Beautiful strombolian activity from at least 4 different crater continues with little changes, dominantly from the two vents of the New SE crater, but also from the central crater (Voragine) and the Bocca Nuova crater located west of the Voragine.
The activity of Bocca Nuova, not usually visible on webcam views or pictures taken from below, was documented a few days ago by Michele Mammino, a regular visitor of the volcano and its eruptions:

The video, taken from the western rim, shows that there is mild strombolian activity from a vent in the western part of the crater, where a cinder cone is currently forming. In addition, there are active hornitos with degassing and occasional spattering further to the east in the crater.
The products of this activity, not visible usually from below, have been filling the crater floor and covering the last winter's lava flows that had been descending from the new cone in the neighboring Voragine crater.
Continuing strombolian activity from several craters

The volcano continues to produce spectacular strombolian-type explosions involving several of its summit craters.
Protagonist of this activity remains the New SE crater with two active vents, followed by less-intense activity at the Voragine and occasionally Bocca Nuova central craters.
At the same time, micro-seismic activity remains elevated. A small swarm of magnitudes at shallow depth beneath the summit region has been detected during the past 24 hours. So far, there have been 15 quakes of magnitudes up to 2.1.
Volcanic tremor stays at high levels, but shows no clear trend. The current activity of Etna seems to be rather stable.
Activity decreases a bit

During the night, volcanic tremor descended a bit (although remains high) and the strombolian activity concentrated at the New SE crater with occasional bursts also from Voragine central crater decreased as well.
Apparently, the configuration of the principal crater of the SE cone has changed recently in a way that many glowing bombs now land on the upper eastern slope of the cone, giving often the impression of short lava flows.
Intense strombolian activity

Europe's most active volcano remains highly active, erupting from at least two of its summit craters: although visibility has been very poor, intermittent clear views allow to see intense strombolian-type activity from the New SE crater and the Voragine central crater.
The latter is less frequent and not as strong as the activity at the protagonist New SE crater. Tremor has been high and showing a steady increasing trend, indicating that magma is currently flowing towards the surface at increased rate.
Whether there will be another paroxysm with lava fountains soon is open to speculation at the moment.

Last night's activity of vigorous and near-constant strombolian explosions from the eastern summit vent of the New SE crater continued to increase, but judging from webcam imagery, it did not quite reach the intensity of previous paroxysms with true lava fountains.
During the most intense phase, starting around 1:45 am local time, a new lava flow was emitted from either the same vent at the summit of the New SE crater or a fissure beneath it, and descended approx. 200-300 m to the flat area at its northeastern base.

Whether or not it might be formally counted as a (weak) paroxysm is up to volcanologists to decide.
Increasing activity, likely heading to another paroxysm

During the past hours, activity from the New SE crater has been increasing significantly and is currently showing intense and near-constant strombolian explosions. It seems very much as if it is heading for another paroxysm in the next hours if not less.
The volcanic tremor signal is also on an increasing trend.
During most of the day, when visibility allowed views, there were small and irregular ash emissions, likely related to smaller explosions from the New SE crater. In the evening, constant glow and intermittent explosions were visible. These have been increasing significantly during the past few hours.
