feat(config)!: add new option constraintsFiltering

docs/usage/configuration-options.md

@@ -525,6 +525,19 @@ If you need to _override_ constraints that Renovate detects from the repository,
 !!! note
     Make sure not to mix this up with the term `compatibility`, which Renovate uses in the context of version releases, e.g. if a Docker image is `node:12.16.0-alpine` then the `-alpine` suffix represents `compatibility`.
 
+## constraintsFiltering
+
+This option controls whether Renovate filters new releases based on configured or detected `constraints`.
+Renovate supports two options:
+
+- `none`: No release filtering (all releases allowed)
+- `strict`: If the release's constraints match the package file constraints, then it's included
+
+We are working on adding more advanced filtering options.
+
+Note: There must be a `constraints` object in your Renovate config for this to work.
+This feature is limited to `pypi` datasource only.
+
 ## defaultRegistryUrls
 
 Override a datasource's default registries with this config option.
