 # [Semantic versioning](https://semver.org/) is used to help the reader identify the significance of changes.
 # Changes are relevant to this script and the support docs.mk GNU Make interface.
 #
+# ## 8.0.0 (2024-05-28)
+#
+# ### Changed
+#
+# - Add environment variable `OUTPUT_FORMAT` to control the output of commands.
+#
+#   The default value is `human` and means the output format is human readable.
+#   The value `json` is also supported and outputs JSON.
+#
+#   Note that the `json` format isn't supported by `make docs`, only `make doc-validator` and `make vale`.
+#
+# ## 7.0.0 (2024-05-03)
+#
+# ### Changed
+#
+# - Pull images for all recipes that use containers by default.
+#
+#   Use the `PULL=false` variable to disable this behavior.
+#
+# ### Removed
+#
+# - The `docs-no-pull` target as it's redundant with the new `PULL=false` variable.
+#
+# ## 6.1.0 (2024-04-22)
+#
+# ### Changed
+#
+# - Mount volumes with SELinux labels.
+#
+#   https://docs.docker.com/storage/bind-mounts/#configure-the-selinux-label
+#
+# ### Added
+#
+# - Pseudo project for including only website resources and no website content.
+#
+#   Facilitates testing shortcodes and layout changes with a small documentation set instead of Grafana Cloud or the entire website.
+#
 # ## 6.0.1 (2024-02-28)
 #
 # ### Added
