Changelog

v5.0.0-rc2 — 2026-07-15

Changed

• License: MIT → Apache 2.0 (explicit patent grant for engineering users)
• Repository: Professional README with badges, architecture, features, and screenshots section
• CI/CD: Expanded to 4 workflows (lint, test, docs, package) across Python 3.10–3.12
• Issue templates: Added validation, documentation, and plugin submission templates
• PR template: Expanded with motivation, testing, documentation, and validation checkboxes

Added

• Engineering transparency doc: Assumptions, limitations, intended/non-intended use, numerical methods, liability disclaimer
• Full documentation structure: 8 doc directories (user, developer, api, theory, validation, architecture, manufacturing, tutorials) with index files
• Release notes: RELEASE_NOTES.md in repository root
• CODEOWNERS: Fine-grained ownership for core modules
• Assets placeholder: assets/README.md for future screenshots
• Package verification workflow: GitHub Action on version tags
• 8 integration tests: Project model, dependency tracking, RVM, vehicle assembly, database, collaboration, design reviews, simulation runner

Fixed

• Dependency tracking: propulsion.set() now correctly marks performance.dirty (fixed _to_sub function)
• pyproject.toml: Optional-dependencies syntax fixed (inline table → proper section)
• pyproject.toml: Added classifiers, improved metadata, Apache-2.0 license field

v5.0.0-rc1 — 2026-07-15

Added

• 7 engineering workspaces (Design, Analysis, Engineering, Operations, Learning, Project, Admin) with 28 tabs
• Central Project data model with dependency tracking
• Validation dashboard comparing against 4 Phoenix flight datasets
• Requirements Verification Matrix (RVM) with auto-check against Project
• Design Review workspace: SRR → PDR → CDR → FRR
• Engineering Database (9 materials, 3 component categories)
• Plugin framework with discovery, validation, and installation
• Background simulation runner (QThread job queue)
• AI Copilot abstraction (OpenAI/Anthropic/Gemini)
• Learning Center (beginner/intermediate/advanced paths)
• Collaboration (review comments, change requests, approvals)
• Manufacturing package (BOM, part numbers, fastener schedule)
• Parametric CAD export (SVG, DXF, STEP)
• Engineering specifications (auto-generated spec sheets for all subsystems)
• 15 unit tests for core physics modules (all passing)

Fixed

• ISA atmosphere now valid to 86 km (previously broke above 44 km)
• Regression coefficients corrected to m/s units (previously 1000x too high)
• Rail direction corrected from horizontal to vertical angle (3-DOF/6-DOF)

Known limitations

• Single calibrated reference case (Phoenix-1B); validation dashboard flags other variants as REVIEW
• AI Copilot requires user-set API keys; offline-capable
• No installer scripts yet — manual pip install
