On behalf of the PySAL development team, I'm happy to announce the
official release of PySAL 1.3.

PySAL is a library of tools for spatial data analysis and
geocomputation written in Python. PySAL 1.3, the fourth official
release of PySAL, includes a number of new features and enhancements:

    - The spatial regression module (spreg) has added:
        - Two Stage Least Squares
        - Spatial Two Stage Least Squares
        - GM Error (KP 98-99)
        - GM Error Homoskedasticity (Drukker et. al, 2010)
        - GM Error Heteroskedasticity (Arraiz et. al, 2010)
        - Spatial HAC variance-covariance estimation
        - Anselin-Kelejian test for residual spatial autocorrelation
of residuals from
        IV regression
        - New utility functions and other helper classes
    - A new contrib module to support user contributed modules. The first
      contrib modules are:
        - Weights Viewer – A Graphical tool for examining spatial weights
        - World To View Transform – A class for modeling viewing
windows, used by Weights Viewer
        - Shapely Extension – Exposes shapely methods as standalone functions
        - Shared Perimeter Weights – calculate shared perimeters weights


along with many bug fixes and smaller enhancements.
