## Recent releases

| Version | Date | Urgency | Changes |
| --- | --- | --- | --- |
| `1.3.5` | 2026-05-22 | High | ## Bug Fixes  - **FP16 NEON build fixed on AArch64 CPUs without FP16FML** (`src/quant/float16.hpp`)   Some AArch64 CPUs lack the `FP16FML` extension, causing build failures on missing `vfmlalq_low_f16`/`vfmlalq_high_f16` intrinsics. Compatibility fallbacks using standard NEON (`vcvt_f32_f16 + vfmaq_f32`) are now compiled in automatically. CPUs with FP16FML still use the native single-instruction path.  - **Backup upload refactored into `IndexManager`** (`src/core/ndd.hpp`, `src/main.cpp`) |
