The latest version of Bitcoin’s flagship software, Core 30.0, has been released. This update brings performance enhancements, bug fixes, policy changes, and a significant overhaul to the user interface. One of the most notable additions is higher transaction limits for signature operations, allowing for more complex transactions and greater flexibility. Support for multiple OP_RETURN outputs and reduced default transaction fees are also included. The update completely replaces the legacy wallet system with the modern Qt 6 interface for a smoother user experience.** Users running versions 27.x or older are encouraged to upgrade. The new version introduces stricter limits on signature operations, capping the number at 2,500 per transaction. This measure is designed to prepare for upcoming BIP54 updates and ensure smooth network operation. A crucial caveat: if low-fee defaults aren’t widely adopted across the network, these settings might not be confirmed as reliably. *This is not investment advice.*
