Breaking Changes

●Issue #1

The @staticmethod decorator was removed from the module-level function get_device_and_memory_breakdown, which may cause errors if code was attempting to access it as a static method of a class or via an incorrect namespace.

Migration Steps

  1. 1
    Ensure calls to get_device_and_memory_breakdown are treated as standard module-level function calls rather than static methods.

Release Summary

This patch release focuses on fixing Mistral tokenizer mappings and Tekken pattern matching, while also correcting a decorator error in the device memory utility.
