Quick note: I released 3.0.0-rc10 yesterday. Accumulated changes in
3.0.0 can be found from:

https://github.com/FasterXML/jackson/wiki/Jackson-Release-3.0

although not fully separated by Release Candidates.

The important thing is that we are next hoping to release the Official
3.0.0 Jakson -- and ideally by next weekend. And for that to go
smoothly, it would be really REALLY great if everyone with time &
interest to help could check how this release candidate works
(assuming you have code, tests etc that work against Jackson 3.0
components).
We still have some time to

(a) fix critical issues found
(b) if need be, make API changes, additions
(c) if we must, release one or more RCs for further validation

but the time window is closing (we are working with the Spring team to
get 3.0.0 GA ready for Spring 7!).

So. Any and All help with testing of Jackson 3.0.0-rc10 is warmly appreciated.

ps. while you can manage your dependencies however you want, we
recommend use of "jackson-bom"
(https://github.com/FasterXML/jackson-bom):

<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.fasterxml.jackson</groupId>
<artifactId>jackson-bom</artifactId>
<version>3.0.0-rc10</version>
<scope>import</scope>
<type>pom</type>
</dependency>
</dependencies>
</dependencyManagement>
