Support

Where to Go

• Bug reports: Open a GitHub issue with a minimal reproduction
• Performance questions: Open an issue and include hardware, compiler, and benchmark context
• Feature ideas: Open an issue for discussion, even though feature PRs are not currently accepted
• Security issues: Follow SECURITY.md and report privately by email

What to Include

For build, runtime, or performance issues, include:

• Operating system
• Compiler and version
• CMake version
• Build type (Release, RelWithDebInfo, or Debug)
• Enabled NexusFIX options such as NFX_ENABLE_SIMD, NFX_ENABLE_ABSEIL, and NFX_ENABLE_IO_URING
• Minimal FIX message, code sample, or benchmark command that reproduces the issue
• Exact compiler output, test failure, or sanitizer report

Response Expectations

• Best-effort support for the latest public release
• Older releases may receive limited guidance
• Security reports are handled through coordinated disclosure, not public issues
