What's cooking in the Eclipse Platform Project

Presentation from EclipseCon Europe 2019

The Eclipse Platform Project is alive and kicking! Let's recap what happened during the last year of development.

First we have a look at the stats: How is the contribution activity, who is working on the project. What's the impact of the new quarterly release schedule on the project? Why it was important that the Gerrit merge strategy was changed?

Next a look at the areas where has been worked on. Especially the value that non-functional changes have: Mass cleanups, removals, performance. But also features, especially usability changes.

Finally a look into the future and a shout out that it is important to attract contributors to work together on the platform.

17. itemis.com SEMANTIC VERSION UPDATE HELL
18. itemis.com SEMANTIC VERSION UPDATE HELL ! Semantic versioning policy forces bundle/feature version updates for each project touched by changes within a release cycle ! Quarterly releases improve the speed for version updates ! Different change policies ! With the Gerrit change ! With separate change ! Candidates for conflicts

Experimental feature
