Seems to be done: http://repo1.maven.org/maven2/io/oasp/java/oasp4j-bom/2.6.0/

[hohwille]

Seems as also the documentation was merged: https://github.com/oasp/oasp4j/wiki/guide-service-client

Publishing most probably not complete (I get version 2.3.0 here - strange): https://oasp.github.io/assets/PDF/OASP4J.pdf However, from the wiki point of view everything is properly prepared: https://github.com/oasp/oasp4j/wiki/OASP4J

[AbhayChandel]

Done.

We still have version 2.3.0 of the documentation published: https://oasp.github.io/assets/PDF/OASP4J.pdf Also 2.6.0 is not listed here: https://oasp.github.io/oasp4-j
