Git has released Git 2.47 with features and bug fixes from over 83 developers, 28 of whom are new contributors.
This release focuses on performance improvements and an enhanced user experience.
Key Changes:
🟠Incremental multi-pack indexes: experimental feature allowing multiple multi-pack indexes to be stored in a MIDX layered chain;
🟠Faster base branch identification: new for-each-ref tool helps identify a commit’s base branch by minimizing unique commits from the first parent, simplifying identification;
🟠Updated support policy: Git 2.47 introduces a new document outlining support requirements for various platforms, including C99 or C11 standards and stable dependency versions;
🟠DEVELOPER=1 mode: compiling with DEVELOPER=1 now treats unused parameters as a compile-time error;
🟠Other improvements: enhancements to server-side reftable, updated modular testing framework, improvements to git fsck, and Visual Studio Code integration with git mergetool.
