Now you get another alternative to generate live reports and keep historic data: the DSL now includes graphiteListener. Check more details in the new user guide section.
Thanks to @Ioiss for requesting this.
Additionally, now is simpler to make simple pauses using the new threadPause element. You can check the updated user guide section.
Finally, you can now use JMeter expressions in constantTimer which allows you to do more powerful stuff with the timer.
Thanks to @lyshchyk and @FakeLogin for asking about these features.
