On behalf of the PySAL development team, I'm happy to announce the
official release of PySAL 1.4.

PySAL is a library of tools for spatial data analysis and
geocomputation written in Python. PySAL 1.4, the fifth official
release of PySAL brings the following key enhancements:

   -  spatial regression (spreg):
        - Integration of scipy.sparse structures in all the regression classes
        - Probit
        - Probit with diagnostics for spatial effects

  -  exploratory spatial data analysis (esda):
        - Generalized Gamma statistics for spatial autocorrelation

  -  spatial dynamics (spatial_dynamics):
        - O(n log n) algorithm for spatial tau (spatial rank correlation)
        - LISA Markov transitions and tests for spatial dynamics

  - computational geometry (cg) and spatial networks
        - efficient point to nearest LineSegment search
        - generate network topology from shapefiles
        - utilities for interfacing with networkx
        - integration of network cluster code (beta)

among the 155 commits and bug fixes since the last release, 6 months ago.
