Git Сelebrates 20 Years With the Release of Version 2.50, Featuring Major Improvements

Описание: On June 16, 2025, Git 2.50 was released — a major update to one of the world's most popular version control systems. The anniversary version, timed to coincide with the project's 20th anniversary, includes 621 changes made by 98 developers, including 24 new contributors. Git 2.50 is a logical continuation of versions 2.47 (October 2024), 2.48 (January 2025), and 2.49 (March 2025), continuing the focus on performance optimization and modernization of the system's internal components.

Working With Unreachable Objects Has Become More Efficient
One of the key improvements concerns working with so-called “cruft packs” — archives with objects that are not referenced by either branches or tags. It is now possible to split such pack files into several smaller ones, which reduces the load on the disk when repackaging. There is also a new option, --combine-cruft-below-size, which allows you to combine small pack files without limiting the final size.

Updating Multi-Pack Indexes and Removing the Old Merge Engine
Git 2.50 implements experimental support for incremental MIDX (multi-pack index) updates, where each index level is stored separately as a bitmap file. This is especially important for large repositories where speed is important when adding new objects.

The outdated recursive merge engine has also been completely removed from the code, giving way to the more modern and efficient ORT (Ostensibly Recursive's Twin). The new engine works faster, requires fewer write operations, and is easier to maintain.
