# 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](https://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

<Note>
  Initial early access release of the RotaStellar API.
</Note>

### Available

* **Planning Tools API** — Feasibility analysis, thermal modeling, latency simulation, power budgeting
* **Orbital Intelligence API** — Satellite tracking, conjunction analysis, pattern detection
* **Python SDK** — `pip install rotastellar`
* **Node.js SDK** — `npm install @rotastellar/sdk`
* **Rust SDK** — `cargo add rotastellar`

### Coming Soon
