hi all,

I'm pleased to announce the 0.8.1 release of pandas. This is
primarily a bugfix release, though it includes a number of useful
new features and performance improvements that make it an
immediate recommended upgrade for all pandas users. Some highlights:

- Vectorized, NA-friendly string
  methods (e.g. series.str.replace('foo', 'bar'))
- Improved plotting support for time series data
- Improved styling capability for DataFrame plots (specifying a
  dict of styles) and plotting one column versus another
- Several new plot types developed as part of GSoC 2012 (see
  http://pandasplotting.blogspot.com/ for on going developments
- Significantly improved parsing performance of ISO8601 datetime strings

Thanks to all who contributed to this release, especially Chang
She and Vytautas Jančauskas. As always source archives and Windows installers
can be found on PyPI.
