According to webcam imagery and the impression of one of our friends, mountain guide on Etna, the lava flow at the southern base of the SE crater has likely stopped. We still wait for official confirmation.
However, the recorded volcanic tremor has dropped as well during the past 24-48 hours, suggesting that this is likely indeed the case, thus marking the end of the most recent effusive episode that had started in late November last year.
