# Overview

Welcome to Cardano – Upgrades, this space will provide relevant information on major updates and hard forks.

Each major update or change will have its own sub-section including, where applicable,  general information and overviews, any readiness or deployment information and frequently asked questions. Following deployment any lessons learned, feedback and completion reports.
