* Added `add_event` and `add_cleanup_event` methods and `cleanup_events` and `num_cleanup_events` properties to the order manager, for tracking the events that gate the release of objects used by offloaded tasks [gh-2359](https://github.com/IntelPython/dpctl/pull/2359)
* Added `SyclQueue_DeferRelease` C-API function, which defers a release callback until work submitted to a queue completes, and through which `dpctl::utils::keep_args_alive` keeps its arguments alive [gh-2359](https://github.com/IntelPython/dpctl/pull/2359)
* Added `dpctl::utils::defer_release` to `dpctl4pybind11.hpp`, which calls a release callback once the given events have completed [gh-2359](https://github.com/IntelPython/dpctl/pull/2359)
* Added `dpctl.SyclPlatform.has_aspect_*` properties and the `DPCTLPlatform_HasAspect` C-API function for querying aspects supported by all devices of a platform [gh-2412](https://github.com/IntelPython/dpctl/pull/2412)

### Changed
* Object lifetime during offload is now managed by a list of releases deferred until the events that gate them have completed, rather than by a `host_task`. `dpctl` keeps one thread for looking over the list and running the releases that have come due, started by the first release deferred and again in the child of a `fork`, which takes the GIL to do so and lets a release call into the interpreter and free USM allocations [gh-2359](https://github.com/IntelPython/dpctl/pull/2359)
