 Bi parameter generation
 Added testing
-Improved performance of activity generation
+ -Added tests for data integrity (ids are valid, unique, etc.)
+ -Added tests for interactive workload parameter bindings
+ -Added tests for update streams proper sorting
+ -Added a test script for automatic test of determinism for pseudo-/distributed execution modes. This script must be manually executed outside the testing framework
+Improved performance of activity generation.
+ -Execution flow within activity generation is changed to shape things better for the java compiler
+ -Improved factor storage, releasing used memory when factors are no longer needed. This makes activity generation to scale close to linear with respect to the network's size
 Improved performance of sorting update streams and serialization
-Added option to turn on/off printing the endline separator on csv serializers
-Added possibility to override the way weights of edges are computed
-Added the possibility to override the way dates and datetimes are formatted
-Added graphalytics extended serializer
+Added the option to turn on/off printing the endline separator on csv serializers
+Added the option to override the way weights of edges are computed
+Added the option to override the way dates and datetimes are formatted
+Added the graphalytics extended serializer including weights and timestamps
+Added the option to override the way text of posts and comments is generated
+Improved tunable clustering coefficient edge generation
+Integrated parameter generation within java execution
+Added the option to enable/disable the sorting of persons prior to serialization (Enabled by default)
+Improved the way Exceptions are handled
+Critical Bug fixing
+ -Fixed a bug that caused corrupted data when a reducer failed to execute and hadoop retried its execution in another node
+ -Fixed a bug with factors generation, causing some queries not to produce valid parameters
+ -Fixed a bug causing message lengths to go beyond the maximum size of 2000 characters
+ -Fixed bugs at ttl serializer
