What's New in the Eclipse Platform Project (EclipseCon 2020)

This is a wrap up of what has happened in the Eclipse Platform Project from last year's EclipseCon (Eclipse 2019-09) till EclipseCon 2020 and also current challenges the Eclipse Platform team is working on.

The talk is complementary to other talks given at EclipseCon that focused on aspects like JDT, Java Support, Build, or Performance.
