According to Wu Blockchain, Bitcoin Core has officially announced the release of Bitcoin Core v31.0. This version brings several underlying updates and improvements, including: updating the GUI framework to Qt 6.8; increasing the default database cache for systems with more than 4GB of memory from 450 MiB to 1024 MiB; and adding -privatebroadcast to support private broadcast behavior. Additionally, to prevent fee calculation errors, the new version has completely removed the -paytxfee startup option for setting static transaction fees. Users will now need to rely on automatic fee estimation or specify fees for individual transactions. The update also introduces privacy and security filtering for commands used during wallet recovery and migration. https://(wublock123.com)/news/bitcoin-core-v31-0-release-59860
