+prelude: >
+    Replace this text with content to appear at the top of the section for this
+    release. All of the prelude content is merged together and then rendered
+    separately from the items listed in other parts of the file, so the text
+    needs to be worded so that both the prelude and the other items make sense
+    when read independently. This may mean repeating some details. Not every
+    release note requires a prelude. Usually only notes describing major
+    features or adding release theme details should have a prelude.
+features:
+  - |
+    List new features here, or remove this section.  All of the list items in
+    this section are combined when the release notes are rendered, so the text
+    needs to be worded so that it does not depend on any information only
+    available in another section, such as the prelude. This may mean repeating
+    some details.
+issues:
+  - |
+    List known issues here, or remove this section.  All of the list items in
+    this section are combined when the release notes are rendered, so the text
+    needs to be worded so that it does not depend on any information only
+    available in another section, such as the prelude. This may mean repeating
+    some details.
+upgrade:

+    this section are combined when the release notes are rendered, so the text
+    needs to be worded so that it does not depend on any information only
+    available in another section, such as the prelude. This may mean repeating

+deprecations:
+  - |
+    List deprecations notes here, or remove this section.  All of the list
+    items in this section are combined when the release notes are rendered, so
+    the text needs to be worded so that it does not depend on any information
+    only available in another section, such as the prelude. This may mean
+    repeating some details.
+critical:

+    Add critical notes here, or remove this section.  All of the list items in
+    this section are combined when the release notes are rendered, so the text

+fixes:
+  - |
+    Add normal bug fixes here, or remove this section.  All of the list items
+    in this section are combined when the release notes are rendered, so the
+    text needs to be worded so that it does not depend on any information only
