+## [0.20.27] - 2026-08-24
+
+### Changed
+
+- The Apple Neural Engine (NeuRT) and Hexagon NPU (QHexRT) engines now ship from
+  pinned, prebuilt archives published by the private engine repository rather
+  than being compiled from source. Each archive is verified by SHA-256 and by a
+  build receipt naming the plugin ABI version it was built against.
+- The Hexagon engine's QAIRT/QNN runtime dependency is now pinned and fetched
+  the same way — as a private, checksum-verified artifact from the engine
+  repository, paired against the engine's own build identity so the two can
+  never silently drift apart.
+- No Flutter-facing API change.
