v0.2.6

• Added draft version of bi parameter 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 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
