The 3.7.0 release is being VOTE'd on at the moment on the dev@jena list:
https://lists.apache.org/thread.html/a5139d2c560b4b5ce161f8440d4a2cdb733e291f52f355593ef33e69@%3Cdev.jena.apache.org%3E
(being Easter, it might be slower than usual.)
which includes links to the proposed www.apache.org/dist/jena area and
the artifacts to send to maven central.
The documentation is on http://jena.staging.apache.org/
As we use the maven release plugin, the version moves to the next one as
the proposed release is built.

According to latest commit, the Jena release is almost there :

and jena version is already "3.8.0-SNAPSHOT" .

The development community is heading towards Jena 3.7.0 (no specific date
- as ever, it has to fit around the volunteers time).
We'd like to encourage you to test it before the release using the
development code and builds. Drop over to dev@.
There is lots in this release, much more than listed here, but areas that
might be worth you investigating and testing include:
== Java9: Running on a Java9 platform is supported
Language requirement remain Java8. More below.
== SPARQL: Evaluation change
JENA-1507: Changes to GROUP BY when the WHERE pattern has no results.
== Feature
JENA-1461: Allow ARQ custom functions to be written in JavaScript
Draft documentation:
http://jena.apache.org/documentation/query/javascript-functions.html
== API
This release is not binary compatible (NB Releases are not guaranteed to
be binary compatible nor mix-and-match versions of jars).
This time there are specific API changes:
JENA-1389: Return `this` rather than `void` from Dataset
JENA-1495: PR#368 "Return Model from PrefixMapping methods"
** Java9
Java8 is the current LTS version of Java and receives security updates.
The next LTS is Java11. [Sched]
[Sched] http://www.oracle.com/technetwork/java/eol-135779.html
There are different cases for running with Java9:
[1] Run on a Java9 JVM
[2] Build using Java9 JDK, output Java8 class files.
[3] Java9 required - language features and runtime library
[4] Java9 modules
[1] at Jena 3.7.0, running with a Java9 platform (except jena-elephas) is
supported.
[2] at Jena 3.7.0, running maven (3.5.0 or later) using Java9 to produce
Java8 bytecode is supported (except as noted). We now run a Jenkins job
daily to check this for the main jars.
[3] The project has no current plans to require a Java9 language runtime.
The language requirement is still Java8.
[4] Jena jars can work as automatic modules but Jena itself does not
provide a "modules" version. Proper migration needs all the dependencies to
be modules, and also has implications on the upstream. Contribution and
discussions are welcome!

And note: Java 9 is obsolete March 2018, as soon as Java10 comes out.

Notes:
jena-elephas depends on Hadoop that depends on jdk.tools which is not
available in Java9.
