 ## [Unreleased]
 
+## [0.39.1] - 2026-08-11
+
+Headline: **eager overhead off the JVM is gone.** The eager CPU ops gain
+primitive FP32 fast paths, removing the per-element allocation/boxing overhead
+that dominated on-device LLM decode (83% of end-to-end time on a Pixel 8a even
+with NEON matmul), and `DirectCpuExecutionContext.ops` is cached instead of
+rebuilt per access. The README now points LLM users to SKaiNET-transformers.

+- **Eager CPU ops run primitive FP32 fast paths.** The generic per-element paths (index-array allocations, boxed accessors, dtype dispatch) dominated on-device LLM decode — 83% of end-to-end SmolLM2-135M decode time on a Pixel 8a was non-matmul overhead even with the NEON backend. Hot ops (arithmetic, activations, unary math, softmax/logSoftmax, reductions, concat, reshape) now run flat primitive loops over the dense `FloatArray` buffer, benefiting every non-JVM target — Android, Kotlin/Native, JS/Wasm. `DirectCpuExecutionContext.ops` is also cached instead of rebuilt per access.
+- **README points LLM users to SKaiNET-transformers.** A callout under "Start in 5 minutes" makes clear that LLM inference lives in the SKaiNET-transformers repository — this repo is the engine underneath.

+### Previously, in 0.39.0
 
 - **On-device AI on Android — a NEON kernel backend.** New `skainet-backend-jni-cpu` module: the hand-tuned ARM matmul kernels reach Android through a JNI bridge (ART has no `java.lang.foreign`, so the FFM provider can never run there). Two `.so` tiers are built from the same sources and selected at load time from `/proc/cpuinfo` — a baseline `armv8-a` build that runs on every 64-bit core, and an `armv8.2-a+dotprod` build for the `vdotq_s32` Q4_K/Q6_K paths — so a single artifact is safe from Cortex-A53 up. Measured on a Pixel 8a: **~24 tok/s** SmolLM2-135M Q8_0 decode versus ~3.8 scalar (6.4x), clearing the on-device usability bar. The provider auto-registers via `ServiceLoader`; an app just adds the AAR.
 - **Android GGUF loading no longer OOMs.** `createRandomAccessSource` returned `null` on Android, forcing every model load through a full-file heap read that exhausted the ART heap on real devices. It now streams via positional `FileChannel` reads across `skainet-io-gguf` / `-safetensors` / `-onnx`.

 Each cell is the best (highest-priority) provider that serves `Float32 × format` `matmul` on that platform: *native-ffm* (100) → *panama-vector* (50) → *scalar* (0). An empty cell (`—`) means no provider carries a kernel there (the format is dequant-to-FP32 only).
