Git 2.56's git add --resolved stages only conflicted files and refuses to run while conflict markers remain, according to a dev.to walkthrough. Teams that still type git add -u after a merge can drop that habit once every machine they use runs 2.56.
Reality
Git 2.56 adds a staging flag that aborts on leftover conflict markers and cuts one Chromium diff from about eight minutes to 0.07 seconds. Teams get the speed by upgrading, but they get the safety only by editing the scripts their developers and coding agents run.

Git 2.56.0 ships a merge-base stopping rule that GitHub measured at around 70 times faster in many cases on one large monorepo. Whether a build fleet sees gains like that depends on its repositories having old side branches merged into long histories.

Killed git fetches leave tmp_pack files that git gc ignores until they are two weeks old, a dev.to post found after tracing one user's 6 GB repo to them. Once git fsck confirms only garbage, an immediate prune clears them without touching commits.

Delta's public beta puts review inside the thread that produced the code. Commits stay the checkpoints you push, and an existing CI provider still runs the verification an agent triggers before a change lands.

A dev.to walkthrough runs each undo case in a throwaway repo on git 2.43.0. Status columns tell you where the change lives; whether a colleague already pulled the commit is the part you have to know yourself.

Git's binary search closed a twelve-commit range in four automated test runs. It holds up only when the test exits 0 on pass and still runs when Git checks out a commit from a week ago.

The Brooklyn startup's September 11th manifesto puts a custom engine behind a Git bridge, so laptops and CI keep working unchanged. The post carries no production benchmarks and names no trial partners.
