AReaL 2026 Q1 Milestone Tracker

Introduction

This document tracks major planned enhancements for AReaL through April 30, 2026. Our development roadmap is organized into two categories to help contributors identify where they can make the most impact:

On-going sections contain features currently under active development by the core AReaL team. These represent our immediate priorities.

Planned but not in progress sections list features with concrete implementation plans that we currently lack bandwidth to pursue. We actively welcome community contributions for these items! If you're interested in contributing to any planned feature, please reach out to discuss implementation details.
