> 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.
And so, the FOSS project "Bun" silently dies in darkness and is now something completely else. I'm glad I still had "Investigate if Bun is worth it" on my TODO list and hadn't yet gotten to it.
What is the governance structure for Bun by the way? Couldn't find any documents/explanations about how it's supposed to work. I'm guessing it's essentially just "Anthropic decides what gets done and accepted" today?
The PR is public, you can build and use it as well. The anthropic team just decided to use it, and you can as well.
It's largely just what jarred is willing to accept this week afaik or not, and they did put the bun 1.4.0 version bump in the changelogs for claude code a while ago, over a month almost.
Though most will be forgiven to not reading it since well it's all AI anyways. I don't know how I feel about all this yet, maybe someday.. ooof
I had "investigate if bun is worth it" too, and decided not to use it, but instability was one of the reasons. So it feels it was the right move.
Why does changing to Rust kill the project? I don't understand the point here.
