Version 2.0.0​

🚀 Major Version Release

We're excited to announce a major update of the library — now supporting both Aria Gen1 and Gen2 VRS data with the same C++ and Python APIs you already know. This release also introduces full access to On-Device Machine Perception (MP) data in Aria Gen2 VRS.

API & Data Compatibility​

  • Unified Interface: The C++ and Python APIs remain unchanged — your existing Gen1 code continues to work seamlessly
  • Extended Capabilities: Added APIs to access On-Device Machine Perception data streams available in Gen2 recordings
  • Cross-Generation Support: A single codebase now handles Gen1 and Gen2 VRS data without modification

New & Enhanced Tools​

New Tools​

  • aria_rerun_viewer: A Python-based visualizer for Aria VRS files, built on Rerun for interactive multi-modal exploration
  • gen2_mp_csv_exporter: A Python tool to export On-Device MP data from VRS to CSV, fully compatible with the Machine Perception Service (MPS) format

Upgraded Tools​

  • vrs_health_check: Completely re-engineered and released as a standalone Python package for easier installation & use

Documentation​

  • New Python Tutorials: Our Python tutorials have been completely rewritten into seven focused guides, covering topics such as:
    • Queued multi-sensor data
    • Device calibration usage
    • Multi-device time alignment
    • ...and more
  • Updated Documentation Websites: We now maintain dedicated documentation portals for each generation:
    • Aria Gen2 Documentation Website — new APIs, tools, and data formats
    • Aria Gen1 Documentation Website — original docs for Gen1 workflows
