Progress last Quarter

Progress last Quarter

• CBNG 3.9.0 released with new Jenkins-based release server
  • Start difficulty for Eclipse users: release command failed due to missing certificates
    => solution: switch to standard controls java distribution on local disk
  • Resolved: incorrect tag name in multi-project builds & setting the DISPLAY for GUI tests

• CBNG 3.9.2 now fully supports SNAPSHOT releases
  • SNAPSHOT = industry standard for development releases
  • Useful for cross-project builds with multiple branches in parallel
