 * feat: Add HintProcessor::execute_hint_extensive + refactor hint_ranges [#1491](https://github.com/lambdaclass/cairo-vm/pull/1491)
 
+  * Add trait method `HintProcessorLogic::execute_hint_extensive`:
+    * This method has a similar behaviour to `HintProcessorLogic::execute_hint` but it also returns a `HintExtension` (type alias for `HashMap<Relocatable, Vec<Box<dyn Any>>>`) that can be used to extend the current map of hints used by the VM. This behaviour achieves what the `vm_load_data` primitive does for cairo-lang, and is needed to implement os hints.
+    * This method is now used by the VM to execute hints instead of `execute_hint`, but it's default implementation calls `execute_hint`, so current implementors of the `HintProcessor` trait won't notice any change.
+
   * Signature changes:
     * `pub fn step_hint(&mut self, hint_executor: &mut dyn HintProcessor, exec_scopes: &mut ExecutionScopes, hint_datas: &mut Vec<Box<dyn Any>>, constants: &HashMap<String, Felt252>) -> Result<(), VirtualMachineError>` -> `pub fn step_hint(&mut self, hint_processor: &mut dyn HintProcessor, exec_scopes: &mut ExecutionScopes, hint_datas: &mut Vec<Box<dyn Any>>, hint_ranges: &mut HashMap<Relocatable, HintRange>, constants: &HashMap<String, Felt252>) -> Result<(), VirtualMachineError>`
     * `pub fn step(&mut self, hint_executor: &mut dyn HintProcessor, exec_scopes: &mut ExecutionScopes, hint_data: &[Box<dyn Any>], constants: &HashMap<String, Felt252>) -> Result<(), VirtualMachineError>` -> `pub fn step(&mut self, hint_processor: &mut dyn HintProcessor, exec_scopes: &mut ExecutionScopes, hint_datas: &mut Vec<Box<dyn Any>>, hint_ranges: &mut HashMap<Relocatable, HintRange>, constants: &HashMap<String, Felt252>) -> Result<(), VirtualMachineError>`
