Pandas 0.14.1

I have just upgraded to Pandas 0.14.1.

It was a pain. At first, none of my graphics programs worked. It looks like a change to the API for parsing Microsoft Excel files was the problem. I am not sure whether my previous approach was wrong (but worked serendipitously), or the API was deliberately changed to break old code (an unusual practice for a point release). If someone knows, I'd appreciate something in the comments below.

What follows are the classes I use to upload Australian Bureau of Statistics (ABS) and Reserve Bank of Australia (RBA) data, with the updates to the parsing stage commented.

And yes, I use Python 2.7, not Python 3 (it's what comes with the Apple Mac).
