[SciPy-User] ANN: Scipy 0.13.1 release

ralfgommers
Hi,

I'm happy to announce the availability of the scipy 0.13.1 release. This is a bugfix only release; it contains several fixes for issues in ndimage. Thanks to Pauli Virtanen and Ray Jones for fixing these issues quickly.

Source tarballs, binaries and release notes can be found at http://sourceforge.net/projects/scipy/files/scipy/0.13.1/.

Cheers,
Ralf



==========================
SciPy 0.13.1 Release Notes
==========================

SciPy 0.13.1 is a bug-fix release with no new features compared to 0.13.0.
The only changes are several fixes in ``ndimage``, one of which was a serious
regression in ``ndimage.label`` (Github issue 3025), which gave
incorrect results in 0.13.0.

Issues fixed
------------

- 3025: ``ndimage.label`` returns incorrect results in scipy 0.13.0
- 1992: ``ndimage.label`` return type changed from int32 to uint32
- 1992: ``ndimage.find_objects`` doesn't work with int32 input in some cases

Ralf,
   Unfortunately, the scipy 0.13.1 release has introduced two new failures on the
x86_64-apple-darwin11 target...

whereas both x86_64-apple-darwin12 and x86_64-apple-darwin13, there are no failures.

OK (KNOWNFAIL=114, SKIP=203)

What darwin releases was this update tested on?

Thanks Ralf et al. for more great work!

What's the plan for OS-X binaries? It would be great to have those up sooner than later...Can I help?
