Bitcoin Core version 25.0 has been released, bringing new features, bug fixes and performance improvements to the software. Users can download the latest version from the official bitcoin core Update the website or their existing installations. The release notes outline the changes and provide instructions on how to upgrade.
One notable change is the permission for transactions of non-witness size 65 bytes and above, which opens up new use cases and increases security against vulnerabilities such as CVE-2017-12842. Another addition is Scanblocks RPC, which allows for faster wallet rescans by returning blockhash corresponding to a set of descriptors.
In terms of RPC updates, all JSON-RPC methods now accept a new named parameter called “args” for easier passing of positional parameter values. Additionally, the verification chain RPC will now return false if the probe cannot be completed at the desired depth and level, providing more accurate feedback.
The release also includes build system changes, updated settings, and new features. For example, the shutdownnotify option allows users to specify a command to be executed before Bitcoin Core starts its shutdown sequence. In the Wallet section, new options have been added to the various RPCs, such as minconf and maxconf, which provide more control over UTXO confirmations.
Bitcoin Core 25.0 introduces a number of improvements and optimizations, enhancing the user experience and security of the software. As is the case with any release, users are encouraged to report any bugs to the official GitHub issue tracker.
Bitcoin Core is widely supported and tested on major operating systems such as Linux, macOS, and Windows. However, it is not recommended to use Bitcoin Core on unsupported systems. Users should ensure that they are running a compatible operating system before upgrading to the latest version. In addition, users are encouraged to review the release notes for a detailed understanding of the improvements in this version upon upgrade.
