Bitcoin Core v30.0 Deploys Major OP_RETURN Change

The latest version of Bitcoin Core software, v30.0, has been released, introducing a significant change to the way transactions utilize data through the OP_RETURN function. This update removes the long-standing 80-byte limit on this function, allowing for significantly larger payloads within transaction data. Previously, users were limited to small pieces of data, but now nodes can store data up to several megabytes depending on the block size.
