v5.4.0

[5.4.0] - 2026-06-24

Highlights

• The indexing direction has been reversed now. Instead of the context_chat PHP app sending documents to the context_chat_backend ExApp, the ExApp downloads the documents from the server according to a list obtained from the PHP app. This also means that the occ context_chat:scan command serves no purpose and has been removed. Indexing should be smoother and run continuously now.
• Kubernetes support to scale the CPU computation
• Separate docker images for CPU, CUDA and ROCM (uses Vulkan) instead of one heavy CUDA/CPU image
• CUDA 12.8 is shipped in the CUDA image so the host drivers should be updated to this at the minimum.
