  "account": "Git 3.0 will introduce SHA-256 as the new default content hashing algorithm, which the author warns could prove to be an expensive and largely unnecessary change. The current default algorithm, SHA-1, has been considered secure for the last 20 years, with no known collisions or second-preimage attacks that would affect Git's integrity. The SHA-256 algorithm is stronger, but the shift to it may incur significant costs and cause unnecessary headaches for developers.",
