Released this week: v0.3.3 through v0.3.10

​
New features

Microsandbox rewrite Rewritten around an embeddable SDK, smoltcp-based networking, and a composable filesystem:
  • First-class Rust SDK that the CLI is built on.
  • User-space network stack (smoltcp) with an in-sandbox DNS resolver and TLS proxy.
  • Composable filesystem layering OCI images, host volumes, and writable overlays through one VFS.
  • Redesigned policy and config model shared across CLI, SDK, and Sandboxfile.
Breaking change. Other features
  • Per-command exec flags for msb run. Pass --env, --workdir, --tty, --timeout, etc. directly without a Sandboxfile.

​
Bug fixes

  • VM logs split into guest.log and host.log instead of interleaving.
  • Reopening inodes via /.vol on macOS no longer fails under O_RESOLVE_BENEATH.
  • Overlay readdir resolves real inode numbers instead of surfacing 0.
  • ExecTimeout is returned consistently when an exec call hits its timeout.
  • Sandbox creation validates workdir up front and defaults cwd to / when unset.
  • msb self update resolves the latest version before downloading the bundle.
