Breaking Changes
There is no migration necessary for a 3.x database to be written to and read from when upgrading to 4.0.0. However, once new data is written by an Event Store 4.0.0 node the database would be considered invalid/corrupt by a 3.x node.
Projections
We have removed the whenAny function in favour of $any.
