Critical Issues

This is a straightforward patch version bump of the Polyfill dependency used for compile-time type generation on older frameworks (netstandard2.0, netstandard2.1, and .NET Framework). The change:

• ✅ Only touches the version constant in TUnit.Core.targets
• ✅ No source generator or engine changes (dual-mode rule N/A)
• ✅ No snapshot test updates needed (rule N/A)
• ✅ No public API changes (rule N/A)
• ✅ No VSTest dependencies (rule compliant)
• ✅ No performance-critical path changes (rule N/A)
• ✅ No reflection or AOT concerns (rule N/A)

Patch version updates like this are typically safe and contain only bug fixes.

Verdict

✅ APPROVE - No critical issues
