Changelog

All notable changes to the RotaStellar API.

​
2026-03-05 — CAE v1.0

​
New: Constraint-Aware Execution

  • CAE API — POST a workload + satellite ID, get a physically-accurate execution plan computed from real orbital mechanics
  • 5 built-in presets: on-board ML inference, split learning, earth observation with QA, federated learning, resilient store-and-forward
  • Custom workload DAGs — define arbitrary step pipelines with dependencies, resource requirements, and security policies
  • 4-phase planner: topological sort, compute placement, transfer insertion, window scheduling
  • Real orbital mechanics: SGP4 propagation, eclipse detection, 12-station ground network (KSAT, NASA, AWS)
  • Simulated execution events: full event stream with transfer, checkpoint, and security events

​
2026-02-01 — SDK Updates & Documentation Improvements

​
SDK Updates

  • Python SDK v0.2.0 — Fixed Position type to use latitude/longitude fields consistently
  • Node.js SDK v0.2.0 — Aligned field names with Python SDK (latitude, longitude, altitudeKm)
  • Rust SDK v0.1.1 — Types-only release with Position, Orbit, Satellite, TimeRange structs

​
API Improvements

  • Trajectory API — Now accepts ISO 8601 strings for start and end parameters
  • Patterns API — Added type filter parameter for filtering by pattern type (maneuver, anomaly, proximity)
  • Conjunctions API — Response now includes miss_distance_km and collision_probability fields

​
Documentation

  • Updated all SDK examples to use correct RotaStellarClient class name
  • Fixed code examples across 20+ documentation pages
  • Added comprehensive error handling examples

​
2026-01-28 — Dashboard Beta & Distributed Compute Preview

​
New Features

  • Dashboard Beta — Web-based dashboard for satellite tracking and conjunction monitoring at app.rotastellar.com
    • Real-time satellite position visualization
    • Conjunction risk timeline
    • API usage metrics
  • Distributed Compute SDK Preview — rotastellar-distributed package now available
    • FederatedClient for gradient compression and federated learning
    • CompressionConfig with TopK + quantization (100x compression)
    • Python: pip install rotastellar-distributed
    • Node.js: npm install @rotastellar/distributed

​
API Updates

  • List Satellites — Added constellation and operator filter parameters
  • Get Satellite — Response now includes orbit object with computed properties
  • Rate Limits — Increased Pro tier limits to 100 req/min

​
2026-01-24 — Intelligence API Enhancements

​
New Endpoints

  • GET /v1/satellites/{id}/trajectory — Get predicted positions over a time range
  • GET /v1/patterns — Detect maneuvers, anomalies, and proximity operations
  • POST /v1/conjunctions/watch — Set up webhook alerts for conjunction events

​
Improvements

  • Conjunction Analysis — Now includes avoidance maneuver recommendations
  • Pattern Detection — Added confidence scores and detailed descriptions
  • Satellite Metadata — Enhanced with operator, constellation, and launch date fields

​
2026-01-21 — Early Access Launch

Initial early access release of the RotaStellar API.
