# Create and bundle changelogs
By adding a file for each notable change and grouping them into bundles, you can ultimately generate release documention with a consistent layout for all your products.
The changelogs use the following schema:
<dropdown title="Changelog schema">
  ```yaml
  ##### Required fields #####
  title:

  # A required string that is a short, user-facing headline
  # Max 80 characters

  type: 

  # A required string that contains the type of change.
  # For the acceptable values, refer to https://github.com/elastic/docs-builder/blob/main/src/Elastic.Documentation/ChangelogEntryType.cs
  products:

  # A required array of objects that denote the affected products and their target release.

      - product:

        # A required string with a predefined product ID used for release note routing,
        # filters, and categorization.
        # Refer to https://github.com/elastic/docs-builder/blob/main/config/products.yml for the acceptable values.

        target:

        # An optional string that facilitates pre-release doc previews.
        # For products with version releases, it contains the target version number (V.R.M).
        # For products with date releases, it contains the target release date
        # or the date the PR was merged.

        lifecycle:

        # An optional string for new features and enhancements that have a specific availability.
        # For the acceptable values, refer to https://github.com/elastic/docs-builder/blob/main/src/Elastic.Documentation/Lifecycle.cs

  ##### Optional fields #####
  action:

  # An optional string that describes what users must do to mitigate the impact
  # of a breaking change or known issue.

  areas:

  # An optional array of strings that denotes the parts/components/services of the
  # product that are specifically affected.
  # The list of valid values will vary by product.
  # The docs for each release typically group the changes by type then by area.

  description:

  # An optional string that provides additional information about what has changed.
  # Max 600 characters

  feature-id:

  # An optional string to associate a feature or enhancement with a unique feature flag

  highlight:

  # An optional boolean for items that should be included in release highlights
  # or the UI to draw users' attention.

  impact:

  # An optional string that describes how the user's environment is/will be
  # affected by a breaking change.

  issues:

  # An optional array of strings that contain URLs for issues that are relevant to the PR.
  # They are externalized in the release docs so users can follow the links and
  # understand the context.

  pr: 

  # An optional string that contains the pull request identifier.
  # It is externalized in the release docs so users can follow the link and find more details.

  subtype:

  # An optional string that applies only to breaking changes and further subdivides that type.
  # For the acceptable values, refer to https://github.com/elastic/docs-builder/blob/main/src/Elastic.Documentation/ChangelogEntrySubtype.cs
  ```
</dropdown>

<important>
  Some of the fields in the schema accept only a specific set of values:
  - Product values must exist in [products.yml](https://github.com/elastic/docs-builder/blob/main/config/products.yml). Invalid products will cause the `docs-builder changelog add` command to fail.
  - Type, subtype, and lifecycle values must match the available values defined in [ChangelogEntryType.cs](https://github.com/elastic/docs-builder/blob/main/src/Elastic.Documentation/ChangelogEntryType.cs), [ChangelogEntrySubtype.cs](https://github.com/elastic/docs-builder/blob/main/src/Elastic.Documentation/ChangelogEntrySubtype.cs), and [Lifecycle.cs](https://github.com/elastic/docs-builder/blob/main/src/Elastic.Documentation/Lifecycle.cs) respectively. Invalid values will cause the `docs-builder changelog add` command to fail.
</important>

To use the `docs-builder changelog` commands in your development workflow:
1. Ensure that your products exist in [products.yml](https://github.com/elastic/docs-builder/blob/main/config/products.yml).
2. Add labels to your GitHub pull requests that map to [changelog types](https://github.com/elastic/docs-builder/blob/main/src/Elastic.Documentation/ChangelogEntryType.cs). At a minimum, create labels for the `feature`, `bug-fix`, and `breaking-change` types.
3. Optional: Choose areas or components that your changes affect and add labels to your GitHub pull requests (such as `:Analytics/Aggregations`).
4. Optional: Add labels to your GitHub pull requests to indicate that they are not notable and should not generate changelogs. For example, `non-issue` or `release_notes:skip`. Alternatively, you can assume that all PRs are *not* notable unless a specific label is present (for example, `@Public`).
5. [Configure changelog settings](#changelog-settings) to correctly interpret your PR labels.
6. [Create changelogs](#changelog-add) with the `docs-builder changelog add` command.
7. [Create changelog bundles](#changelog-bundle) with the `docs-builder changelog bundle` command. For example, create a bundle for the pull requests that are included in a product release.
8. [Create documentation](#render-changelogs) with the `docs-builder changelog render` command.

