Selection of most important improvements include:
#82: Python bindings missing get/set intensity
#83: Support fractional seconds in the Python bindings
#84: Improve LASPoint::equal
#89: Python liblas.version did not work
#88: liblas-config script to provide library/include locations to software wishing to link to libLAS
#86: las2txt M option allowing the index number of the point to be included in the output
libLAS is a generic GNU autoconf/autotools project, however, and building libLAS is as simple as ./configure;make;make install.
