+# v1.7.0
+
+## Highlights
+
+1) DistributedSampler for efficient data loading and shuffling across multiple nodes with PyTorch
+2) Randomized Symmetric eignevalue decomposition (eigh)
+3) Incremental SVD directly from an HDF5 file
+4) Partial support of the Array API Standard (version: '2020.10'), and API namespace under `x.__array_namespace__(api_version='2020.10')`
+5) Distributed PTP (peak to peak) function
+
+*SVD, PCA, and DMD have been implemented within the project ESAPCA funded by the European Space Agency (ESA). This support is gratefully acknowledged.*
