After a year of the v1, it's finally time for the next major release of zundo. The goal is to create a smaller bundle size, have an easier API, and improve type correctness.

All new work is being done in packages/zundo

Here is a checklist that is required before v2 can be released:

• Support zustand v4
• modify zustand types to support temporal object
• create temporal factory function (undo, redo, clear, pastStates, futureStates)
• persist option (to replace include and exclude)
• add steps param to undo and redo
• Add option to pause and resume history tracking (pause(): void, resume(): void, state: 'tracking' | 'paused')
• Add optional historyDepthLimit as limit
• Add option to pass equality function to save states (rather than bundling lodash/isEqual)
• Add option to provide a callback when state is saved in temporal store. onSave
• Add handleSet middleware. Add option to set coolDownTime. Maybe we can allow the user to pass in a function rather then writing it ourself? Debounce vs Throttle
• chained middleware support
• update readme IN PROGRESS
• dev tools support IN PROGRESS

Future versions of v2

• create nicer API, or a helper hook in react land (useTemporal). or vanilla version of the it
• Allow alternative storage engines for past and future states
• See if it canUndo and canRedo
• Set initial history, past and future states
• create jump method that takes an integer
• create a present object that holds the current state? perhaps
• support history branches rather than clearing the future states
• Pass middleware to temporal store
• store state delta rather than full object
