FixedMathSharp v2.1.0

This release focuses on serialization cleanup and compatibility rather than numeric behavior changes.

Refactor

• Improved serialization support across core numerics and bounds types, including Fixed64, vectors, matrices, quaternions, ranges, curves, BoundingArea, BoundingBox, and BoundingSphere.
• Added explicit System.Text.Json metadata so JSON round-trips no longer depend on IncludeFields or IgnoreReadOnlyProperties.
• Added non-.NET 8 JSON attribute shims to keep serialization annotations working across older target frameworks.
• Simplified BoundingBox serialization to a state-based payload using Min and Max, removing the old versioned serialization field.
• Expanded JSON and MemoryPack round-trip test coverage for the affected types.
• Added .editorconfig and normalized formatting across the touched files.

Migration Note

If you relied on BoundingBox’s old (min, max, version) constructor or serialized Version field, update to the new state-based contract.

FixedMathSharp v2.0.0

Breaking changes

• Dropped .NET Framework 4.8 support.
• Added/standardized support on netstandard2.1 (with net8 retained).
• Serialization stack changed from MessagePack to MemoryPack.

Updated tooling/runtime settings

• C# language version bumped to 11.0.
• Test project modernized:
  • moved to net8
  • updated test SDK/packages (including xUnit v3-related packages and newer test tooling).

Internal/maintenance

• Added basic AGENTS.md.
• Minor hash code implementation cleanup in core numeric structs (no API expansion, but behavior may differ for hash-based scenarios).

What's Changed

• develop to main by @mrdav30 in #44

Full Changelog: v1.3.4...2.0.0

FixedMathSharp v1.3.4

• BugFix
  • refactored BoundingBox to use a canonical min/max representation internally
    • removes dual-state risk of tracking scope and size separately

FixedMathSharp v1.3.3

• New Features
  • Added new DeterministicRandom struct.
    • Switched to using xoroshiro128++ with splitmix64 seeding to ensure no allocations, no time/GUID.
• Notice
  • Marked ThreadLocalRandom obsolete
    • DeterministicRandom gives explicit, reproducible streams keyed to your world/feature, independent of threading.

FixedMathSharp v1.3.2

• BugFix
  • Updated intersection logic to correctly detect intersections between flat (zero-thickness) BoundingAreas in any primary plane.
    • Previously, coplanar and edge-touching areas were not recognized as intersecting due to 3D AABB logic.
    • Now uses 2D overlap checks when both bounds are flat in the same axis.

Full Changelog: v1.3.1...v1.3.2

FixedMathSharp v1.3.1

• New Features
  • Added serialization support for MessagePack-CSharp
• Refactors
  • Added serialization to IBound structs
• Documentation
  • Added CONTRIBUTING

FixedMathSharp v1.3.0

• New Features

  • Generic Clamp Utility
    • Added Clamp(T value, T min, T max) for general-purpose clamping across comparable types (fills a missing gap in .NET 4.8).

• Refactors

  • Fixed64 Clamp Overload Updated
    • Removed nullable max overload to avoid ambiguity with new generic version.
    • Replaced with Clamp(Fixed64 value, Fixed64 min, Fixed64 max) for explicit and more performant clamping.

FixedMathSharp v1.2.3

• Expanded Vector2d, Vector3d & Fixed64 operators
• Fixed issue with Vector3d.ClampMagnitude
• Added indexer for Fixed3x3 & Fixed4x4
• Added zeroed out FixedQuaternion & Fixed4x4

FixedMathSharp v1.2.2

• Improved Trigonometric Functions – Enhanced Sin precision and and in turn Cos.
• Better Quaternion & Vector Normalization – Fixed rounding errors and ensured proper unit magnitudes.
• Added Helper Methods – Streamlined common math operations for better performance and maintainability.
