+Announcement: scikits-image 0.4
+===============================
+
+We're happy to announce the 0.4 release of scikits-image, an image processing
+toolbox for SciPy.
+
+Please visit our examples gallery to see what we've been up to:
+
+   http://scikits-image.org/docs/0.3/auto_examples/
+
+Note that, in this release, we renamed the module from ``scikits.image`` to
+``skimage``, to work around name space conflicts with other scikits (similarly,
+the machine learning scikit is now imported as ``sklearn``).
+
+A big shout-out also to everyone currently at SciPy India; have fun, and
+remember to join the scikits-image sprint!
+
+This release runs under all major operating systems where Python (>=2.6 or
+3.x), NumPy and SciPy can be installed.
+
+For more information, visit our website
+
