Is there any document to explain what's the improvement or bugs fixed from 2.2 to 2.4? IHAC use 2.2 during POC and it worked well but when in production environment, we tried 2.4 but could not start the service. but tight project schedule, we moved back to 2.2 which works well but customer want to learn the difference.
MCTB 2.4 has signifiicant performance improvements and some defect fixed over 2.2. There is also a known defect in version 2.2 that can cause CFOD to fail in certain cases, so upgrading to 2.4.0 as soon as possible is important. Make sure the windows service is set to start "Automatic (delayed)". This should fix the start up problem.