For more information about running `docs-builder`, go to [Contribute locally](https://www.elastic.co/docs/contribute-docs/locally).
<note>
  This command is associated with an ongoing release docs initiative.
  Additional workflows are still to come for updating and generating documentation from changelogs.
</note>


## Create a changelog configuration file

You can create a configuration file to:
- define the acceptable product, type, subtype, and lifecycle values.
- prevent the creation of changelogs when certain PR labels are present.
- set default options, such as whether to extract issues and release note text from pull requests.

Refer to [changelog.example.yml](https://github.com/elastic/docs-builder/blob/main/config/changelog.example.yml).
By default, the `docs-builder changelog add` command checks the following path: `docs/changelog.yml`.
You can specify a different path with the `--config` command option.
If a configuration file exists, the command validates its values before generating changelog files:
- If the configuration file contains `lifecycles`, `products`, `subtype`, or `type` values that don't match the values in `ChangelogEntryType.cs`, `ChangelogEntrySubtype.cs`, or `Lifecycle.cs`, validation fails.
- If the configuration file contains `areas` values and they don't match what you specify in the `--areas` command option, validation fails.
- If the configuration file contains `lifecycles` or `products` values are a subset of the available values and you try to create a changelog with values outside that subset, validation fails.

In each of these cases where validation fails, a changelog file is not created.

### GitHub label mappings

When you run the `docs-builder changelog add` command with the `--prs` option, it can use label mappings in the changelog configuration file to infer the changelog `type` and `areas` fields from your pull request labels.
Refer to the file layout in [changelog.example.yml](https://github.com/elastic/docs-builder/blob/main/config/changelog.example.yml) and an [example usage](#example-map-label).

### Block creation or publishing

If you have pull request labels that indicate a changelog is not required (such as `>non-issue` or `release_note:skip`), you can declare these in the `block` section of the changelog configuration.
When you run the `docs-builder changelog add` command with the `--prs` option and the PR has one of the identified labels, the command does not create a changelog for that PR.
Likewise, if there are areas or types of changelogs that should not be published, you can declare these in the `block` section of the changelog configuration.
For example, you might choose to omit `other` or `docs` changelogs.
Or you might want to omit all autoscaling-related changelogs from the Cloud Serverless release docs.
When you run the `docs-builder changelog render` command, changelog entries that match the specified products and areas or types are commented out of the documentation output files.
The command will emit warnings indicating which changelog entries were commented out and why.
<note>
  You can define blocks at the global level (applies to all products) or for specific products.
  Product-specific blocks **override** the global blocks entirely—they do not merge.
  If you define a product-specific `publish.areas` block, you must re-state any global blocked areas that you also want blocked for that product.
</note>

Refer to [changelog.example.yml](https://github.com/elastic/docs-builder/blob/main/config/changelog.example.yml) and an [example usage](#example-block-label).

## Create changelog files

You can use the `docs-builder changelog add` command to create a changelog file.
<tip>
  Ideally this task will be automated such that it's performed by a bot or GitHub action when you create a pull request. More details to come as we refine the workflows.
</tip>

