Changelog

All notable changes to the RunAnywhere QHexRT Backend will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

0.20.19 - 2026-08-14

• QHexRT catalog: added the lfm2_5_1_2b_thinking policy row. The app catalogs already shipped that model, but the engine had no row for it, so device-aware registration failed with -259 ("unknown QHexRT native catalog model id") on a real v81 device. The bundle is public and v81 only.
• QHexRT catalog: lfm2_5_vl_3b no longer requires an HF token. Its repo (runanywhere/lfm2_5_vl_3b_HNPU) is public, so the stale auth gate was hiding a public model from the picker.
• Note: this package still ships no natives from pub.dev by design. The Qualcomm QNN libraries are private and must be staged separately; without them the SDK reports QHexRT unavailable and continues.

0.20.18 - 2026-08-12

• Commons: backend registration failures are isolated. An engine that cannot register is recorded as unavailable instead of aborting SDK initialization, so the remaining backends keep serving.
• Suite version bump. This release also rebuilds the Electron backend plugin natives; that part does not affect this package.

0.20.17 - 2026-08-11

• Electron QHexRT backend and its commons platform-capability changes.
• Swift package is now consumable by version (from:) rather than only by git revision.
