 * refactor: Remove unused code & use constants whenever possible for builtin instance definitions[#1707](https://github.com/lambdaclass/cairo-vm/pull/1707)
 
+* feat: missing EC hints for Starknet OS 0.13.1 [#1706](https://github.com/lambdaclass/cairo-vm/pull/1706)
+
 * fix(BREAKING): Use program builtins in `initialize_main_entrypoint` & `read_return_values`[#1703](https://github.com/lambdaclass/cairo-vm/pull/1703)
   * `initialize_main_entrypoint` now iterates over the program builtins when building the stack & inserts 0 for any missing builtin
   * `read_return_values` now only computes the final stack of the builtins in the program
