llama.cpp released version b11048 on Sept 19, adding Metal support for two new DSV4 high-context (HC) operation variants used by the qwen4exp model.[^1]

The read here is that the two HC operation variants now have a Metal execution path where the project had none before. For operators running qwen4exp, that is a change worth testing. The record carries no throughput or latency figures for the variants, so the practical gain is not yet quantifiable from this release alone.

A measured run of qwen4exp using these two HC variants on Metal, reporting tokens per second and context length, would give the change a number. This release gives none; its measurable content is the version bump to b11048, dated Sept 19.
