-STABLE RELEASE
+********************************************************************
+
+        The libSBML source code has moved to GitHub.
+            (https://github.com/sbmlteam/libsbml). 
+
+The stable branch reflects the latest released code. The development 
+branch is the main branch and we encourage users to create and 
+submit pull requests against this branch. We are no longer 
+maintaining a separate repository for experimental code for as yet 
+unfinished packages. 
+
+Please use the GitHub issue tracker to file any reports or submit a
+fix and do a Pull Request.
+
+We will gradually move away from SourceForge, but for this release 
+code will be available from both SourceForge and GitHub. 
+
+
+
+* Addition of support for the SBML Distributions package
+
+  - Now that the first official version of the specification for the
+    SBML Level 3 Distributions package is available, the libSBML API for
+    'distrib' is now included in the stable release of libSBML.  This
+    means that all prebuilt binaries for the stable release will
+    include the 'distrib' package code. The src archive containing
+    libSBML core code will continue to be available, with additional
+    archives of the individual package code.
+
+    NOTE: The libSBML GNU make-based build system has not been updated
+          for packages. Thus, to build from src, it is necessary to
+          use the CMake build system.
 
 * New features
 
   - Functions get/set/isSetMath have been added to the SBase class.
     These do not allow interacting with a non-existant <math> element 
     but may facilitate using more generic functions.

 * Bug fixes
 
+  - There was a memory leak introduced in the SWIG wrapper. Thanks to  
+    Fabian Fröhlich for spotting and fixing this.
+
+  - The SBMLNamespaces class was being leaked in a number of places, 
+    these have now been plugged. 
+
+  - The MathML to infix parser was also leaking memory. Thanks to  
+    Liam Keegan for spotting and fixing these. 
+
+  - The validation code detecting assignment cycles was incorrectly 
+    including local parameters within its search. These have now 
+    been removed from the relevant code. 
+
+  - Conversion code was failing to detect when a local parameter used 
+    the 'id' of a speciesReference which is allowed in SBML Level 3. 
+    These can be converted to SBML Level 2 and the code has now been
+    corrected so this conversion will take place. 
+
   - The L3 infix parser has been improved to recognize the use of a 
     name without parentheses as a misused function name or a csymbol,
     if appropriate.
