v4.0.0

This version introduced a number of changes into the codebase resulting in a much more performant experience for the general user as well as adding increased support for adapting the responsive state to fit your particular use case.

StoreEnhancer

• calculateStateInitially is now calculateInitialState
• performanceMode is now default (no more throttled handler or associated options)

Reducer / Responsive State

• no more height/width (see README for instructions on migration forward)
• Added is field to responsiveState (browser.is.small <=> browser.mediaType === "small")
• ReducerFactory now accepts options as second argument (after breakpoints)
• infinityType argument is now the infinity field of the argument
• user-defined fields can be added to the responsive state with the extraFields option which is defined as a function that takes the current responsive state and returns the new fields to add (is spread over old state so user could also overwrite values if they wanted)
