+This is a minor release: It combines bug fixes and new features.
+ Changes to existing features were made in a backwards-compatible
+ way such as to allow drop-in replacement of the v3.4.1 JAR file.
+  
+Most notable among the new features are:
+ getQuadraticMean method added to DescriptiveStatistics SummaryStatistics
+ which calculates the root mean square, and a way to build polyhedrons sets
+ from list of vertices and the facets they belong too. There have been
+ numerous bug fixes. See below for a full list.
+  
+The minimum version of the Java platform required to compile and use
+ Apache Commons Math is Java 5.
+  
+Users are encouraged to upgrade to this version as this release not
+ only includes bug fixes but also deprecates numerous classes and
+ methods that will be deleted from the next major release (4.0).
+  
+  Caveat:
+  1. The implementation of the BOBYQA optimization algorithm is in alpha
+  state (cf. MATH-621): Many code paths are untested, and we are looking
+  for volunteers to improve the code readability, robustness and performance
+  and to extend the unit tests suite.
+  2. A few methods in the FastMath class are in fact slower that their
+  counterpart in either Math or StrictMath (cf. MATH-740 and MATH-901).
