One signal

A GitButler blog post argues that Git 3.0’s planned move from SHA-1 to SHA-256 as the default will bring disruption without much practical security benefit.

Why it matters

The author says hash collisions are not a realistic threat to codebases and argues that trust in source control depends more on where code comes from and how it is distributed. That is a pointed challenge to a consequential change in a tool used across software development. The argument is the author’s, not an established consensus. Still, it raises a useful question about whether a security upgrade is worth the migration costs.

Discuss: Should Git make SHA-256 the default despite the migration burden, or should users opt in until a clearer security benefit is shown?
