Several improvements under the hood which don't need to be documented here. API
changes (like storing generated resource claim names in the pod status) are
part of the generated API documentation.
What is worth mentioning because it was listed as "limitation" before is that
pre-scheduled pods are now supported better.
The documentation intentionally only gives an overview. The API documentation
and the KEP have more details. Specific examples will be provided by hardware
vendors that provide resource drivers.
The new page gets placed between "Scheduling Framework" (because that
introduces the concept of a scheduler plugin) and "Scheduler Performance
Tuning" (which seems like a more advanced topic).
