 #### Upcoming Changes
 
+* fix: Fixed deserialization issue when signature additional data is empty, and the name of the builtin range_check96 [#1785](https://github.com/lambdaclass/cairo-vm/pull/1785)
+
 * refactor + bugfix: Improve arg handling for cairo1-run [#1782](https://github.com/lambdaclass/cairo-vm/pull/1782)
   * Now uses ascii whitespace as separator, preventing errors when using newlines in args file
   * No longer gets stuck on improperly-formatted arrays
