HyperSpy is an open-source Python library, currently at version 2.4.0, providing a comprehensive framework for the interactive analysis of multidimensional datasets, particularly within scientific domains like electron microscopy. It offers tools for efficient exploration, manipulation, and visualization of complex data arrays, including those larger than available memory. The project maintains an active development pace with several minor releases annually, and significant architectural changes in major versions like 2.0.
