 modrinth-featured: true
 ```
 
+#### modrinth-unfeature-mode
+
+Determines the way automatic unfeaturing of older Modrinth versions works. Default value is `subset`, if [`modrinth-featured`](#user-content-modrinth-featured) is set to true; otherwise, `none`.
+
+```yaml
+modrinth-unfeature-mode: version-intersection | loader-subset
+```
+
+Available presets:
+
+ - `none` - no Modrinth versions will be unfeatured
+ - `subset` - only those Modrinth versions which are considered a subset of the new one *(i.e., new release suports all of the version's mod loaders **and** game versions)* will be unfeatured
+ - `intersection` - only those Modrinth versions which intersects with the new one *(i.e., support at least one of the mod loaders and one of the game versions supported by the new release)* will be unfeatured
+ - `any` - all Modrinth versions will be unfeatured
+
+ If none of the given presets suits your needs, you can construct a new one from the following values via bitwise `OR`, like so - `version-intersection | loaders-subset`:
+
+ - `version-subset`
+ - `version-intersection`
+ - `version-any`
+ - `loader-subset`
+ - `loader-intersection`
+ - `loader-any`
+
