+MADlib v1.4
+
+Release Date: 2013-Nov-25
+
+New Features:
+* Improved interface for Multinomial logistic regression:
+    - Added a new interface that accepts an 'output_table' parameter and
+    stores the model details in the output table instead of returning as a struct
+    data type. The updated function also builds a summary table that includes
+    all parameters and meta-parameters used during model training.
+    - The output table has been reformatted to present the model coefficients
+    and related metrics for each category in a separate row. This replaces the
+    old output format of model stats for all categories combined in a
+    single array.
+* Variance Estimators
+    - Added Robust Variance estimator for Cox PH models (Lin and Wei, 1989).
+    It is useful in calculating variances in a dataset with potentially
+    noisy outliers. Namely, the standard errors are asymptotically normal even
+    if the model is wrong due to outliers.
+    - Added Clustered Variance estimator for Cox PH models. It is used
+    when data contains extra clustering information besides covariates and
+    are asymptotically normal estimates.
+* NULL Handling:
+    - Modified behavior of regression modules to 'omit' rows containing NULL
+    values for any of the dependent and independent variables. The number of
+    rows skipped is provided as part of the output table.
+    This release includes NULL handling for following modules:
+        - Linear, Logistic, and Multinomial logistic regression, as well as
+        Cox Proportional Hazards
+        - Huber-White sandwich estimators for linear, logistic, and multinomial
+        logistic regression as well as Cox Proportional Hazards
+        - Clustered variance estimators for linear, logistic, and multinomial
+        logistic regression as well as Cox Proportional Hazards
+        - Marginal effects for logistic and multinomial logistic regression
+
+Deprecated functions:
+    - Multinomial logistic regression function has been renamed to
+    'mlogregr_train'. Old function ('mlogregr') has been deprecated,
+    and will be removed in the next major version update.
+
+    - For all multinomial regression estimator functions (list given below),
+    changes in the argument list were made to collate all optimizer specific
+    arguments in a single string. An example of the new optimizer parameter is
+    'max_iter=20, optimizer=irls, precision=0.0001'.
+    This is in contrast to the original argument list that contained 3 arguments:
+    'max_iter', 'optimizer', and 'precision'. This change allows adding new
+    optimizer-specific parameters without changing the argument list.
+    Affected functions:
+        - robust_variance_mlogregr
+        - clustered_variance_mlogregr
+        - margins_mlogregr
+
+Bug Fixes:
+    - Fixed an overflow problem in LDA by using INT64 instead of INT32.
+    - Fixed integer to boolean cast bug in clustered variance for logistic
+    regression. After this fix, integer columns are accepted for binary
+    dependent variable using the 'integer to bool' cast rules.
+    - Fixed two bugs in SVD:
+        - The 'example' option for online help has been fixed
+        - Column names for sparse input tables in the 'svd_sparse' and
+        'svd_sparse_native' functions are no longer restricted to 'row_id',
+        'col_id' and 'value'.
