+# Changelog Configuration
+# This file configures the valid values for changelog fields using the pivot structure.
+# Place this file as `changelog.yml` in the `docs/` directory
+#
+# NOTE: All list-like fields accept BOTH forms:
+#   - Comma-separated string: "value1, value2, value3"
+#   - YAML list:
+#     - value1
+#     - value2
+#     - value3
+# Both forms produce the same result. Choose whichever is more readable for your use case.
+
+# Filename strategy for generated changelog files.
+# Controls how files created by 'changelog add' are named.
+#   pr        — use the PR number (e.g., 12345.yaml).
+#   issue     — use the issue number (e.g., 67890.yaml).
+#   timestamp — use a Unix timestamp with a title slug (e.g., 1735689600-fix-search.yaml). Default.
+# Can be overridden per invocation with --use-pr-number or --use-issue-number CLI flags.
+filename: pr
+
+# Products configuration (optional)
+# If not specified, all products from products.yml are allowed (including those
+# that have 'public-reference' disabled).
+products:
+  # List of available product IDs (empty = all from products.yml)
+  # Accepts string or list: "elasticsearch, kibana" or [elasticsearch, kibana]
+  available: []
+  # Default products when --products not specified
+  default:
+    - product: elasticsearch
+      lifecycle: ga
+
+# Extraction configuration
+# Controls automatic extraction of information from PR descriptions
+extract:
+  # Auto-extract release notes from PR descriptions (default: true)
+  # Can be overridden by CLI --no-extract-release-notes
+  release_notes: true
+  # Auto-extract linked references (default: true)
+  # When using --prs: looks for patterns like "Fixes #123", "Closes #456" in PR body to derive issues.
+  # When using --issues: looks for patterns like "Fixed by #123" in issue body to derive PRs.
+  # Can be overridden by CLI --no-extract-issues
+  issues: true
+  # Remove square-bracket prefixes from PR titles (default: false)
+  # When enabled (true or via --strip-title-prefix), titles like "[ES|QL] Fix bug" become "Fix bug".
+  # Can be overridden by CLI --strip-title-prefix
+  strip_title_prefix: true
+
+# Available lifecycle values (strongly typed: preview, beta, ga)
+# Accepts string or list: "preview, beta, ga" or a YAML list
+lifecycles:
+  - preview
+  - beta
+  - ga

+# Pivot configuration for types, subtypes, and areas with label mappings.
+# By default we render changelogs grouped by type > subtype > area.
+# NOTE: subtype and area are optional and either may be omitted.
+# Labels are specified in a "label -> value" format
+pivot:
+  # Type definitions with optional labels
+  # At a minimum, feature, bug-fix, and breaking-change must be configured.
+  # Keys are type names, values can be:
+  #   - simple string: comma-separated label list (e.g., ">bug, >fix")
+  #   - YAML list: [">bug", ">fix"]
+  #   - empty/null: no labels for this type
+  #   - object: { labels: "...", subtypes: {...} } for breaking-change type only
+  #     (labels and subtype values also accept string or list)
+  types:
+    # Complex object form with subtypes (ONLY allowed for breaking-change)
+    # Subtypes help categorize breaking changes by their nature
+    # Both labels and subtype values accept string or list form
+    breaking-change:
+      # labels: ">breaking, >bc"
+      # Equivalent list form:

+  # Area definitions with labels
+  # Keys are area display names (can contain commas), values are label strings or lists
+  # Each label maps to exactly one area.
+  # String form: "label1, label2" | List form: [label1, label2]
+  # To map one label to multiple areas, repeat the label under each area name.
+  areas:
+    # Example mappings - customize based on your label naming conventions
+    Machine Learning: ":ml"
+    # Watcher: ":Data Management/Watcher"
+    # To map a label to multiple areas (e.g., "Team:Search" to both "Search" and "Observability"):

+    #   - ":Search/Search"
+    #   - "Team:Search"
+    # Observability:
+    #   - "Team:Search"
+    # List form example:
+    # Search:
+    #   - ":Search/Search"
+    #   - ":Search/Ranking"
+
+  # Product definitions with labels (optional).
+  # Keys are product spec strings; values are label strings or lists that trigger that product.
+  # A product spec string is: "<product-id> [<target-version>] [<lifecycle>]"
+  #   - Product ID only:           "elasticsearch"
+  #   - Product + target:          "kibana 9.2.0"

+
+  # Feature ID definitions with labels (optional).
+  # Keys are feature-id values written to the changelog; values are label strings or lists.
+  # When a PR has a matching label and --feature-id is not set, that feature-id is applied.
+  # If multiple labels map to distinct feature-ids, a warning is emitted and the first match is used.

+#   - YAML list: [value1, value2, value3]
+#
+# For details and examples, refer to the [rules documentation](https://github.com/elastic/docs-builder/blob/main/docs/contribute/configure-changelogs-ref.md#rules).
+rules:

+  #     'elasticsearch, kibana':

+
+  # Bundle — filtering applied during 'changelog bundle' and 'changelog gh-release'.
+  # See https://github.com/elastic/docs-builder/blob/main/docs/contribute/configure-changelogs-ref.md#rules-bundle for Mode 1 / 2 / 3 behavior.
+  #
+  # Mode 2 (global content): use global lists only — no `products` key, or `products: {}`.
+  # Example — include changelogs that list elasticsearch OR kibana (evaluated per changelog):
+  # bundle:
+  #   match_products: any
+  #   include_products:
+  #     - elasticsearch
+  #     - kibana
+  #   exclude_types: "deprecation, known-issue"
+  #
+  # Example — exclude only when the changelog lists BOTH products (conjunction); extras allowed:
+  # bundle:
+  #   match_products: conjunction
+  #   exclude_products:
+  #     - kibana
+  #     - observability
+  #
+  # Mode 3 (per-product context): non-empty `rules.bundle.products` — global include/exclude/type/area
+  # under `bundle:` are NOT applied for filtering; configure filters under each product key.
+  # Example:
+  # bundle:
+  #   exclude_types: [docs]   # ignored for filtering in Mode 3 — duplicate under each product if needed
+  #   products:
+  #     observability:
+  #       exclude_products: ["cloud-enterprise"]
+  #       exclude_types: ["docs"]
+  #       include_areas:
+  #         - "APM"
+  #         - "Infrastructure monitoring"
+  #     kibana:
+  #       match_products: all
+  #       include_products: ["kibana", "security"]
+  #       exclude_types: ["docs"]
+
+# Bundle configuration (profiles and defaults)

+  # Run `changelog init` in a GitHub clone to pre-fill owner, repo, and link_allow_repos, or set

+  # link_allow_repos:
+  #   - elastic/kibana
+  # To allow cross-repo links, add more owner/repo entries (for example elastic/elasticsearch).
+  # Optional: default GitHub repo name applied to all profiles that do not specify their own.

+    #   products: "elasticsearch {version} {lifecycle}"
