JS Version 1.4.2 Release

Fixes :bug:

hiddenFields Functionality Restored
In v1.4.0, we introduced the concept of hiddenFields within applied filters (and by default, builtin.entityType was hidden from the list of filters). This functionality regressed in v1.4.1; you could neither set hiddenFields, nor was it defaulting correctly when not set. In version 1.4.2, the hiddenFields functionality is now restored.
