Just got a notification that I'm getting upgraded to BMS 3015 (which I had been putting off). I see from the release notes that there's now also a new firmware A309 (from May 16) which I don't think I've seen mentioned. Anyone tried it ? (Not that I guess I'll get much choice in whether it gets installed with 3015.)

similar description to G2 915.
(Their use of "optimise" in the release notes does amuse me a bit.)
My system was provisioned on 309, it seems to be doing okay so far. Came out of battery calibration without assistance and has been stable on the connectivity & into Home Assistant.
Yes, I updated to 309 last week.
It took 20-25 mins but has been fine. just stopped at 88% for a worrying amount of time.
battery now discharges to 4%.
I have just upgraded to D0.309-A0.309 with no issues, it took about 15 minutes
Just upgraded to D0.309-A0.309. Mine also had the progress bar stick at 88% complete, however, after waiting a while I re-loaded the page and it cleared. The inverter appears to be running normally and the software version shows as updated so all appears good.