For up-to-date command usage information, use the `-h` option:
```sh
Add a new changelog from command-line input

Options:
  --products <List<ProductArgument>?>    Optional: Products affected in format "product target lifecycle, ..." (e.g., "elasticsearch 9.2.0 ga, cloud-serverless 2025-08-05"). If not specified, will be inferred from repository or config defaults. [Default: null]
  --action <string?>                     Optional: What users must do to mitigate [Default: null]
  --areas <string[]?>                    Optional: Area(s) affected (comma-separated or specify multiple times) [Default: null]
  --config <string?>                     Optional: Path to the changelog.yml configuration file. Defaults to 'docs/changelog.yml' [Default: null]
  --description <string?>                Optional: Additional information about the change (max 600 characters) [Default: null]
  --no-extract-release-notes             Optional: Turn off extraction of release notes from PR descriptions. By default, release notes are extracted when using --prs. Short release notes (≤120 characters, single line) are used as the title, long release notes (>120 characters or multi-line) are used as the description.
  --no-extract-issues                    Optional: Turn off extraction of linked issues from PR body (e.g., "Fixes #123"). By default, linked issues are extracted when using --prs.
  --feature-id <string?>                 Optional: Feature flag ID [Default: null]
  --highlight <bool?>                    Optional: Include in release highlights [Default: null]
  --impact <string?>                     Optional: How the user's environment is affected [Default: null]
  --issues <string[]?>                   Optional: Issue URL(s) (comma-separated or specify multiple times) [Default: null]
  --owner <string?>                      Optional: GitHub repository owner (used when --prs contains just numbers) [Default: null]
  --output <string?>                     Optional: Output directory for the changelog. Defaults to current directory [Default: null]
  --prs <string[]?>                      Optional: Pull request URL(s) or PR number(s) (comma-separated), or a path to a newline-delimited file containing PR URLs or numbers. Can be specified multiple times. Each occurrence can be either comma-separated PRs (e.g., `--prs "https://github.com/owner/repo/pull/123,6789"`) or a file path (e.g., `--prs /path/to/file.txt`). When specifying PRs directly, provide comma-separated values. When specifying a file path, provide a single value that points to a newline-delimited file. If --owner and --repo are provided, PR numbers can be used instead of URLs. If specified, --title can be derived from the PR. If mappings are configured, --areas and --type can also be derived from the PR. Creates one changelog file per PR. [Default: null]
  --repo <string?>                       Optional: GitHub repository name (used when --prs contains just numbers) [Default: null]
  --strip-title-prefix                   Optional: When used with --prs, remove square brackets and text within them from the beginning of PR titles, and also remove a colon if it follows the closing bracket (e.g., "[Inference API] Title" becomes "Title", "[ES|QL]: Title" becomes "Title", "[Discover][ESQL] Title" becomes "Title")
  --subtype <string?>                    Optional: Subtype for breaking changes (api, behavioral, configuration, etc.) [Default: null]
  --title <string?>                      Optional: A short, user-facing title (max 80 characters). Required if --pr is not specified. If --pr and --title are specified, the latter value is used instead of what exists in the PR. [Default: null]
  --type <string?>                       Optional: Type of change (feature, enhancement, bug-fix, breaking-change, etc.). Required if --pr is not specified. If mappings are configured, type can be derived from the PR. [Default: null]
  --use-pr-number                        Optional: Use the PR number as the filename instead of generating it from a unique ID and title
```


### Authorization

If you use the `--prs` option, the `docs-builder changelog add` command interacts with GitHub services.
Log into GitHub or set the `GITHUB_TOKEN` (or `GH_TOKEN` ) environment variable with a sufficient personal access token (PAT).
Otherwise, there will be fetch failures when you access private repositories and you might also encounter GitHub rate limiting errors.
For example, to create a new token with the minimum authority to read pull request details:
1. Go to **GitHub Settings** > **Developer settings** > **Personal access tokens** > [Fine-grained tokens](https://github.com/settings/personal-access-tokens).
2. Click **Generate new token**.
3. Give your token a descriptive name (such as "docs-builder changelog").
4. Under **Resource owner** if you're an Elastic employee, select **Elastic**.
5. Set an expiration date.
6. Under **Repository access**, select **Only select repositories** and choose the repositories you want to access.
7. Under **Permissions** > **Repository permissions**, set **Pull requests** to **Read-only**.
8. Click **Generate token**.
9. Copy the token to a safe location and use it in the `GITHUB_TOKEN` environment variable.


