 ### Bug fixes

-  in corrupt table mappings to be created.
+- Reject the `PAGE_OR_TABLE` flag when passed to `map_range`, which would result in corrupt table
+  mappings to be created.
 
 ### Breaking changes
 
-- Updated `modify_range` to split block entries before traversing them, and
-  pass only the descriptors and subregions that are completely covered by the
-  given region to the updater callback function.
-- Updated `modify_range` to only pass block or page descriptors to the callback
-  function and prevent them from being converted into table descriptors
-  inadvertently.

 ### New features
 
 - Added new `map_range()` alternative `map_range_with_constraints()` with extra `contraints`
   argument.
-- Added `walk_range` method that iterates over all block or page descriptors
-  that intersect with a given region, without permitting the callback to make
-  changes to the descriptors
