On behalf of the PySAL development team, I'm happy to announce the
official release of PySAL 1.2.

PySAL is a library of tools for spatial data analysis and
geocomputation written in Python. PySAL 1.2, the third official
release of PySAL, brings a number of new features:

    - Directional (Space-Time) LISA Analytics
    - LISA Markov Spillover Test
    - Spatial Markov Homogeneity Tests
    - Markov Mobillity Indices
    - Support for a wide variety of spatial weights formats including
        - AcGIS SWM, Text, DBF
        - STATA
        - MATLAB MAT
        - MatrixMarket MTX
        - Lotus WK1
        - DAT
        - and others
    - RTree spatial index
    - Getis-Ord G statistics for global and local autocorrelation
    - Optimized conditional randomization for local statistics
    - Optimized Block/Regime Spatial Weights
    - Thin Spatial Sparse Weights Class (WSP)

along with many smaller enhancements and bug fixes.
