The ArrayFire Roadmap

In quarterly Meetings of the Maintainers, we review the following roadmap setting a high-level direction for future work. The suggested version numbers and features are not binding and often change. The information is updated once per quarter.

ArrayFire 3.10 (Jul 2024)

Improved oneAPI performance
Continuous delivery
- Support more distro packages
  - Based on Debian [2 hours]
  - Cent OS 7/8 [16 hours]
  - Perhaps Amazon Linux AMI (or more cloud providers) if it gives a better experience for users compared to using sh files
- Python CI [16 hours]
Debugging/Diagnostic functions [2 hours]
Random Shuffle
- https://numpy.org/doc/stable/reference/random/generated/numpy.random.permutation.html
Stream function/Input streaming [80 hours]

ArrayFire 3.11 (Jan 2025)

Data Frames
JIT CPU
Multi-GPU
Multiple backend interoperability
CPU Optimization/Parallelism
OpenCL targeting multiple devices(CPU specific kernels)

ArrayFire 4.0 (Jul 2025)

Support only float/double for pow
ND Arrays? Is there interest that should be answered before implementation?
Drop unnecessary type support for existing API; for example, drop unused types from image processing.
Char -> bool types
Merge index and index_gen
Merge assign and assign_gen
