• Add S-information and negentropy; enhance earth mover's distance
• Add polynomial-time CAEKL via Chan–Liu PSP across numpy/JAX/PyTorch/PyTensor backends
• Speed up exact functional common information (MSS/GK seed search, label-based partitions, bidirectional routing) and track the optimal partition

New subsystems

• Add symbolic (sympy) distributions and measures, plus symbolic common-information solvers
• Add polar source coding (Arikan source polarization)
• Add UpSet plot visualization for multivariate Shannon atoms (dit.visualization)
• Add dit.example_dists.empirical with Titanic, blood types, congressional voting, Palmer Penguins, UCI Car/Student, and Bach & Corelli music distributions

Fixes & maintenance
