This deliverable presents the work of PARTHENOS Work Package (WP) 8 “Communication,dissemination and outreach” during the final year of the project (May 2018 – April 2019) and its half year extension (May – October 2019). The document builds on four earlier deliverables; D8.2 Initial Communication Plan was produced in July 2015 and laid the foundation for our communication, dissemination and outreach strategy. While constantly adjusting our approach to the evolving project status, three updated versions to that document were produced: the first time in July 2016 – D8.3 First Year Communication Report, and Updated Communication Plan – the second time in July 2017 – D8.4 Second Year Communication Report, and Updated Communication Plan – and the third time in July 2018 – D8.5 Third Year Communication Report, and Updated Communication Plan. Whereas the Initial Communication Plan presented an overall dissemination and communication strategy, and provided a detailed plan of relevant activities for the project’s first year, the First-, Second- and Third Year Communication Reports reflected on the implementation of the Initial Communication Plan during the project’s first, second and third twelve month periods, proposed minor corrections to the overall strategy, and set out our plans for each oncoming year.
