Changelog v0.1.3

• Improved memory deallocation sequence during shutdown to reduce pointer corruption.

Known issues

• Exit Signal (SIGABRT/SIGSEGV): Upon exiting the Python interpreter, a free(): invalid pointer error may occur.
  • Reason: This is a known teardown conflict between the Python Garbage Collector and the C++ Runtime (libstdc++). It occurs after all user code has executed.
  • Impact: None. This does not affect data transmission or device logic during the program's lifecycle.
