Quick update on Voyager SDK 1.5.2, which was just rolled out and sorts out a few issues from 1.5.1 while adding some quality of life improvements.

What's fixed:

The main focus here was stability. This version sorts the build failures that were hitting ImageNet networks when using HINT instructions, fixed NormaliseCL so it properly handles inputs that aren't 4-channel, and stopped those segfaults in YOLO decoders when they got an unexpected number of input tensors.

New bits:

Runtime can now execute AXM files directly, which should make deployment a bit more straightforward. It adds selectable network protocol for RTSP sources in inference.py (gives you more flexibility with inputs), and there are new create_inference_net overloads so existing code compiles without needing a context parameter.

The docs have been updated to reflect the AXM execution changes, plus general tidy-ups across tutorials and references.

That's it! Nothing earth-shattering, just the solid incremental improvements we love. As always, if you run into any issues or have questions, drop them in the community and we'll sort you out.ย ๐Ÿ‘