### Product format

The `docs-builder changelog add` has a `--products` option and the `docs-builder changelog bundle` has `--input-products` and `--output-products` options that all use the same format.
They accept values with the format `"product target lifecycle, ..."` where:
- `product` is the product ID from [products.yml](https://github.com/elastic/docs-builder/blob/main/config/products.yml) (required)
- `target` is the target version or date (optional)
- `lifecycle` is one of: `preview`, `beta`, or `ga` (optional)

Examples:
- `"kibana 9.2.0 ga"`
- `"cloud-serverless 2025-08-05"`
- `"cloud-enterprise 4.0.3, cloud-hosted 2025-10-31"`


### Filenames

By default, the `docs-builder changelog add` command generates filenames using a timestamp and a sanitized version of the title:
`{timestamp}-{sanitized-title}.yaml`
For example: `1735689600-fixes-enrich-and-lookup-join-resolution.yaml`
If you want to use the PR number as the filename instead, add the `--use-pr-number` option:
```sh
docs-builder changelog add \
  --pr https://github.com/elastic/elasticsearch/pull/137431 \
  --products "elasticsearch 9.2.3" \
  --use-pr-number
```

This creates a file named `137431.yaml` instead of the default timestamp-based filename.
<important>
  When using `--use-pr-number`, you must also provide the `--pr` option. The PR number is extracted from the PR URL or number you provide.
</important>


### Examples


#### Create a changelog for multiple products

```sh
docs-builder changelog add \
  --title "Fixes enrich and lookup join resolution based on minimum transport version" \ 
  --type bug-fix \ 
  --products "elasticsearch 9.2.3, cloud-serverless 2025-12-02" \ 
  --areas "ES|QL"
  --prs "https://github.com/elastic/elasticsearch/pull/137431" 
```


#### Create a changelog with PR label mappings

You can configure label mappings in your changelog configuration file:
```yaml
pivot:
  # Keys are type names, values can be:
  #   - simple string: comma-separated label list (e.g., ">bug, >fix")
  #   - empty/null: no labels for this type
  #   - object: { labels: "...", subtypes: {...} } for breaking-change type only
  types:
    # Example mappings - customize based on your label naming conventions
    breaking-change:
      labels: ">breaking, >bc"
    bug-fix: ">bug"
    enhancement: ">enhancement"
  
  # Area definitions with labels
  # Keys are area display names, values are label strings
  # Multiple labels can be comma-separated
  areas:
    # Example mappings - customize based on your label naming conventions
    Autoscaling: ":Distributed Coordination/Autoscaling"
    "ES|QL": ":Search Relevance/ES|QL"
```

When you use the `--prs` option to derive information from a pull request, it can make use of those mappings:
```sh
docs-builder changelog add \
  --prs https://github.com/elastic/elasticsearch/pull/139272 \
  --products "elasticsearch 9.3.0" \
  --config test/changelog.yml \
  --strip-title-prefix
```

In this case, the changelog file derives the title, type, and areas from the pull request.
The command also looks for patterns like `Fixes #123`, `Closes owner/repo#456`, `Resolves https://github.com/.../issues/789` in the pull request to derive its issues (unless you turn off this behavior in the changelog configuration file or use `--no-extract-issues`).
The `--strip-title-prefix` option in this example means that if the PR title has a prefix in square brackets (such as `[ES|QL]` or `[Security]`), it is automatically removed from the changelog title. Multiple square bracket prefixes are also supported (e.g., `[Discover][ESQL] Title` becomes `Title`). If a colon follows the closing bracket, it is also removed.
<note>
  The `--strip-title-prefix` option only applies when the title is derived from the PR (when `--title` is not explicitly provided). If you specify `--title` explicitly, that title is used as-is without any prefix stripping.
</note>


#### Extract release notes from PR descriptions

When you use the `--prs` option, by default the `docs-builder changelog add` command automatically extracts text from the PR descriptions and use it in your changelog.
In particular, it looks for content in these formats in the PR description:
- `Release Notes: This is the extracted sentence.`
- `Release-Notes: This is the extracted sentence.`
- `release notes: This is the extracted sentence.`
- `Release Note: This is the extracted sentence.`
- `Release Notes - This is the extracted sentence.`
- `## Release Note` (as a markdown header)

