-* New Exported funtions: rrd_lcd, rrd_reduce_data, rrd_cf_conf and rrd_list
+* New Exported functions: rrd_lcd, rrd_reduce_data, rrd_cf_conf and rrd_list
* rrd_list support for perl and python binding
* all new and much more complete python bindings working on both python 2.6+ and 3.3+
* extended documentation in rrdlib.pod
--------
* segfault on CDEF:x=

-* make vname nameing rules more liberal and more in line with 1.4
+* make vname naming rules more liberal and more in line with 1.4
* Fix recursive directory creation in rrdcached on FREEBSD
* Fixed compilation when there's no sigwaitinfo
* the optional argument :skipscale allows for a LINE or AREA instruction to be
excluded from having an effect on the scaling of the graph
-* TRENDNAN is now working properly and als not crashing anymore
+* TRENDNAN is now working properly and also not crashing anymore
* Added a no-op string positioning combo "\." this allows to write

In order to build the static freetype lib enter the freetype base directory
and type 'make'. If everything is fine a message appears that gcc is detected,
and that you should again type 'make'. Follow that in order to build freetype.

traceback when they can not make sense out of the arguments you fed them.
However, you can capture and handle the errors yourself, instead of just
letting the program abort, by calling the module functions through Lua
