Bitcoin Core version 29.0rc2, the latest update since version 28.0 in October 2024, brings significant changes to the peer-to-peer network, mempool policy, and mining processes. The update also includes new remote procedure calls (RPCs) and updated REST APIs. One notable addition is the introduction of "ephemeral dust" for dust outputs in zero-fee transactions, requiring them to be spent with other outputs in a single transaction package. This release aims to improve efficiency through mempool and mining adjustments. The updated Bitcoin Core version is now available for testing, with enhancements to the wallet and build system, including GUI improvements and a transition to CMake from Autotools. These changes aim to enhance network security and user experience, solidifying Bitcoin's position as a leading cryptocurrency.
