Get a list of repository files and directories in a project. This endpoint can be accessed without authentication if the repository is publicly accessible. This command provides essentially the same features as the `git ls-tree` command. For more information, refer to the section [Tree Objects](https://git-scm.com/book/en/v2/Git-Internals-Git-Objects/#_tree_objects) in the Git internals documentation.

Enabled by default. Generate changelog data based on commits in a repository. Given a [semantic version](https://semver.org/) and a range of commits, GitLab generates a changelog for all commits that use a particular [Git trailer](https://git-scm.com/docs/git-interpret-trailers). GitLab adds a new Markdown-formatted section to a changelog file in the Git repository of the project. The output format can be customized. For user-facing documentation, see [Changelogs](../user/project/changelogs.md). ```plaintext POST /projects/:id/repository/changelog ``` ### Supported attributes Changelogs support these attributes: | Attribute | Type | Required | Description | | :-------- | :------- | :--------- | :---------- | | `version` | string | yes | The version to generate the changelog for. The format must follow [semantic versioning](https://semver.org/). | | `branch` | string | no | The branch to commit the changelog changes to. Defaults to the project's default branch. | | `config_file` | string | no | Path to the changelog configuration file in the project's Git repository. Defaults to `.gitlab/changelog_config.yml`. | | `date` | datetime | no | The date and time of the release. Defaults to the current time. | | `file` | string | no | The file to commit the changes to. Defaults to `CHANGELOG.md`. | | `from` | string | no | The SHA of the commit that marks the beginning of the range of commits to include in the changelog. This commit isn't included in the changelog. | | `message` | string | no | The commit message to use when committing the changes. Defaults to `Add changelog for version X`, where `X` is the value of the `version` argument. | | `to` | string | no | The SHA of the commit that marks the end of the range of commits to include in the changelog. This commit _is_ included in the changelog. Defaults to the branch specified in the `branch` attribute. Limited to 15000 commits unless the feature flag `changelog_commits_limitation` is disabled. | | `trailer` | string | no | The Git trailer to use for including commits. Defaults to `Changelog`. Case-sensitive: `Example` does not match `example` or `eXaMpLE`. | ### Requirements for `from` attribute If the `from` attribute is unspecified, GitLab uses the Git tag of the last stable version that came before the version specified in the `version` attribute. For GitLab to extract version numbers from tag names, Git tag names must follow a specific format. By default, GitLab considers tags using these formats: - `vX.Y.Z` - `X.Y.Z` Where `X.Y.Z` is a version that follows [semantic versioning](https://semver.org/). For example, consider a project with the following tags: - v1.0.0-pre1 - v1.0.0 - v1.1.0 - v2.0.0 If the `version` attribute is `2.1.0`, GitLab uses tag `v2.0.0`. And when the version is `1.1.1`, or `1.2.0`, GitLab uses tag v1.1.0. The tag `v1.0.0-pre1` is never used, because pre-release tags are ignored. If `from` is unspecified and no tag to use is found, the API produces an error. To solve such an error, you must explicitly specify a value for the `from` attribute. ### Examples These examples use [cURL](https://curl.se/) to perform HTTP requests. The example commands use these values: - **Project ID**: 42 - **Location**: hosted on GitLab.com - **Example API token**: `token` This command generates a changelog for version `1.0.0`. The commit range: - Starts with the tag of the last release. - Ends with the last commit on the target branch. The default target branch is the project's default branch. If the last tag is `v0.9.0` and the default branch is `main`, the range of commits included in this example is `v0.9.0..main`: ```shell curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0" "https://gitlab.com/api/v4/projects/42/repository/changelog" ``` To generate the data on a different branch, specify the `branch` parameter. This command generates data from the `foo` branch: ```shell curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0&branch=foo" "https://gitlab.com/api/v4/projects/42/repository/changelog" ``` To use a different trailer, use the `trailer` parameter: ```shell curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0&trailer=Type" "https://gitlab.com/api/v4/projects/42/repository/changelog" ``` To store the results in a different file, use the `file` parameter: ```shell curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0&file=NEWS" "https://gitlab.com/api/v4/projects/42/repository/changelog" ``` ## Generate changelog data > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/345934) in GitLab 14.6. Generate changelog data based on commits in a repository, without committing them to a changelog file. Works exactly like `POST /projects/:id/repository/changelog`, except the changelog data isn't committed to any changelog file. ```plaintext GET /projects/:id/repository/changelog ``` Supported attributes: | Attribute | Type | Required | Description | | :-------- | :------- | :--------- | :---------- | | `version` | string | yes | The version to generate the changelog for. The format must follow [semantic versioning](https://semver.org/). | | `config_file` | string | no | The path of changelog configuration file in the project's Git repository, defaults to `.gitlab/changelog_config.yml`. | | `date` | datetime | no | The date and time of the release, ISO 8601 formatted. Example: `2016-03-11T03:45:40Z`. Defaults to the current time. | | `from` | string | no | The start of the range of commits (as a SHA) to use for generating the changelog. This commit itself isn't included in the list. | | `to` | string | no | The end of the range of commits (as a SHA) to use for the changelog. This commit _is_ included in the list. Defaults to the HEAD of the default project branch. | | `trailer` | string | no | The Git trailer to use for including commits, defaults to `Changelog`. | ```shell curl --header "PRIVATE-TOKEN: token" "https://gitlab.com/api/v4/projects/42/repository/changelog?version=1.0.0" ``` Example Response: ```json { "notes": "## 1.0.0 (2021-11-17)\n\n### feature (2 changes)\n\n- [Title 2](namespace13/project13@ad608eb642124f5b3944ac0ac772fecaf570a6bf) ([merge request](namespace13/project13!2))\n- [Title 1](namespace13/project13@3c6b80ff7034fa0d585314e1571cc780596ce3c8) ([merge request](namespace13/project13!1))\n" } ``` ## Related topics - User documentation for [changelogs](../user/project/changelogs.md) - Developer documentation for [changelog entries](../development/changelog.md) in GitLab.
