This release makes PixLog straightforward to discover, install, and try while keeping its Git-native architecture unchanged.

What’s New

  • The versioned PixLog Visual Policy composite Action for pull requests.
  • Canonical Go module path github.com/zhao-xuan/PixLog, enabling standard remote go install commands.
  • Reproducible README stills, demo recordings, and a 1280x640 social preview.

Known Limitations

  • Built-in pixel decoding currently covers PNG, JPEG, and GIF. Other recognized formats retain exact-byte history and provenance but may not have visual diff.
  • Photoshop and browser adapters still require host packaging and validation.
  • There is no hosted collaboration service, HTTP lock service, or Web review UI.
  • Hosted-model recipes may be provenance-only and are not claimed to reproduce deterministically when parameters are unavailable.
