Jackson 2.10.0.pr3 -- the last pre-release version -- now out. Help with testing needed!

[Tatu Saloranta]

As per title, I pushed out 2.10.0.pr3 last night, and with Pj's help,
Scala module is out too.

The plan is to release actual official 2.10.0 by end of September
(partly since there's new Spring Boot version planned for mid-October,
so it could get 2.10.0), and I consider that solid deadline, not just
aspirational.
Given this, it would be great if community members could try out if
systems that are using Jackson 2.9.x would pass regression test suites
with 2.10.0.pr3; and if not, report problems they find. In the past
there have been a few blocking issues for .0 releases, and it'd be
great to reduce that risk.

And if you do end up doing any kind of testing, verification, it would
be good to hear -- not just bug reports but in plausible case of
"everything still working as before", feel free to drop note to saying
that.

Release note for 2.10 in general are here:

and list (most of the) changes, as well as compatibility changes,
observed problems with pre-releases.
