SwirEngine 2.2.0

SwirEngine 2.2.0 Release Notes

Prepared from the bound 2.2.0 candidate. Public availability is authoritative only from the
immutable v2.2.0 tag, GitHub Release metadata and PyPI project metadata.

Production tools and visual creation

• Deterministic material and shader assets with creator-facing editing and shipping-renderer
  preview paths.
• Visual node-graph authoring that keeps untrusted graph data separate from trusted Python
  execution.
• Terrain, foliage, animation state-machine and blend-tree authoring backed by runtime data.
• Particle/VFX, lighting, environment and post-processing authoring with isolated previews and
  project-confined resources.
• Responsive UI Designer workflows with reusable styles, interaction states and bounded
  animations over the shipping UI toolkit.
• Privacy-safe multiplayer diagnostics and a capability-gated Editor Extension SDK.

Compatibility and qualification

• Preserves the published SwirEngine 2.1 project/runtime compatibility baseline.
• Supports the maintained 64-bit CPython 3.10–3.14 matrix on the explicitly tested Windows,
  Linux and macOS runners.
• Keeps public API compatibility, source/runtime version parity, deterministic package contents,
  clean-wheel installation and representative 2D, 3D and multiplayer projects under release
  gates.
• Excludes repository-only release evidence and publication-control markers from wheel and sdist
  payloads.

Release identity

The guarded publication workflow binds the reviewed candidate source, required-workflow manifest,
publication marker chain, v2.2.0 tag, PyPI files, checksums, provenance and GitHub Release assets.
Existing public objects are immutable; retry/resume may add only objects proven to be missing.
