How Updates Work

1. The application checks GitHub releases for newer versions
2. If a newer version is found, it downloads the appropriate binary for the current platform
3. SHA256 checksums are verified for integrity
4. The old binary is replaced with the new one

CI/CD

The project uses GitHub Actions for automated releases:

• On push to main branch, a new release is created
• Binaries are built for Linux and Windows
• SHA256 checksums are generated and included
• Release notes are automatically generated

Dependencies

• go-selfupdate - Self-updating library
