DESILO FHE Library v1.7.0 Release Notes

DESILO FHE Library v1.7.0 is now available (released 2025-11-12). Highlights:

• Matrix multiplication is now available. This can be done in two ways, a faster version with a matrix multiplication key which requires more memory, and a slower version with a rotation key which requires less memory. This feature is not yet available for multiparty computation.
• PyTorch tensors are now supported as input. PyTorch is not in the requirements to allow the user to choose the version of PyTorch.
• Sign bootstrap is now available. This special bootstrapping method can bootstrap sign (-1, 1) values more accurately. This requires the lossy bootstrap key.
• Python versions from 3.10 to 3.14 are now supported. Python 3.9 is no longer supported.
• CUDA 13.0 is now supported.
