Patch Changes

  • #1028 `2e4e1eb` Thanks @ghostwriternr! - Update the container runtime to Bun 1.4.4. Bun checks certificates against its own built-in CA list, and in 1.4.4 that list no longer trusts the compromised eMudhra intermediates, so the bun command and createBackup() uploads of 10 MiB or more now reject their certificates. Bun 1.4.4 also updates Brotli to 1.2.1, which fixes CVE-2026-111497. The -opencode image ships OpenCode 1.19.4 or later, which also runs on Bun 1.4.4.
