 # Changelog
 
-### 0.1.0 - TODO
+### 0.5.0 - First public version
 
-TODO
+ * Validate both type and value with `isinstance`, thanks to easy-to-write "validating types"
+ * `has_valid_type` and `has_valid_value` methods provided for easy auditing, as well as `is_vtype`
+ * Validation syntax fully compliant with `valid8`. Compliant error message available through a `validate()` method
+ * v-types are composable so that creating a library of reusable elements is straightforward (note: should we provide one in this library based on `valid8` [library](https://smarie.github.io/python-valid8/validation_funcs/b_base_validation_lib/) ?)  
+ * Two styles: `vtype(...)` constructor method, as well as an alternate `class ...(VType)` style to perform composition using inheritance, and write docstrings more easily.
