I noticed that version 2.5.0 introduced a change in how the servlet context is accessed for the content viewer. Since we have a custom content viewer, we needed to make some updates due to the changes under NIFI-14657 [1].
Would it be possible to add a note about the removal of Spring Boot in the content viewer (and custom extensions) to the migration guidance for 2.5.0 [2]? I think this would be really helpful for others making similar updates. Thanks, Mark [1] https://issues.apache.org/jira/browse/NIFI-14657 [2] https://cwiki.apache.org/confluence/display/NIFI/Migration+Guidance
