node Support Policy_ section to the project's `README.md` file to indicate what this project, and its core team, are promising in terms of Node runtime support. Establishing a support policy provides reassurance to the community that they can expect a level of functionality from `semantic-release`, while providing guidance to the core maintainers, and everyone else that contributes, the level of support they should espire to.
