## 📋 Licensing Resolution

### The Issue (Before)
```
Copyright (c) 2025 Alex Shovkoplyas
```
This was incorrect because Alex is the author of DVOACAP (the source), not this Python port.

### The Solution (After)
```
MIT License

Copyright (c) 2025 Joel Morin and Contributors

This software is based on DVOACAP by Alex Shovkoplyas (VE3NEA)
https://github.com/VE3NEA/DVOACAP
Copyright (c) 2025 Alex Shovkoplyas

DVOACAP is based on VOACAP algorithms developed by Voice of America
and the Institute for Telecommunication Sciences (ITS).
Original VOACAP software is in the public domain.
```

### Why MIT License is Correct ✅

1. **DVOACAP was relicensed** from MPL 1.1 to MIT in May 2025 by Alex Shovkoplyas
2. **dvoacap-python was created** in November 2025 AFTER the relicensing
3. **MIT permits derivative works** under any license
4. **Proper attribution** maintained throughout (VOACAP → DVOACAP → dvoacap-python)

### Files Created

- **NOTICE** - Complete attribution chain and development history
- **LICENSE_NOTE.txt** - Explains old MPL headers in Pascal reference files
- **RELEASE_NOTES_v1.0.0.md** - Comprehensive release documentation

## ⚠️ Note About Git Tag

The git tag `v1.0.0` was created successfully but encountered a 403 error when pushing to remote. The tag exists locally and can be pushed:

```bash
# Option 1: Push tag manually
git push origin v1.0.0

# Option 2: Create tag through GitHub UI
# Go to Releases → Draft a new release → Select/create tag v1.0.0
```

This is a minor issue and doesn't affect the release. The tag can be pushed later or created through the GitHub interface when creating the release.
