+# Deprecations
+
+This page includes a list of deprecations, indicating which features should not
+be used anymore, as they will be removed in a future release.
+
+## Front matter
+
+### Redirects
+
+:octicons-archive-24: Deprecated: 5.5.0 ·
+:octicons-trash-24: Will be removed in 6.0
+
+The `redirect` key, which could be added via [Metadata][1], allowed to
+specify a redirect URL from within a markdown page to a new address, to notify
+the user when content was moved:
+
+``` markdown
+---
+redirect: /path/to/new/file
+---
+```
+
+The [mkdocs-redirects][2] plugin provides the ability to define redirect
+mappings via `mkdocs.yml`, which is considered to be a much better solution to
+achieve the same result:
+
+``` yaml
+plugins:
+  - search
+  - redirects:
+      redirect_maps:
+        path/to/old/file.md: path/to/new/file.md
+```

+### Linking sources
+
+:octicons-archive-24: Deprecated: 5.5.0 ·
+:octicons-trash-24: Will be removed in 6.0
+
+The `source` and `path` keys, which could be added via [Metadata][1], showed
+a source icon at the top right of a document, linking a document to a single
+source file:
+
+``` markdown
+---
+path: tree/master/docs
+source: deprecations.md
+---
+```
+
+Only a single source file could be linked, which is useless if a document refers
+to multiple files (or multiple sections within a single file). A more flexible
+approach is to use the new [icon integration][3]:
+
+``` markdown
+[:octicons-file-code-24: Source](https://github.com/squidfunk/mkdocs-material/blob/master/docs/deprecations.md)
+```
+
+This will render as:
+
+[:octicons-file-code-24: Source][4]

-### Linking sources
 
-When a document is related to a specific source file and the `repo_url` is
-defined inside the project's `mkdocs.yml`, the file can be linked using the
-`source` key:
-
-``` markdown
-source: file.js
-```
-
-The filename is appended to the `repo_url` set in `mkdocs.yml`, but can be
-prefixed with a `path` to ensure correct path resolving. The name of the source
-file is shown in the tooltip.
-
-Example:
-
-``` markdown
-path: tree/master/docs/extensions
-source: metadata.md
-```
-
-### Redirecting to another page
-
-It's sometimes necessary to move documents around in the navigation tree and
-redirect users from the old URL to the new one. The `redirect` meta-tag allows
-to create a redirection from the current document to the address specified in
-the tag.
-
-For instance, if your document contains:
-
-``` markdown
-redirect: /new/url
-```
 
 accessing that document's URL will automatically redirect to `/new/url`.
