Release Notes

jwtk/jjwt

v0.8.0

Compare Source

This is a minor feature enhancement, dependency version update and build update release. We switched from Jacoco to
OpenClover as OpenClover delivers a higher quality of test metrics. As an interim measure, we introduced a new
repository that has an updated version of the coveralls-maven-plugin which includes support for Clover reporting to
Coveralls. Once this change has been merged and released to the official coveralls-maven-plugin on maven central,
this repository will be removed. The following dependencies were updated to the latest release version: maven
compiler, maven enforcer, maven failsafe, maven release, maven scm provider, maven bundle, maven gpg, maven source,
maven javadoc, jackson, bouncy castle, groovy, logback and powermock. Of significance, is the upgrade for jackson as
a security issue was addressed in its latest release.

An addClaims method is added to the JwtBuilder interface in this release. It adds all given name/value pairs to
the JSON Claims in the payload.

Additional tests were added to improve overall test coverage.
