 # Updates should conform to the guidelines in https://keepachangelog.com/en/1.1.0/.
 # [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.
+#
 
-# ## 4.1.1 (2023-07-20)
-
+# ## 5.1.2 (2023-11-08)
+#
+# ### Added
+#
+# - Hide manual_mount warning messages from non-debug output.
+#   Set the DEBUG environment variable to see all hidden messages.
+#
+# ## 5.1.1 (2023-10-30)
+#
+# ### Added
+#
+# - Support for Datadog and Oracle data source plugins repositories.
+#
+# ## 5.1.0 (2023-10-20)
+#
+# ### Added
+#
+# - Support for the plugins monorepo.
+#
+# ## 5.0.0 (2023-10-18)
+#
+# ### Added
+#
+# - Improved support for website repository.
+#
+#   Mount more content and provide some feedback to users that the build can take time.
+#
+# - Ability to enter the `grafana/docs-base` container with a shell using the `ENTER` environment variable.
+#
 # ### Fixed
+#
+# - Correct key combination for interrupting the process.
+#
+#   Keyboards use capital letters so this more accurately reflects the exact key combination users are expected to press.
+#
+# ### Removed
+#
+# - Imperfect implementation of container name.
+#
+#   Facilitates running `make vale` and `make docs` at once.
+#   Container names are convenient for recognition in `docker ps` but the current implementation has more downsides than upsides.
+#
+# - Forced platform specification now that multiple architecture images exist.
+#
+#  Significantly speeds up build times on larger repositories.
+#
+# ## 4.2.2 (2023-10-05)
 
-# - Replaced use of `realpath` with POSIX compatible alternative to determine default value for REPOS_PATH.
+# - Added support for Jira data source and MongoDB data source plugins repositories.
+#
+# ## 4.2.1 (2023-09-13)
 
+# ## Fixed
+#
+# - Improved consistency of the webserver request loop by polling the Hugo port rather than the proxy port.
+#
+# ## 4.2.0 (2023-09-01)
+#
+# ### Added
+#
+# - Retry the initial webserver request up to ten times to allow for the process to start.
+#   If it is still failing after ten seconds, an error message is logged.
+#
+# ## 4.1.1 (2023-07-20)
+#
+# ### Fixed
+#
+# - Replaced use of `realpath` with POSIX compatible alternative to determine default value for REPOS_PATH.
+#
 # ## 4.1.0 (2023-06-16)
-
+#
 # ### Added
-
+#
 # - Mounts of `layouts` and `config` directories for the `website` project.
 #   Ensures that local changes to mounts or shortcodes are reflected in the development server.
-
+#
 # ### Fixed
-
+#
 # - Version inference for versioned docs pages.
 #   Pages in versioned projects now have the `versioned: true` front matter set to ensure that "version" in $.Page.Scratch is set on builds.
-
+#
 # ## 4.0.0 (2023-06-06)
-
+#
 # ### Removed
-
+#
 # - `doc-validator/%` target.
 #   The behavior of the target was not as described.
 #   Instead, to limit `doc-validator` to only specific files, refer to https://grafana.com/docs/writers-toolkit/writing-guide/tooling-and-workflows/validate-technical-documentation/#run-on-specific-files.
-
+#
 # ## 3.0.0 (2023-05-18)
-
+#
 # ### Fixed
-
+#
 # - Compatibility with the updated Make targets in the `website` repository.
 #   `docs` now runs this script itself, `server-docs` builds the site with the `docs` Hugo environment.
-
+#
 # ## 2.0.0 (2023-05-18)
-
+#
 # ### Added
-
+#
 # - Support for the grafana-cloud/frontend-observability/faro-web-sdk project.
 # - Use of `doc-validator` v2.0.x which includes breaking changes to command line options.
-
+#
 # ### Fixed
-
+#
 # - Source grafana-cloud project from website repository.
-
+#
 # ### Added
-
+#
 # - Support for running the Vale linter with `make vale`.
-
+#
 # ## 1.2.1 (2023-05-05)
-
+#
 # ### Fixed
-
+#
 # - Use `latest` tag of `grafana/vale` image by default instead of hardcoded older version.
 # - Fix mounting multiple projects broken by the changes in 1.0.1
-
+#
 # ## 1.2.0 (2023-05-05)
-
+#
 # ### Added
-
+#
 # - Support for running the Vale linter with `make vale`.
-
+#
 # ### Fixed
-
+#
 # ## 1.1.0 (2023-05-05)
-
+#
 # ### Added
-
+#
 # - Rewrite error output so it can be followed by text editors.
-
+#
 # ### Fixed
-
+#
 # - Fix `docs-debug` container process port.
-
+#
 # ## 1.0.1 (2023-05-04)
-
+#
 # ### Fixed
-
+#
 # - Ensure complete section hierarchy so that all projects have a visible menu.
-
+#
 # ## 1.0.0 (2023-05-04)
-
+#
 # ### Added
-
+#
 # - Build multiple projects simultaneously if all projects are checked out locally.
 # - Run [`doc-validator`](https://github.com/grafana/technical-documentation/tree/main/tools/cmd/doc-validator) over projects.
 # - Redirect project root to mounted version.
