## Project Activity:
Jena version 4.2.0 was released 2021-09-12. It fixed CVE-2021-39239,
which was discovered by the team, and affects all version 4.1.0 and earlier.
The release was not just about a CVE fix. The release included a new
component, a data validation engine for the ShEx language to go
alongside the SHACL engine; and also support for reading JSON-LD 1.1
using an external 3rd party library. JSON-LD 1.1 is used by some IOT
device and service descriptions.
During the release checking, a problem was discovered in the OSGi bundle
related to the new dependencies for JSON-LD 1.1 handling. The project
dropped the OSGi convenience binaries, and a discussion has started
about retiring them. The development community no longer has the skills,
nor interest, necessary to maintain their production. Contact with known
downstream open source projects, and a message to users@ has not
produced any concern.
Jena has a process for retiring modules - delete in git, record the last
git commit with the code in case some interest emerges and will maintain
the module.
## Community Health:
Activity seems normal. Some of the figures are slightly skewed because
one PR had 48 commits which is unusual for Jena.
The dev@ list is also the destination of JIRA email and is otherwise
quite quiet. The speed of evolution of the project is down to developer
time.
The users@ is active and the main support channel.
