Installed 9.13.1.2 - initial results (positive)

I am 9 days in. Things seem better with this version of firmware, but there is work to do on the four major issues I have suffered from. I have power cycled but have not done a full factory reset. 

Summary so far:

1. IPv6 - as noted above - had to disable, not working on Apple iPhone and iPad;
2. Flips to cellular when on WiFi - I have had 2 occurrences of this, the first was day two and the second was day 8, so the frequency is much less so far - plus I have been testing and looking for this.
3. Memory creep on Orbis - nothing obvious so far, but I am starting to get suspicious of one satellite 970 (which is the one that crashed, see below) - it has slowly moved from ~605MB used to 630MB. I only check it once a day and mem usage jumps around, but this will become obvious or not in the next 2 weeks.
4. Restarts due to crashes - one unfortunately. I sent the logs in. According to the logs the restart happened overnight about 4 days ago, a kernel panic crash.
