Is data pushed to MQTT immediately or in batches? I couldn’t find any configuration for this in advanced settings.

Also, what is the topic used for MQTT (is there some common hierarchy level, with different data items on different subtopics, or just everything under the same topic, or what)?

Any update to fully supporting extended headers? Short of bypassing the entire stack I haven’t gotten them to work.

When can we expect the images for fresh installs? My previous update seemed to cause issues with my TMU and I’ve been awaiting a new image for flashing.

And how is the Buster release progressing? Any ETA?
