Git 2.29 introduces several new features and improvements, with contributions from over 89 developers, including 24 newcomers. One of the most significant updates is the experimental support for SHA-256, aimed at enhancing security by transitioning from the SHA-1 hash algorithm, which has known vulnerabilities. Although currently, repositories using SHA-1 and SHA-256 cannot interoperate, future releases plan to address this limitation. Additionally, the update introduces negative refspecs, simplifying the exclusion of specific branches during fetch operations, and enhancements to git shortlog, which now allows grouping commits by co-authors or other trailer fields. The release also includes various minor enhancements, such as improved performance for multi-core machines and clearer merge conflict messages, alongside a re-enabling of protocol v2 as the default. These updates reflect Git's ongoing efforts to enhance functionality, security, and user experience.
