The short answer
The demo content expansion adds two heroes and more combined-world puzzles. The technical beta is a separate update with settings and compatibility changes.
Content expansion
The Bard and Druid join the demo’s hero set. The official post also adds overworld areas and content showing worlds merging. A guide written for the earlier demo may therefore be incomplete even when its individual observations remain useful.

Technical beta
The later technical post changes performance options and audio controls. It does not establish that every player is on the beta; record your branch when comparing behaviour with a guide or reporting a bug.

Next verification priorities
The full release will require a fresh room census, repeatable starting states, platform checks and save-transfer testing. Until those exist, the wiki’s named abilities and setup advice remain limited to the linked announcements.
