Added

Complete support for sycl::ONEAPI::filter_selector in dpctl.
C API for sycl::queue (#323), syc::context (#331), and sycl::platform (#298) creation using opaque pointers.
A DPCTLDeviceMgr module in C API that caches a default context for root devices (#277).
DPCTLSyclBackendType and DPCTLSyclDeviceType have a new member ALL (#287).
C API now provides helper functions to convert between dpctl and SYCL enum values (#296).
Macros to help create opaque vector classes for opaque SYCL types (#297).
SyclDevice (#321), SyclContext (#334), SyclPlatform (#336, #298), SyclQueue (#323) have constructors that recognize filter selectors and closely follow DPC++ interface.
Add API to get a PyCapsule from SyclQueue, SyclContext instances (#350).
Added get_queue_ref_from_ptr_and_syclobj(ptr, syclobj) that creates DPCTLSyclQueueRef from a USM pointer and Python object syclobj from __sycl_usm_array_interface__ (#380).
Support for SYCL sub-devices, including sub-device creation, queue, and context creation using sub-devices (#343).
SyclDevice.parent_device property to indicate if an instance has a parent device (#366).
Several new getter functions for device info descriptors to device interface (#300, #335, #318, #315, #308).
Support for SYCL device aspects (#307).
Properties for every sycl::device info and aspect that we support in SyclDevice (#324).
Support handling async errors inside SylQueue instances (#346).
get_backend, get_platform, get_device_type to Python SyclDevice class (#300)
A _sycl_device_factory.pyx module providing SyclDevice constructors using standard sycl::device_selector classes (previously in _sycl_device.pyx) and a new get_devices (#277) function to enumerate all devices.
_sycl_device_factory.pyx implements get_num_devices and has_*_device(s) functions (#320).
Enable Python coverage in CI for Linux (#369).
Use public keyword in _sycl_*.pxd to generate header files allowing non-Cython centric native extensions to work with dpctl's Python objects (#218).
Documentation improvements (#341).

Changed

Rename dpCtl to dpctl in all comments, license headers, and docs. (#342)
dpctl.memory.MemoryUSM* constructors now use dpctl.SyclQueue() instead of dpctl.get_current_queue() when the queue keyword argument is None (default) (#382).
dpctl.set_default_queue has been renamed to dpctl.set_global_queue() (#323).
Changed dpctl.dump to dpctl.lsplatform (#336).
Various SyclDevice methods related to querying sycl::info::device were converted to properties (#324).
Various C API functions names were changed.

Fixed

Possible crashes when a SYCL platform is not available (#349).
Fix tests which fail if GPU is not available (only CPU is available) (#359).
Fix breaking C API tests (#358).
Bandit warning about "subprocess.check_call(shell=True)" for Windows (#306).

Removed

Removed get_num_platforms, has_cpu_queues, has_gpu_queues, get_num_queues, has_sycl_platforms (#320).
