At last, after months of inactivity, I pushed out a new release of [_DataMatrix_](http://www.dennogumi.org/projects/datamatrix). Although the version bump is small (0.8) there are a lot of changes since last releases. The most notable include:

  * Ability to apply functions to elements of the matrix
  * Ability to filter rows by column contents
  * Ability to transpose rows with columns
  * An option to load text files produced by R (which are, by design, broken)
  * Removed the getter for columns, using dictionary-like syntax directly
  * A lot of bug fixes

The download links on [the project page](http://www.dennogumi.org/projects/datamatrix) have been updated, along with [the documentation](http://www.dennogumi.org/doc/datamatrix/).  Also, there is another change, because from now on the official Git repository [is hosted on gitorious.org](http://gitorious.org/datamatrix/datamatrix), and no longer on github, because gitorious (the software) is also free, while github.com's is not. It's mainly a philosophical issue (the same that prompted me to switch from twitter to identi.ca). 

Also, from today _DataMatrix_ is also officially hosted on the [Python Package Index](http://pypi.python.org/pypi/datamatrix/0.8) (with the name "datamatrix"), meaning that you can use easy_install to quickly install it.

If you use this module, let me know what you think (including bugs, if you find them).