The extracted content is handled differently based on its length:
- **Short release notes (≤120 characters, single line)**: Used as the changelog title (only if `--title` is not explicitly provided)
- **Long release notes (>120 characters or multi-line)**: Used as the changelog description (only if `--description` is not explicitly provided)
- **No release note found**: No changes are made to the title or description

<note>
  If you explicitly provide `--title` or `--description`, those values take precedence over extracted release notes.
  You can turn off the release note extraction in the changelog configuration file or by using the `--no-extract-release-notes` option.
</note>


#### Block changelog creation and publishing

You can prevent changelog creation for certain PRs based on their labels.
You can likewise refrain from publishing changelogs based on their areas and types.
If you run the `docs-builder changelog add` command with the `--prs` option and a PR has a blocking label for any of the products in the `--products` option, that PR will be skipped and no changelog file will be created for it.
A warning message will be emitted indicating which PR was skipped and why.
For example, your configuration file can contain a `block` section this:
```yaml
block:
  # Global labels that block changelog creation for all products (comma-separated string)
  create: ">non-issue"
  # Block changelog entries from publishing based on entry type or area
  publish:
    types:
      - docs
    areas:
      - "Internal"
  product:
    'cloud-serverless':
      create: ">non-issue, >test"
      publish:
        areas:
          - "Internal"
          - "Autoscaling"
          - "Watcher"
    'elasticsearch, kibana':
      publish:
        types:
          - docs
          - other
```

Those settings affect commands with the `--prs` option, for example:
```sh
docs-builder changelog add --prs "1234, 5678" \
  --products "cloud-serverless" \
  --owner elastic --repo elasticsearch \
  --config test/changelog.yml
```

If PR 1234 has the `>non-issue` or `>test` labels, it will be skipped and no changelog will be created.
If PR 5678 does not have any blocking labels, a changelog is created.
The `block` settings also affect the publishing stage.
For example, if you run the `docs-builder changelog render` command for a Cloud Serverless bundle, any changelogs that have "Internal", "Autoscaling", or "Watcher" areas are commmented out.

#### Create changelogs from a file of PRs

You can also provide PRs from a file containing newline-delimited PR URLs or numbers:
```sh
# Create a file with PRs (one per line)
cat > prs.txt << EOF
https://github.com/elastic/elasticsearch/pull/1234
https://github.com/elastic/elasticsearch/pull/5678
EOF

# Use the file with --prs
docs-builder changelog add --prs prs.txt \
  --products "elasticsearch 9.2.0 ga" \
  --config test/changelog.yml
```

You can also mix file paths and comma-separated PRs:
```sh
docs-builder changelog add \
  --prs "https://github.com/elastic/elasticsearch/pull/1234" \
  --prs prs.txt \
  --prs "5678, 9012" \
  --products "elasticsearch 9.2.0 ga" \
  --owner elastic --repo elasticsearch \
  --config test/changelog.yml
```

This creates one changelog file for each PR specified, whether from files or directly.

