## Summary

Isaac Lab 3.0 has been officially released, and the official recommendation is for new projects and projects migrating from 2.x to use v3.0.0 as their base. The new version adopts a multi-backend architecture with a unified task API, supporting backends such as Newton and OV Libraries. Supported tasks can switch physics, rendering, and visualization backends without rewriting logic, and most workflows do not require installing or launching Isaac Sim.

## Why it matters

The original article lists the specific changes in the multi-backend architecture and the removal of the Isaac Sim installation requirement, as well as the environment and interface changes needed for migration, making it easier to judge the upgrade cost for existing projects.
