Hello,

https://dev-private-review.linaro.org/ has been upgraded to Gerrit
2.10.6. Upgrade went smooth, the only issue is that handful open
reviews there are now in "Merge Conflict" state, as discussed below.
However, I tried to merge a test review with such status and it went
OK. If that won't work, a change need to be rebased and re-pushed from
command line.

To remind, the biggest change in 2.10.x is a new change summary screen.
Every user will be notified about it via popup on first access, linking
to detailed documentation:
https://dev-private-review.linaro.org/Documentation/user-review-ui.html
and offering choice to switch back to classic screen (support for which
is dropped in 2.11, so use your judgement when you want to learn the
new screen - now or later).


Please let me know of any issues seen. If nothing big pops up, we'll
finish 2.10.6 migration next weekend, upgrading https://review.linaro.org
and https://lhg-review.linaro.org as discussed below.


Thanks,
Paul
