Dear PyMVPA users,

I am glad to announce that we are releasing 0.4.4 version of

So far we have:
  * pushed/tagged sources in git repository
  * uploaded Debian packages into Debian/sid proper
    (should become available later on today)
  * uploaded Debian packages into http://neuro.debian.org
    repository for:
	+ Debian: lenny, squeeze
	+ Ubuntu: jaunty, karmic
  * source tarballs and windows installer available from
    usual location
  * RPM-based GNU/Linux Distributions
	available from OpenSUSE Build Service. See

This is primarily a bugfix release, probably the last in 0.4 series since
development for 0.5 release is leaping forward -- please keep an eye on the
mailing list for the announcement of availability of snapshots of development

Changelog for the release is:

  * New functionality (19 NF commits):

    - :class:`~mvpa.clfs.gnb.GNB` implements Gaussian Naïve Bayes
    - :func:`~mvpa.misc.fsl.base.read_fsl_design` to read FSL FEAT design.fsf
      files (Contributed by Russell A. Poldrack).
    - :class:`~mvpa.datasets.miscfx.SequenceStats` to provide basic
      statistics on labels sequence (counter-balancing,
    - New exceptions :class:`~mvpa.clfs.base.DegenerateInputError` and
      :class:`~mvpa.clfs.base.FailedToTrainError` to be thrown by
      classifiers primarily during training/testing.
    - Debug target `STATMC` to report on progress of Monte-Carlo
      sampling (during permutation testing).

  * Refactored (15 RF commits):

    - To get users prepared to 0.5 release, internally and in some
      examples/documentation, access to states and
      parameters is done via corresponding collections, not from the
      top level object (e.g. `clf.states.predictions` instead of
      soon-to-be-deprecated `clf.predictions`).  That should lead also
      to improved performance.
    - Adopted copy.py from python2.6 (support Ellipsis as well).

  * Fixed (38 BF commits):

    - GLM output does not depend on the enabled states any more.
    - Variety of docstrings fixed and/or improved.
    - Do not derive NaN scaling for SVM's C whenever data is
      degenerate (lead to never finishing SVM training).
    - :mod:`~mvpa.clfs.sg` :

      + KRR is optional now -- avoids crashing if KRR is not available.
      + tolerance to absent `set_precompute_matrix` in svmlight in
        recent shogun versions.
      + support for recent (present in 0.9.1) API change in exposing
        debug levels.

    - Python 2.4 compatibility issues: :class:`~mvpa.clfs.knn.kNN` and
