Bitcoin Core Major Release: Navigating the Changes in v30.0

Bitcoin Core is shaking things up again! The latest major release, v30.0, has arrived, bringing with it a wave of updates and, as always, some interesting debates within the Bitcoin community. Let's break down the key changes and what they mean for you.

What's New in Bitcoin Core 30.0?

Bitcoin Core 30.0 comes months after v29.0 and introduces a range of updates, including:
