Tree/Routine Export ConsistencyWhen exporting a Tree or Routine, the XML definition has been normalized and will export in a consistent format. Previously even if no changes were made to a Tree or Routine, whitespace and new lines were added/removed and it appeared as though there were changes when comparing to a previous version.KT-1016
Performance ImprovementsChanges the way in which work is processed within the engine. Instead of "sleeping", the engine will process new work if it exists. Additionally, work that is not part of a loop will now be prioritized and completed before work that is part of a loop contextKT-1016, KT-1019

Web Server Recommendations

ItemRecommendation
Web Application ServerTomcat 7.0.77+
Web Server Heap MemoryMinimum 512MB (-Xms512m)
Maximum 1024MB (-Xmx1024m)

The recommended properties can be added to the JAVA_OPTS environment variable for the web server. If running a Tomcat server, the CATALINA_OPTS environment variable should be used instead.

  • If running a Tomcat server in a Linux environment, the properties should be added to the <tomcat>/bin/setenv.sh file. Simply create the setenv.sh file if it doesn't exist, and ensure the file has execute permission (chmod +x setenv.sh).
    • export CATALINA_OPTS="-Xms512m -Xmx1024m"
  • If running a Tomcat server as a Windows service, the properties must be added to the Windows registry. The recommended way to do this is to use the Tomcat Monitor application.
    • The initial memory pool setting is the same as the -Xms property, so set this to 512 MB.
    • The maximum memory pool setting is the same as the -Xmx property, so set this to 1024 MB.
  • If running a Tomcat server manually from a Windows command prompt, the properties should be added to the <tomcat>/bin/setenv.bat file. Simply create the setenv.bat file if it doesn't exist.
    • SET CATALINA_OPTS="-Xms512m -Xmx1024m"
  • If running any other web server, consult the web server documentation for setting Java options.
