Release notes

v1.9.0 | Jul 28, 2026​

  • Engine profiles no longer accept a null value for GPU tolerations. A profile that already stores one now keeps the tolerations from its pod template instead of clearing them.
  • Added documentation for engine profiles.
  • Added an administration guide covering role-based access control, engine profile security, authentication and authorization, and the audit trail.
  • Minor fixes and improvements.
  • Security updates.

v1.8.0 | Jun 3, 2026​

  • Fixed the Python client returning no output when streaming Sandbox Engine process output. The stream now yields chunks tagged stdout or stderr, so scripts that expected raw bytes must now read each chunk's data.
  • Fixed intermittent connection errors on newly started Sandbox Engines.
  • Fixed Sandbox Engines failing to run on Red Hat OpenShift and other platforms that assign arbitrary container user IDs.
  • Minor fixes and improvements.
  • Security updates.

v1.7.0 | May 20, 2026​

  • Added a required running-time limit to Sandbox Engine templates. An engine is terminated once it reaches the limit regardless of activity, and zero means no limit. Existing templates default to zero, but scripts that create or update templates must now set this limit.
  • Added Python client method to read Sandbox Engine process output as ordered frames tagged stdout or stderr.
  • Added configurable token scopes for deployments that use the Token Server.
  • Updated Sandbox Engine API to align with Sandbox v0.5.0, now the minimum version for Sandbox Engine images.
  • Fixed enforcement of the Sandbox Engine idle limit, which earlier versions ignored. A Sandbox Engine that exceeds the limit set in its template is now terminated and cannot be resumed.
  • Fixed large-file H2O Drive uploads and downloads in Sandbox Engines.
  • Minor fixes and improvements.
  • Security updates.
