+
+0.7
+===
+
+scikits.learn 0.7 was released in March 2011, roughly three months
+after the 0.6 release. This release is marked by the speed
+improvements in existing algorithms, like k-Nearest Neighbors and
+K-Means algorithm and by the inclusion of an efficient algorithm for
+computing the Ridge Generalized Cross Validation solution. Unlike the
+preceding release, no new modules where added to this release.
+
+Changelog
+---------
+
+ - Performance improvements for Gaussian Mixture Model sampling [Jan
+ Schlüter].
+
+ - Implementation of efficient leave-one-out cross-validated Ridge in
+ :class:`linear_model.RidgeCV` [`Mathieu Blondel`_ ]
+
+ - Better handling of collinearity and early stopping in
+ :func:`linear_model.lars_path` [`Alexandre Gramfort`_ and `Fabian
+ Pedregosa`_ ].
+
+ - Fixes for liblinear ordering of labels and sign of coefficients
+ [Dan Yamins, Paolo Losi, `Mathieu Blondel`_ and `Fabian Pedregosa`_ ].
+
+ - Performance improvements for Nearest Neighbors algorithm in
+ high-dimensional spaces [`Fabian Pedregosa`_ ].
+
+ - Performance improvements for :class:`cluster.KMeans` [`Gael
+ Varoquaux`_ and `James Bergstra`_ ].
+
+ - Sanity checks for SVM-based classes [`Mathieu Blondel`_ ].
+
+ - Refactoring of :class:`neighbors.NeighborsClassifier` and
+ :func:`neighbors.kneighbors_graph`: added different algorithms for
+ the k-Nearest Neighbor Search and implemented a more stable
+ algorithm for finding barycenter weigths [`Fabian Pedregosa`_ ].
+
+ - Documentation improvements: Added
+ :class:`pca.RandomizedPCA`. :class:`linear_model.LogisticRegression`. Also
+ added references of matrices used for clustering and other fixes
+ [`Gael Varoquaux`_, `Fabian Pedregosa`_, `Mathieu Blondel`_,
+ `Olivier Grisel`_, Virgile Fritsch , Emmanuelle Gouillart ]
+
+ - Binded decision_function in classes that make use of liblinear_,
+ dense and sparse variants, like :class:`svm.LinearSVC` or
+ :class:`linear_model.LogisticRegression` [`Fabian Pedregosa`_ ].
+
+ - Performance and API improvements to
+ :func:`metrics.euclidian_distances` and to
+ :class:`pca.RandomizedPCA` [`James Bergstra`_ ]
+
+ - Fix compilation issues under NetBSD [Kamel Ibn Hassen Derouiche]
+
+ - Allow input sequences of different lengths in :class:`hmm.GaussianHMM`
+ [`Ron Weiss`_ ]
+
+ - Fix bug in affinity propagation caused by incorrect indexing [mxf]
