 Inheriting from `str` had upsides and downsides, and for V2 we decided it would be better to remove this. To use these
 types in APIs which expect `str` you'll now need to convert them (with `str(url)`).
 
+### Constrained types
+
+The `Constrained*` classes were _removed_, and you should replace them by `Annotated[<type>, Field(...)]`, for example:
+
+```py
+from pydantic import BaseModel, ConstrainedInt
+
+
+class MyInt(ConstrainedInt):
+    ge = 0
+
+
+class Model(BaseModel):
+    x: MyInt
+```
+
+...becomes:
+
+```py
+from pydantic import BaseModel, Field
+
+
+class Model(BaseModel):
+    x: Annotated[int, Field(ge=0)]
+```
+
+Read more about it on the [Composing types via `Annotated`](../usage/types/custom/#composing-types-via-annotated) section.
+
+For `ConstrainedStr` you can use [`StringConstraints`][pydantic.types.StringConstraints] instead.
