+Headline: **the native Q8_0 / Q4_0 / Q5_0 / Q5_1 kernel bindings no longer zero the earlier rows of a
+multi-row product** (#1436, see *Fixed*). The defect was in the JVM FFM lane since those bindings exist: a
+single-row product (a decode step) was right, every multi-row one kept only its last row, which made any
+quantize-at-load encoder on the JVM with `skainet-backend-native-cpu` on the classpath — Laya on Q8_0 — answer
+with uniform probabilities. CI never saw it because its classpath has no native provider; the LayaMoE example
+did. Fix releases carry what develop holds: also the YOLO move-out below, the StableHLO softmax axis fixes, the
+*Flexibility at every compile stage* explanation page (#1432) and the SKEEP-008 draft, *Precision and encoding
+conversion* (#1434, tracking #1433).
+
+Also in this release: **model-specific detector code leaves core; the reusable detection pieces stay.**

-## What's New in 0.62.0
+## What's New in 0.62.1
+
+A fix release on top of 0.62.0: the native FFM bindings of the Q8_0, Q4_0, Q5_0 and Q5_1 kernels
+copied a zero-filled staging buffer back from index 0, so a product served row by row — any
+quantize-at-load encoder on the JVM with `skainet-backend-native-cpu` on the classpath — kept only
+its last row. Single-row decode steps were never affected. A regression test now covers every packed
+format for one, seven and fifty rows. Also: the YOLOv8 model code moves out of core into its cartridge
+blueprint (`skainet-model-yolo` is gone; `Letterbox`, `BoundingBox` and `nonMaxSuppression` stay in
+`skainet-data-media`), the StableHLO `softmax` axis and `logSoftmax` lowering are fixed, and the docs
+gain *Flexibility at every compile stage* and the SKEEP-008 draft on precision and encoding conversion.

 Each cell is the best (highest-priority) provider that serves `Float32 × format` `matmul` on that platform: *native-ffm* / *native-jni* / *native-cinterop* (100) → *panama-vector* / *wasm-simd128* (50) → *scalar* (0). An empty cell (`—`) means no provider carries a kernel there (the format is dequant-to-FP32 only). The JS/WASM column assumes `WasmSimd.install()` has run; without the sidecar it is the scalar floor.
