Version history and release notes for the Vantrexia RPM platform. All notable changes are documented here following Semantic Versioning (SemVer) — where MAJOR versions introduce breaking changes, MINOR versions add backwards-compatible features, and PATCH versions include backwards-compatible bug fixes.

# Version 1.0.0 Current

The initial public release of the Vantrexia Remote Patient Monitoring platform — a full-featured, HIPAA-compliant RPM solution with eClinicalWorks integration, automated billing, real-time triage, and multi-practice support.

New Features

  • Full eClinicalWorks FHIR R4 integration — bidirectional sync of patients, practitioners, and clinical observations with eCW via standards-compliant FHIR APIs
  • MioConnect device gateway — cellular-connected hub support for automatic collection of blood pressure, SpO2, weight, and glucose readings without requiring patient Wi-Fi
  • Exception-based triage engine — automated, rule-driven patient prioritization with configurable thresholds, color-coded severity levels, and escalation workflows
  • CPT billing automation — full support for RPM billing codes 99453 (device setup), 99454 (monthly supply/transmission), 99457 (first 20 min monitoring), and 99458 (additional 20 min)
  • Multi-practice support — isolated practice environments with independent patient rosters, provider teams, billing configs, and triage rules on a shared platform instance
  • Real-time dashboard — comprehensive provider dashboard with patient health cards, vital sign trends, adherence tracking, billing eligibility, and KPI widgets
  • Push notifications (FCM) — real-time mobile alerts for critical vital readings, triage escalations, device disconnections, and billing milestones via Firebase Cloud Messaging
  • HIPAA-compliant audit logging — comprehensive audit trail tracking all data access, modifications, authentication events, and administrative actions with 7-year retention
  • Patient archival system — soft-delete patient archival with full data retention for compliance, supporting restore and permanent purge workflows
  • Automated billing reports — scheduled and on-demand billing report generation with CMS-1500 compatible output, exportable in CSV and PDF formats

API

  • 150+ REST endpoints — comprehensive API coverage for patients, observations, devices, billing, triage, practices, users, audit logs, and system configuration
  • JWT authentication with refresh tokens — secure authentication using short-lived access tokens (15 min) and refresh tokens (1 day) with automatic rotation
  • Rate limiting — configurable per-endpoint rate limiting defaulting to 100 requests/minute per authenticated user, with higher limits for service accounts
  • Pagination (cursor-based) — efficient cursor-based pagination across all list endpoints, supporting configurable page sizes and consistent ordering
  • OpenAPI 3.0 documentation — auto-generated, interactive API documentation with request/response schemas, authentication details, and example payloads

Infrastructure

  • Docker Compose deployment — single-command deployment of all platform services (backend, frontend, workers, database, cache, reverse proxy) via Docker Compose
  • GitHub Actions CI/CD — automated build, test, and deployment pipeline with multi-architecture Docker image builds, security scanning, and staged rollouts
  • Zero-downtime deploys — rolling deployment strategy with health checks ensuring continuous availability during updates with automatic rollback on failure
  • PostgreSQL 15 + Redis 7 — production-grade data infrastructure with PostgreSQL for persistent storage and Redis for caching, task queuing, and session management
  • Celery task queue — distributed async task processing for notifications, billing calculations, data sync, report generation, and scheduled maintenance jobs
  • Nginx reverse proxy with SSL — TLS 1.2+ termination, static file serving, request buffering, rate limiting, and security headers via Nginx

Security

  • AES-256 field-level encryption — all PHI fields encrypted at rest using AES-256 with per-field encryption keys managed through a secure key hierarchy
  • TLS 1.2+ — enforced transport layer encryption for all API communications, inter-service traffic, and database connections
  • RBAC (7 roles) — granular role-based access control with seven predefined roles (admin, clinical_manager, provider, nurse, ma, data_monitor, patient), each with a specific set of API-level permissions
  • Account lockout protection — automatic account lockout after 5 consecutive failed login attempts with configurable duration and admin override capability
  • Comprehensive audit trail (7-year retention) — immutable, tamper-evident audit logs covering all system events, compliant with HIPAA's minimum 6-year retention requirement

# Version 1.1.0 Upcoming

Planned Features

The following features are planned for the v1.1.0 release. Timelines and scope are subject to change based on development priorities and customer feedback.

  • Epic EMR integration — FHIR R4-based integration with Epic Systems for patient data synchronization, supporting the same bidirectional workflows available for eClinicalWorks
  • Medication adherence tracking — new module for tracking patient medication compliance alongside vital signs, with configurable reminders and provider alerts for missed doses
  • Patient mobile app (iOS/Android) — native mobile application for patients to view their own readings, receive medication reminders, communicate with care teams, and manage their profile
  • Advanced analytics dashboard — enhanced reporting with population health analytics, predictive risk scoring, provider performance metrics, and exportable BI-ready datasets
  • Automated compliance reporting — scheduled generation of HIPAA compliance reports, access reviews, and security posture assessments with one-click audit readiness packages
  • Webhook event subscriptions — configurable webhook endpoints for real-time event notifications (new observations, triage alerts, billing events, device status changes) enabling custom integrations
