v1.2

This version intrduces the following new changes to the standard

• Add support for Trainium device in #168
• Enforce strides to be not null when ndim is nonzero in #178
• Support DLPACK C Functions for Speed Exchange and Stream Handling in #174

Full Changelog: v1.1...v1.2

v1.1

This release mainly focuses on low-precision data type support that is increasingly relevant in latest ML workloads

• Added support for F8
• Added support for F4
• Added support for F6

v1.0

This release tags DLPack v1.0 release.

• Introduce versioning DLManagedTensorVersioned
• flags about exported tensor

This release acompanies array api changes, see the note below

Starting Python array API standard v2023, a new max_version argument is added to __dlpack__ for the consumer to signal the producer the maximal supported DLPack version. Starting DLPack 1.0, the DLManagedTensorVersioned struct should be used and the existing DLManagedTensor struct is considered deprecated, though a library should try to support both during the transition period if possible.

DLPack v1.0 rc

This release tags DLPack v1.0 release candidate. Main changes include

• Introduce versioning DLManagedTensorVersioned
• flags about exported tensor

v0.8

This is last release before DLPack ABI change to add versioning

• Add kDLBool

v0.7

This release adds the following fields

• Add kDLHexagon
• Add kDLOneAPI
• Add DLPACK_VERSION and DLPACK_ABI_VERSION

v0.6

• Add kDLROCMHost
• Add kDLCUDAManaged

v0.5

Rename enum names:

• kDLGPU -> kDLCUDA
• kDLCPUPinned -> kDLCUDAHost

The ABI is backward compatible, as it is only change of constant name, exchange can still happen between the new version and old version.

v0.4

• OpaqueHandle type
• Complex support
• Rename DLContext -> DLDevice
  • DLTensor.ctx -> DLTensor.device
  • This requires dependent frameworks to upgrade the type name.
  • The ABI is backward compatible, as it is only change of constant name, exchange can still happen between the new version and old version.

v0.3

Minor release

• Add bfloat16
• Vulkan support