## Create bundles

You can use the `docs-builder changelog bundle` command to create a YAML file that lists multiple changelogs.
For up-to-date details, use the `-h` option:
```sh
Bundle changelogs

Options:
  --all                                     Include all changelogs in the directory. Only one filter option can be specified: `--all`, `--input-products`, or `--prs`.
  --directory <string?>                     Optional: Directory containing changelog YAML files. Defaults to current directory [Default: null]
  --input-products <List<ProductInfo>?>     Filter by products in format "product target lifecycle, ..." (e.g., "cloud-serverless 2025-12-02 ga, cloud-serverless 2025-12-06 beta"). When specified, all three parts (product, target, lifecycle) are required but can be wildcards (*). Examples: "elasticsearch * *" matches all elasticsearch changelogs, "cloud-serverless 2025-12-02 *" matches cloud-serverless 2025-12-02 with any lifecycle, "* 9.3.* *" matches any product with target starting with "9.3.", "* * *" matches all changelogs (equivalent to --all). Only one filter option can be specified: `--all`, `--input-products`, or `--prs`. [Default: null]
  --output <string?>                        Optional: Output path for the bundled changelog. Can be either (1) a directory path, in which case 'changelog-bundle.yaml' is created in that directory, or (2) a file path ending in .yml or .yaml. Defaults to 'changelog-bundle.yaml' in the input directory [Default: null]
  --output-products <List<ProductInfo>?>    Optional: Explicitly set the products array in the output file in format "product target lifecycle, ...". Overrides any values from changelogs. [Default: null]
  --owner <string?>                         GitHub repository owner (required only when PRs are specified as numbers) [Default: null]
  --prs <string[]?>                         Filter by pull request URLs or numbers (comma-separated), or a path to a newline-delimited file containing PR URLs or numbers. Can be specified multiple times. Only one filter option can be specified: `--all`, `--input-products`, or `--prs`. [Default: null]
  --repo <string?>                          GitHub repository name (required only when PRs are specified as numbers) [Default: null]
  --resolve                                 Optional: Copy the contents of each changelog file into the entries array. By default, the bundle contains only the file names and checksums.
```

You can specify only one of the following filter options:
- `--all`: Include all changelogs from the directory.
- `--input-products`: Include changelogs for the specified products. Refer to [Filter by product](#changelog-bundle-product).
- `--prs`: Include changelogs for the specified pull request URLs or numbers, or a path to a newline-delimited file containing PR URLs or numbers. Go to [Filter by pull requests](#changelog-bundle-pr).

By default, the output file contains only the changelog file names and checksums.
You can optionally use the `--resolve` command option to pull all of the content from each changelog into the bundle.

### Filter by product

You can use the `--input-products` option to create a bundle of changelogs that match the product details.
When using `--input-products`, you must provide all three parts: product, target, and lifecycle.
Each part can be a wildcard (`*`) to match any value.
```sh
docs-builder changelog bundle \
  --input-products "cloud-serverless 2025-12-02 ga, cloud-serverless 2025-12-06 beta" 
```

You can use wildcards in any of the three parts:
```sh
# Bundle any changelogs that have exact matches for either of these clauses
docs-builder changelog bundle --input-products "cloud-serverless 2025-12-02 ga, elasticsearch 9.3.0 beta"

# Bundle all elasticsearch changelogs regardless of target or lifecycle
docs-builder changelog bundle --input-products "elasticsearch * *"

# Bundle all cloud-serverless 2025-12-02 changelogs with any lifecycle
docs-builder changelog bundle --input-products "cloud-serverless 2025-12-02 *"

# Bundle any cloud-serverless changelogs with target starting with "2025-11-" and "ga" lifecycle
docs-builder changelog bundle --input-products "cloud-serverless 2025-11-* ga"

# Bundle all changelogs (equivalent to --all)
docs-builder changelog bundle --input-products "* * *"
```

If you have changelog files that reference those product details, the command creates a file like this:
```yaml
products: 
- product: cloud-serverless
  target: 2025-12-02
- product: cloud-serverless
  target: 2025-12-06
entries:
- file:
    name: 1765495972-fixes-enrich-and-lookup-join-resolution-based-on-m.yaml
    checksum: 6c3243f56279b1797b5dfff6c02ebf90b9658464
- file:
    name: 1765507778-break-on-fielddata-when-building-global-ordinals.yaml
    checksum: 70d197d96752c05b6595edffe6fe3ba3d055c845
```

If you add the `--resolve` option, the contents of each changelog will be included in the output file.

