Magnolia 6.2.35 known issues
RSS Aggregator module
The Community Edition (CE) POM file contains 2.6.6-SNAPSHOT for rssAggregatorVersion. The RSS Aggregator module version bundled with Magnolia 6.2.35 should be 2.6.5. If you create a custom webapp for either Magnolia CE or DX Core, you must update this version dependency for a successful webapp build. Updating the version manually in this way is a workaround solution, and Magnolia 6.2.36 will fix the issue.
