BMS update- portal showing?

I’m currently on 3015. I have twin AC3/8.2 setup. No EMS but one is planned. 3017 is available on my portal. I’ve put off upgrading for the notes people have made on limited charge/discharge speed etc.

I have seen 3018/19 mentioned and now 3020 (if self load), now my question is if 3018/19 have been mentioned, does 3017 need to be loaded first for these to be available by the portal? (I’m aware that 3020 isn’t available via the portal yet)

No. Can go to 3020 if you wish.

Portal releases take time. So I took this decision mention these can always be side loaded manually.
The download resources page is populated as soon as they are tested. So is a much faster way.
