+## [0.7.1] - 2026-07-14
+
+- Adds CUDA classic JPEG 2000 Tier-1 code-block decoding with shared host/device
+  MQ and context tables, batched resident submission, bounded host accounting,
+  and explicit CUDA ABI and unsafe-boundary inventories.
+- Adds an opaque, zero-copy Metal resident-image contract with checked layout
+  and device identity, submission-owned input and output lifetimes, safe
+  decoder-to-encoder handoff, and explicit unsafe raw-buffer interop.
+- Improves Metal decode residency with dynamic pool ceilings and enforced
+  inflight limits, fixes irreversible inverse-MCT addends, fuses native inverse
+  MCT output handling, and uses a staged irreversible 9/7 IDWT implementation.
+- Adds hardened CUDA and Metal profiling/capture controls and documents their
+  benchmark-only environment variables.
+- Adds the unpublished experimental `j2k-ml` workspace crate with CPU and Metal
+  validation paths and an optional CUDA-Oxide kernel route.