### Filter by pull requests

You can use the `--prs` option to create a bundle of the changelogs that relate to those pull requests.
You can provide either a comma-separated list of PRs (`--prs "https://github.com/owner/repo/pull/123,12345"`) or a path to a newline-delimited file (`--prs /path/to/file.txt`).
In the latter case, the file should contain one PR URL or number per line.
Pull requests can be identified by a full URL (such as `https://github.com/owner/repo/pull/123`), a short format (such as `owner/repo#123`), or just a number (in which case you must also provide `--owner` and `--repo` options).
```sh
docs-builder changelog bundle --prs "108875,135873,136886" \ 
  --repo elasticsearch \ 
  --owner elastic \ 
  --output-products "elasticsearch 9.2.2 ga" 
```

If you have changelog files that reference those pull requests, the command creates a file like this:
```yaml
products:
- product: elasticsearch
  target: 9.2.2
  lifecycle: ga
entries:
- file:
    name: 1765507819-fix-ml-calendar-event-update-scalability-issues.yaml
    checksum: 069b59edb14594e0bc3b70365e81626bde730ab7
- file:
    name: 1765507798-convert-bytestransportresponse-when-proxying-respo.yaml
    checksum: c6dbd4730bf34dbbc877c16c042e6578dd108b62
- file:
    name: 1765507839-use-ivf_pq-for-gpu-index-build-for-large-datasets.yaml
    checksum: 451d60283fe5df426f023e824339f82c2900311e
```

If you add the `--resolve` option, the contents of each changelog will be included in the output file.

### Filter by pull request file

If you have a file that lists pull requests (such as PRs associated with a GitHub release):
```txt
https://github.com/elastic/elasticsearch/pull/108875
https://github.com/elastic/elasticsearch/pull/135873
https://github.com/elastic/elasticsearch/pull/136886
https://github.com/elastic/elasticsearch/pull/137126
```

You can use the `--prs` option with a file path to create a bundle of the changelogs that relate to those pull requests. You can also combine multiple `--prs` options:
```sh
./docs-builder changelog bundle \
  --prs "https://github.com/elastic/elasticsearch/pull/108875,135873" \ 
  --prs test/9.2.2.txt \ 
  --output-products "elasticsearch 9.2.2 ga" 
  --resolve 
```

If you have changelog files that reference those pull requests, the command creates a file like this:
```yaml
products:
- product: elasticsearch
  target: 9.2.2
  lifecycle: ga
entries:
- file:
    name: 1765507778-break-on-fielddata-when-building-global-ordinals.yaml
    checksum: 70d197d96752c05b6595edffe6fe3ba3d055c845
  type: bug-fix
  title: Break on FieldData when building global ordinals
  products:
  - product: elasticsearch
  areas:
  - Aggregations
  pr: https://github.com/elastic/elasticsearch/pull/108875
...
```

<note>
  When a changelog matches multiple `--input-products` filters, it appears only once in the bundle. This deduplication applies even when using `--all` or `--prs`.
</note>


### Output file location

The `--output` option supports two formats:
1. **Directory path**: If you specify a directory path (without a filename), the command creates `changelog-bundle.yaml` in that directory:
   ```sh
   docs-builder changelog bundle --all --output /path/to/output/dir
   # Creates /path/to/output/dir/changelog-bundle.yaml
   ```
2. **File path**: If you specify a file path ending in `.yml` or `.yaml`, the command uses that exact path:
   ```sh
   docs-builder changelog bundle --all --output /path/to/custom-bundle.yaml
   # Creates /path/to/custom-bundle.yaml
   ```

If you specify a file path with a different extension (not `.yml` or `.yaml`), the command returns an error.

## Create documentation


### Include changelogs inline

You can use the [`{changelog}` directive](https://docs-v3-preview.elastic.dev/elastic/docs-builder/pull/2657/syntax/changelog) to render all changelog bundles directly in your documentation pages, without needing to run the `changelog render` command first.
```markdown
:::{changelog}
:::
```

By default, the directive renders all bundles from `changelog/bundles/` (relative to the docset root), ordered by semantic version (newest first). For full documentation and examples, see the [{changelog} directive syntax reference](https://docs-v3-preview.elastic.dev/elastic/docs-builder/pull/2657/syntax/changelog).

