The post, published October 1, 2026, doesn't take issue with SHA-256 itself - it objects to changing the default before the wider Git ecosystem, including hosting services, tooling, and existing repositories, is ready for it. The piece sparked a lively discussion thread, pulling 46 points and 29 comments within a day.\n\nGit's SHA-1 to SHA-256 migration has been in the works since 2017, after researchers showed SHA-1 could be practically broken. But adoption outside Git's own test suite has crawled, because nearly every tool, remote, and integration still assumes SHA-1 object IDs. Flipping the default in 3.0 pushes that compatibility question onto every developer who starts a new repo, not just the maintainers who have spent years laying groundwork for the switch.\n\nGit has floated this transition for the better part of a decade without touching a single default. Whether 3.0 is the moment that finally changes, or another false start, is hard to judge from one blog post and a comment thread.","[\"git\",\"sha-256\",\"version-control\",\"open-source\"]","2026-10-01T16:57:03.000Z","2026-10-02T16:10:43.120Z","2026-10-02T16:10:48.295Z","published",null,[],"dev-tools",[26,27,28,29],"git","sha-256","version-control","open-source",[31],{"name":32,"url":33},"Hacker News","https:\u002F\u002Fblog.gitbutler.com\u002Fgit-3-sha-256",0,{"sections":36},[37,42,47,52,57,62,67,72,75,80,85,90,95,100],{"name":38,"slug":39,"count":40,"latest_published_at":41},"AI","ai",5721,"2026-10-01T19:45:44.000Z",{"name":43,"slug":44,"count":45,"latest_published_at":46},"Security","security",829,"2026-10-01T17:31:56.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":51},"Policy","policy",437,"2026-10-01T18:10:00.000Z",{"name":53,"slug":54,"count":55,"latest_published_at":56},"Deals","deals",317,"2026-10-01T22:00:00.000Z",{"name":58,"slug":59,"count":60,"latest_published_at":61},"Hardware","hardware",198,"2026-10-01T17:38:48.000Z",{"name":63,"slug":64,"count":65,"latest_published_at":66},"Science","science",168,"2026-10-01T18:35:55.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Consumer Tech","consumer-tech",155,"2026-10-01T19:54:10.000Z",{"name":73,"slug":24,"count":74,"latest_published_at":18},"Dev Tools",96,{"name":76,"slug":77,"count":78,"latest_published_at":79},"Software","software",93,"2026-09-30T21:41:11.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Startups","startups",90,"2026-10-01T21:55:22.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Gaming","gaming",53,"2026-10-02T02:50:39.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",7,"2026-10-01T09:00:00.000Z"]
