Notes

• Tag: 1.0.0-alpha.6
• Target branch: main (head)
• This file is a draft; publish via GitHub Releases when ready.

What's New

• Consolidated and fixed numerous compiler and format warnings across the codebase, improving build hygiene and reducing noisy diagnostics.
• Windows build and console improvements: better console type detection, safer line-mode handling, and fixes to Windows IOCP integration.
• New lib/async library and integration: unified async worker/runtime, async_worker integration with port_event_t, and added timer flags to improve cross-platform I/O and worker coordination.
• Console automation and testing: added a console testbot (using pexpect), improved piped-stdin support, and fixed related unit tests for console workers.
• Stability and memory fixes: fixed leaked shared strings, ensured proper object destruction during teardown, and cleaned up permanent identifier and IP entry memory handling.
• Documentation updates: added design docs for lib/async and cleaned up set_eval_limit docs.

These changes collectively improve cross-platform reliability (especially Windows), reduce runtime leaks, and make developing and testing the driver easier.
