Add v0.2 release notes for GTC. (#485)

## Summary
Add a draft version of the v0.2 release notes.

## Detailed description
- Adding a draft of these release notes such that people landing `main`
can read the release notes.
- Note that these are a draft (as indicated in the notes) as `v0.2` is
not yet released.

 Release Notes
 =============
 
+Unreleased: v0.2.0
+------------------
+
+This release of Isaac Lab-Arena focuses on adding essential features needed for creation and
+execution of large-scale task libraries with complex long-horizon tasks.
+
+.. note::
+
+  Changes on ``main`` contains an in development version of v0.2.0.
+  As of March 16th 2026 (GTC San Jose 2026), ``main`` contains most of the features for the v0.2.0 release,
+  however, is based on Isaac Lab 2.3 (rather than Isaac Lab 3.0) and has not been SQA tested.*
+
+**Key Features**
+
+- **LEGO-like Composable Environments** — Mix and match scenes,  embodiments, and tasks independently
+- **On-the-fly Assembly** — Environments are built at runtime; no duplicate config files to maintain.
+- **New Sequential Task Chaining** — Chain atomic skills (e.g. Pick + Walk + Place + …) to create complex long-horizon tasks.
+- **New Natural Language Object Placement** — Define scene layouts using semantic relationships
+  like "on" or "next to", instead of manually specified coordinates.
+- **Integrated Evaluation** — Extensible metrics and evaluation pipelines for policy benchmarking
+- **New Large-scale Parallel Evaluations with Heterogeneous Objects** — Evaluate policy on multiple parallel
+  environments, each with different objects, to maximize evaluation throughput.
+- **New RL Workflow Support and Seamless Interoperation with Isaac Lab** — Plug Isaac Lab-Arena environments
+  into Isaac Lab workflows for Reinforcement learning and Data generation for imitation learning.
+
+
+**Ecosystem**
+NVIDIA and partners are building Industrial and academic benchmarks on the unified Isaac Lab-Arena core,
+so you can reuse LEGO blocks (tasks, scenes, metrics, and datasets) for your custom evaluations.
+
+- `Lightwheel RoboFinals <https://lightwheel.ai/robofinals>`_ — high fidelity industrial benchmarks
+- `Lightwheel RoboCasa Tasks <https://github.com/LightwheelAI/LW-BenchHub>`_ — 138+ open-source tasks,
+  50 datasets per task, 7+ robots
+- `Lightwheel LIBERO Tasks <https://github.com/LightwheelAI/LW-BenchHub>`_ — Adapted LIBERO benchmarks
+- `RoboTwin 2.0 <https://github.com/RoboTwin-Platform/RoboTwin/tree/IsaacLab-Arena>`_ — Extended simulation
+  benchmarks using Arena (`arxiv <https://arxiv.org/abs/2603.08164>`_)
+- `LeRobot Environment Hub <https://huggingface.co/blog/nvidia/generalist-robotpolicy-eval-isaaclab-arena-lerobot>`_ — Share
+  and discover Arena environments on Hugging Face
+- **Coming Soon:** NIST Board 1, NVIDIA Isaac GR00T Industrial Benchmarks, NVIDIA DexBench, NVIDIA RoboLab, and more.
+
+
+**Developer preview branches**
+
+- **A developer preview of Isaac Lab-Arena 0.2 (based on Isaac Lab 2.3) is now available** on
+  `main <https://github.com/isaac-sim/IsaacLab-Arena/tree/main>`_.
+  This early version includes the 0.2 features and is meant for users who can accept some instability.
+- **Isaac Lab-Arena 0.2 on Isaac Lab 3.0 is underway in a dedicated feature branch**
+  `feature/isaac_lab_3_newton <https://github.com/isaac-sim/IsaacLab-Arena/tree/feature/isaac_lab_3_newton>`_.
+  This branch is subject to significant changes and instability as Lab 3.0 (Newton) is evolving quickly.
+- **The official, stable, and tested release of Isaac Lab-Arena 0.2 on Isaac Lab 3.0 is coming soon in April 2026.**
+
+
+**Collaboration**
+
+Isaac Lab-Arena is being developed as an open-source, shared evaluation framework that the community can
+collectively enhance and expand. We invite you to try Isaac Lab-Arena 0.2 Alpha, share feedback, and help
+shape its future. In Alpha stage, development velocity is high and core features/APIs are evolving. Your
+input at this stage is especially valuable.
+
+**What's Next**
+
+Future releases will focus on agentic, prompt-first scene and task generation, non-sequential long horizon
+tasks, easy-to-configure sensitivity analysis with targeted environment variations and evaluation sweeps without
+code changes, enhanced heterogeneity across parallel evaluations, and VLM-augmented analysis to surface
+insights from large-scale evaluations. These will come with ongoing improvements to performance and usability,
+such as PIP packaging.
+
+**Limitations**
+
+- pip install support is coming soon (current installation method is Docker-based).
+- Performance is not yet hardened for production-scale workloads in Alpha stage.
