New features

  • Name your snapshots. The JavaScript SDK (e2b@2.20.1) and Python SDK (@e2b/python-sdk@2.21.1) now accept an optional name parameter when creating snapshots, and return the snapshot’s name in the response. See persistence & snapshots for usage.
  • More memory-efficient templates. Template builds now coordinate guest free-page reporting per team, reducing memory usage for paused sandboxes built from the same template.

Updates

  • Cleaner sandbox logs. Sandbox runtime logs are quieter and more reliable: repeat metadata-poll failures are deduplicated, debug events no longer flood the in-VM journal, and the log exporter now buffers safely when the collector is briefly unreachable so log lines aren’t lost during transient network blips.

Bug fixes

  • More reliable sandbox startup. Initialization no longer piles up retries when many requests hit a sandbox at the same time — pending calls now cancel cleanly when your client disconnects instead of queueing behind a stuck lock. The same fix is applied to the in-sandbox trusted CA installer.
  • More reliable sandbox resume. Sandboxes that resume while still holding file descriptors against an NFS mount now fall back to a lazy unmount instead of failing, so resumes succeed in more cases.
  • Trustworthy log identity. Sandbox log lines now always carry the correct template, sandbox, and team IDs as recorded by the orchestrator, even when the in-sandbox agent is unhealthy.
