What probably matters to youSection of the release
What
Claude Code's plugin system (which lets extensions run code through "hooks" that respond to events) has a new low-level capability called process.spawn. It lets plugin code launch a subprocess and stream its output back, running through the same sandboxed bridge that mediates what plugins are allowed to do on the host machine.
Why
This gives plugin authors a supported way to run external programs and receive their output as it streams in, rather than only making one-shot request/response calls.
