Release - v5.2.0

To install or upgrade the SDK, refer to instructions here.

Notes

• Starting with Delphix Engine release 2026.5.0.0, uploading a new plugin built with a vSDK version pinned to Python 2.7 or Python 3.8 (see Virtualization SDK and Python Compatibility Map) is rejected. Plugins already installed on an earlier engine are not affected by this change.

New & Improved

• Added support for validating a target before a virtual or linked source is exported to a physical source, via the new pre_source_to_physical operation — a pre-copy counterpart to the existing source_to_physical operation.
  • Use @plugin.virtual.pre_source_to_physical() to validate the target before physical export for VDBs. See Virtual Source Pre-Source-to-Physical.
  • Use @plugin.linked.pre_source_to_physical() to validate the target before physical export for dSources (both direct and staged linking). See Direct Linked Source Pre-Source-to-Physical and Staged Linked Source Pre-Source-to-Physical.
  • Reuses the existing PhysicalSource class — no new schema or generated classes.
