Responding to VAR updates

I need to respond to a Chinese user's message about updated VAR rules for the Football World Cup, but my last knowledge was in October 2024. It’s now December 2025, so I might not have the very latest updates. I could clarify by asking which tournament they're interested in or provide a summary of the 2024 updates, like the changes to semi-automated offside technology and VAR protocol clarifications.Clarifying VAR updates

The EPL voted to introduce semi-automated offside technology in autumn 2024 and also decided to scrap on-field reviews for some factual offsides. They’re exploring the idea of broadcasting referee audio after matches. There's been a trial of communicating VAR decisions live during tournaments, and FIFA plans to use similar methods for the 2026 World Cup. Given the ambiguity in the user's question, I should ask for clarification: are they interested in what's new, when it will be implemented, or which source to refer to?Summarizing expected VAR updates

I need to summarize the likely VAR updates for the 2026 World Cup. SAOT will continue, with in-stadium announcements expected, and it seems there's a plan to reaffirm that VAR will only address clear and obvious mistakes. There might be a new offside "tolerance zone," and the distinction between "clear line" and thicker lines is also relevant. Since the user mentioned VAR updates, I should ask if they want a quick summary of the latest changes and clarify which competition they're interested in.
