Phase 5: the April 18, 2024 major test
The April 15 announcement scheduled a four-day test beginning April 18, 2024. Those dates have passed. The event brought together features developed during Phase 5 rather than introducing an open-ended play period.
What the test brought together
Families and Homesteads shared the stage with seasons, rain and snow. Dire Ravens guarded Deadwood, Bronze equipment filled an earlier progression gap, and Windmills offered another power source. The 
Heating Vat processed materials using water and fuel. Later announcements continue to revise these systems, so this post is best read as the state of that test.
