for #2543
BREAKING CHANGE: semantic-release is now ESM-only. since it is used through its own executable, the impact on consuming projects should be minimal
BREAKING CHANGE: references to plugin files in configs need to include the file extension because of executing in an ESM context
- Allow to configure multiple branches to release from
- Allow to define a distribution channel associated with each branch
- Manage the availability on distribution channels based on git merges
- Support regular releases, maintenance releases and pre-releases
- Add the `addChannel` plugin step to make an existing release available on a different distribution channel
BREAKING CHANGE: the `branch` option has been removed in favor of `branches`
The new `branches` option expect either an Array or a single branch definition. To migrate your configuration:
- If you want to publish package from multiple branches, please the configuration documentation
- If you use the default configuration and want to publish only from `master`: nothing to change
- If you use the `branch` configuration and want to publish only from one branch: replace `branch` by `branches` (`"branch": "my-release-branch"` => `"branches": "my-release-branch"`)
- Allow to run semantic-release (via API) from anywhere passing the current working directory.
- Allows to simplify the tests and to run them in parallel in both the core and plugins.
- Remove the `getLastRelease` plugin type
- Retrieve the last release based on Git tags
- Create the next release Git tag before calling the `publish` plugins
BREAKING CHANGE: Remove the `getLastRelease` plugin type
The `getLastRelease` plugins will not be called anymore.
BREAKING CHANGE: Git repository authentication is now mandatory
The Git authentication is now mandatory and must be set via `GH_TOKEN`, `GITHUB_TOKEN`, `GL_TOKEN`, `GITLAB_TOKEN` or `GIT_CREDENTIALS` as described in [CI configuration](https://github.com/semantic-release/semantic-release/blob/caribou/docs/usage/ci-configuration.md#authentication).
- Add a new plugin type: `publish`
- Add support for multi-plugin. A plugin module can now return an object with a property for each plugin type
- Uses by default [npm](https://github.com/semantic-release/npm) and [github](https://github.com/semantic-release/github) in addition of Travis for the verify condition plugin
- Uses by default [npm](https://github.com/semantic-release/npm) and [github](https://github.com/semantic-release/github) for the publish plugin
- `gitTag` if one can be found is passed to `generateNotes` for both `lastRelease` and `nextRelease`
- `semantic-release` now verifies the plugin configuration (in the `release` property of `package.json`) and throws an error if it's invalid
- `semantic-release` now verifies each plugin output and will throw an error if a plugin returns an unexpected value.
BREAKING CHANGE: `githubToken`, `githubUrl` and `githubApiPathPrefix` have to be set at the [github](https://github.com/semantic-release/github) plugin level. They can be set via `GH_TOKEN`, `GH_URL` and `GH_PREFIX` environment variables.
BREAKING CHANGE: the `npm` parameter is not passed to any plugin anymore. Each plugin have to read `.npmrc` if they needs to (with https://github.com/kevva/npm-conf for example).
