Version 30.0 of Bitcoin Core, the most popular full-node software for Bitcoin (BTC), has been released. New versions include performance improvements, bug fixes, and policy changes.
The most notable innovations include increasing the signature transaction limit, supporting multiple OP_RETURN outputs, and lowering the default transaction fee rate.
The new version also includes significant changes to Bitcoin Core’s wallet and graphical interface (GUI) components. The traditional wallet system has been completely removed and the software has been migrated to the Qt 6 interface. The developer recommends that users using version 27.x or earlier upgrade to the new version.
Bitcoin Core 30.0 introduced new restrictions on signature operations in preparation for future BIP54 updates. The number of signature operations in a single standard transaction is currently limited to 2,500. This change is not expected to affect normal transactions.
Developers warn that if these low-fee defaults are not rolled out across the network, low-fee transactions may not be confirmed.
