v1.0.2 - Live Gameplay Automation and Capture

Blueprint Automation Toolkit 1.0.2

Version 1.0.2 adds a native, Python-free workflow for testing live gameplay
and collecting reproducible showcase evidence from Unreal Editor.

Highlights

• Added managed live capture sessions with start, status, and stop endpoints.
• Added real-tick PIE frame capture as PNG sequences and native Unreal Engine
  MP4 recording without FFmpeg or external processes.
• Added typed PIE keyboard input for press, release, and tap actions.
• Added runtime assertions for actor existence, actor counts, and reflected
  property values in editor or PIE worlds.
• Added structured capture manifests, progress reporting, dropped-frame
  accounting, safe output paths, duration limits, and lifecycle cleanup.
• Added multi-PIE selection for PNG capture and explicit primary-PIE handling
  for Unreal Engine's native MP4 recorder.
• Extended route discovery, authorization policies, OpenAPI documentation,
  automated tests, and advanced prompt examples.

Compatibility

• Unreal Engine 5.5, 5.6, 5.7, and 5.8
• Windows 64-bit Unreal Editor
• Editor-only; the plugin is not included in packaged games

Validation

• Fab-style BuildPlugin packaging completed successfully on UE 5.5, 5.6,
  5.7, and 5.8.
• All three focused live-automation tests passed on UE 5.8.
• The OpenAPI contract parsed successfully with all six new live-automation
  routes present.

Each Fab archive is engine-specific, sets the matching EngineVersion and
Installed=true, and includes precompiled Win64 editor binaries plus source,
configuration, content, documentation, resources, and the MIT license.

v1.0.1 - Asset Pipeline and Spline Mesh Support

Blueprint Automation Toolkit 1.0.1

Version 1.0.1 expands BAT's asset and Blueprint automation surface while
preserving its editor-only, localhost-only security model.

Highlights

• Added a source-asset pipeline for import, inspection, configuration,
  validation, repair, asynchronous execution, rollback, and editor evidence
  capture.
• Added Fab-oriented validation profiles and structured diagnostics for
  automated marketplace-readiness checks.
• Added SplineMeshComponent support to Blueprint component automation,
  including creation, mutation, and component replacement.
• Added explicit spline mesh start/end positions and tangents, plus local-space
  sampling from an existing SplineComponent.
• Extended schema discovery, OpenAPI documentation, advanced prompt examples,
  and verified Codex workflow evidence.

Compatibility

• Unreal Engine 5.5, 5.6, 5.7, and 5.8
• Windows 64-bit Unreal Editor
• Editor-only; the plugin is not included in packaged games

Validation

• UE 5.5, 5.6, and 5.8 BuildPlugin packaging completed successfully.
• UE 5.7 completed an isolated Development Editor build with the required
  engine dependencies.
• Focused Blueprint automation tests passed on UE 5.5.
• Focused OpenAPI contract tests passed on UE 5.5.

The Fab archives are engine-specific precompiled Win64 packages. Each archive
includes an EngineVersion value matching its supported Unreal Engine release,
sets Installed to true, and contains the corresponding editor binaries,
source, configuration, content, documentation, resources, and license.
Generated Intermediate, Build, and Saved directories are excluded.
