2.12.0-rc1 is out now, including Scala module (thanks to @pjfanning).

At this point help with integration/compatibility testing would be appreciated.
And in fact there has already been testing, and we have 2 reports of
regressions to address:

* https://github.com/FasterXML/jackson-databind/issues/2878 --
source-compatibility wrt removing exception (sent another email on
this)
* https://github.com/FasterXML/jackson-databind/issues/2880 -- removal
of PropertyNamingStrategy instances deprecated in 2.7 breaks
compatibility with 2.6

and I will likely revert changes to resolve both.

There are also a few issue in-flight so there is a good change we
might want to have 2.12.0-rc2 before final 2.12.0, but regardless of
that,
I think that 2.12.0 final will not be out until early November.

ps. Relatively new repo --
https://github.com/FasterXML/jackson-integration-tests/ -- is a new
place where we can start adding some of compatibility tests, both
across Jackson components (which can not go in other repos) and in
some cases between Jackson and other projects.
