Web Service or Wrapper Integrations:

Since a new PDFreactor Web Service is introduced with this version, the old Wrapper APIs have been completely overhauled and integrations have to be adapted. Important: The PDFreactor 8 Web Service now requires Java 8 to run. Older Java versions are not supported for the Web Service. The PDFreactor Java Library can still be used with previous Java versions.

Java Library Integrations:

A new PDFreactor Java API has been introduced with which you can transition near seamlessly from and to the new Java Wrapper API. The previous Java API is still available under the com.realobjects.pdfreactor.legacy package, however you are strongly encouraged to migrate to the new API as soon as possible.

Command Line Integrations:

The legacy PDFreactor command line binaries are no longer included in PDFreactor 8 and were replaced with a new Python based command line interface that uses and requires the PDFreactor Web Service. The legacy PDFreactor command line interface can still be used as before by calling java -jar pdfreactor.jar on the command line. The legacy PDFreactor command line is no longer maintained in PDFreactor 8 and some PDFreactor 8 features might not be available using it.
