v1.3.0

Added

• Asyncio Support - New erlang.async_call() for asyncio-compatible callbacks
  • await erlang.async_call('func', arg1, arg2) - Call Erlang from async Python code
  • Integrates with asyncio event loop via add_reader()
  • No exceptions raised for control flow (unlike erlang.call())
  • Releases dirty NIF thread while waiting (non-blocking)
  • Works with FastAPI, Starlette, aiohttp, and other ASGI frameworks
  • Supports concurrent calls via asyncio.gather()

Fixed

• Flag-based callback detection in replay path - Fixed SuspensionRequired exceptions leaking when ASGI middleware catches and re-raises exceptions

Changed

• C code optimizations and refactoring
  • Thread safety fixes: Used pthread_once for async callback initialization
  • Timeout handling: Added read_with_timeout() and read_length_prefixed_data() helpers
  • Code deduplication: Merged suspended state creation functions, extracted helpers
  • Performance: Optimized list conversion using enif_make_list_cell()
