Bitcoin Core v31.0 Officially Released
Bitcoin Core officially announced the release of Bitcoin Core v31.0. This version includes several underlying updates and improvements, primarily: upgrading the GUI framework to Qt 6.8; increasing the default database cache from 450 MiB to 1024 MiB on systems with more than 4 GB of RAM; and adding support for the `-privatebroadcast` option to enable private transaction broadcasting. Additionally, to prevent fee estimation errors, the `-paytxfee` startup option—which previously allowed setting a static transaction fee—has been completely removed; users must now rely on automatic fee estimation or specify a fee rate per transaction. Furthermore, the new version applies privacy and security filtering to commands used during wallet recovery and migration.