### Generate markdown or asciidoc

The `docs-builder changelog render` command creates markdown or asciidoc files from changelog bundles for documentation purposes.
For up-to-date details, use the `-h` command option:
```sh
Render bundled changelog(s) to markdown or asciidoc files

Options:
  --input <string[]?>            Required: Bundle input(s) in format "bundle-file-path|changelog-file-path|repo|link-visibility" (use pipe as delimiter). To merge multiple bundles, separate them with commas. Only bundle-file-path is required. link-visibility can be "hide-links" or "keep-links" (default). Paths must be absolute or use environment variables; tilde (~) expansion is not supported. [Default: null]
  --config <string?>             Optional: Path to the changelog.yml configuration file. Defaults to 'docs/changelog.yml' [Default: null]
  --file-type <string?>          Optional: Output file type. Valid values: "markdown" or "asciidoc". Defaults to "markdown" [Default: @"markdown"]
  --hide-features <string[]?>    Filter by feature IDs (comma-separated), or a path to a newline-delimited file containing feature IDs. Can be specified multiple times. Entries with matching feature-id values will be commented out in the output. [Default: null]
  --output <string?>             Optional: Output directory for rendered files. Defaults to current directory [Default: null]
  --subsections                  Optional: Group entries by area/component in subsections. For breaking changes with a subtype, groups by subtype instead of area. Defaults to false
  --title <string?>              Optional: Title to use for section headers in output files. Defaults to version from first bundle [Default: null]
```

Before you can use this command you must create changelog files and collect them into bundles.
For example, the `docs-builder changelog bundle` command creates a file like this:
```yaml
products:
- product: elasticsearch
  target: 9.2.2
entries:
- file:
    name: 1765581721-convert-bytestransportresponse-when-proxying-respo.yaml
    checksum: d7e74edff1bdd3e23ba4f2f88b92cf61cc7d490a
- file:
    name: 1765581721-fix-ml-calendar-event-update-scalability-issues.yaml
    checksum: dfafce50c9fd61c3d8db286398f9553e67737f07
- file:
    name: 1765581651-break-on-fielddata-when-building-global-ordinals.yaml
    checksum: 704b25348d6daff396259216201053334b5b3c1d
```

To create markdown files from this bundle, run the `docs-builder changelog render` command:
```sh
docs-builder changelog render \
  --input "/path/to/changelog-bundle.yaml|/path/to/changelogs|elasticsearch|keep-links,/path/to/other-bundle.yaml|/path/to/other-changelogs|kibana|hide-links" \ 
  --title 9.2.2 \ 
  --output /path/to/release-notes \ 
  --subsections 
```

<important>
  Paths in the `--input` option must be absolute paths or use environment variables. Tilde (`~`) expansion is not supported.
</important>

For example, the `index.md` output file contains information derived from the changelogs:
```md
## 9.2.2 [elastic-release-notes-9.2.2]

### Fixes [elastic-9.2.2-fixes]

**Network**
* Convert BytesTransportResponse when proxying response from/to local node. [#135873](https://github.com/elastic/elastic/pull/135873) 

**Machine Learning**
* Fix ML calendar event update scalability issues. [#136886](https://github.com/elastic/elastic/pull/136886) 

**Aggregations**
* Break on FieldData when building global ordinals. [#108875](https://github.com/elastic/elastic/pull/108875) 
```

To comment out the pull request and issue links, for example if they relate to a private repository, add `hide-links` to the `--input` option for that bundle. This allows you to selectively hide links per bundle when merging changelogs from multiple repositories.
If you have changelogs with `feature-id` values and you want them to be omitted from the output, use the `--hide-features` option.
For more information, refer to [changelog render](https://docs-v3-preview.elastic.dev/elastic/docs-builder/pull/2657/cli/release/changelog-render).
To create an asciidoc file instead of markdown files, add the `--file-type asciidoc` option:
```sh
docs-builder changelog render \
  --input "./changelog-bundle.yaml,./changelogs,elasticsearch" \
  --title 9.2.2 \
  --output ./release-notes \
  --file-type asciidoc \ 
  --subsections
```
