Release notes#

Faber script kernel and frame/script e2e hardening route. This release completes the binary-owned Faber script kernel (phases 1–3) and drives the MIR stepper through a large e2e hardening campaign that adds tensor intrinsic execution, collection operations, conversions, and frame-gateway host streaming. A new AIR (Abstract Intermediate Representation) layer is introduced and routed through MIR targets.

Scale#
