> For me this outputs Bun v1.4.0 (macOS arm64). The most recent release of Bun on GitHub is currently v1.3.14 from May 12th, so that v1.4.0 version number in Claude supports them shipping a preview of a not-yet-released Bun version.
I don't know for certain, but it seems likely that it is given that Jarred said "Claude Code v2.1.181 (released June 17th) and later use the Rust port of Bun".
What motive could he have for secretly maintaining a private fork of Bun that's shipped with Claude Code while simultaneously working on the open source repairs every day?
yeah the word "unreleased" makes it sound so mysterious
i am a clankersceptic as much as the next guy and i hate "anthropic" for participating in the murder of innocent people (maven "smart" system, offers them as a provider to the pedo criminal unitedstatistan government)
but this whole "unreleased" framing is just manufacturing drama / lack of knowledge
A charitable interpretation is that the version of bun inside Claude Code corresponds to some recent state of their public git repository, so if you clone that, you more or less get the same thing.
I don't see what it would buy Anthropic to have some sort of secret internal fork with special private code in it.

Which is still true as I write this comment.
The code is on GitHub in the "main" branch, it's only unreleased in that it hasn't been tagged with a version number yet.
If it hasn't been tagged with a version yet, how do you know (or what makes you think) it's the same as this 'v1.4'?
