GoKawiilGit 3.0 set to make SHA-256 the default hash, replacing SHA-1
The upcoming Git 3.0 release will switch the default object hashing algorithm from SHA-1 to SHA-256, a change the author argues will disrupt workflows across the Git ecosystem. Git uses hashes as keys in its content-addressable object database, and the author notes that no accidental SHA-1 collision has ever occurred across the billions of commits, trees and files created in Git's 20-year history.
