It documents everything that has changed. Several things will break old code as indicated.
There are several options for keeping old code working: 1) Use the numpy.oldnumeric compatibility layer which keeps the same definitions and defaults as Numeric 2) Use conversion tools (like the recently added fix_default_axis) tool to automatically insert axis=0 arguments in all code where it is not present (or to automatically change the import to oldnumeric). For the future, you must specify which axis you mean for a Nd array or the code will assume you meant to work over the entire N-d array. We all recognize this is a pain to change. That's why the backward compatibilty options are avaiable and the tools have been written. Believe me, I know what a pain it is. I have had to keep SciPy and Matplotlib working with all the changes to NumPy. -Travis ------------------------------------------------------------------------- Take Surveys. Earn Cash.
