+Release Date: 2013-Dec-13
+Bug Fixes:
+- Fixed problem in Elastic Net for 'binomial' family if an 'integer' column was
+passed for dependent variable instead of a 'boolean' column
+- '*' support in Elastic Net lacked checks for the columns being combined. Now
+we check if the column for '*' is already an array, in which case we don't wrap
+it with an 'array' modifier. If there are multiple columns we check that they
+are of the same numeric type before building an array.
+- Fixed a software regression in Robust Variance, Clustered Variance and
+Marginal Effects for multinomial regression introduced in v1.4 when
+output table name is schema-qualified.
+- We now also support schema-qualified output table prefixes for SVD and PCA.
+- Added warning message when deprecated functions are run. Also added a list of
+deprecated functions in the ReadMe.
+- Added a Markdown Readme along with the text version for better rendering on
MADlib v1.4
