+# [0.7.2](https://github.com/briebug/ngrx-auto-entity/compare/0.7.2...0.8.1-beta.1) Beta (2022-04-05)
+
+Updated state builders to build all state functionality "on-demand" to limit memory footprint when
+lots of entities are used. This aligns selectors, facades, etc. with the way actions were implemented
+when they were introduced to the state builder. Selectors for any given entity are only created
+if they are accessed (i.e. destructured from the object returned by `buildState`), and the same goes
+for facades. 
+
+Performed a major internal refactor of the auto-entity reducer in order to break down the single monolithic
+reducer into a more modular design. Each set of related actions, such as loadAll, create, editing, selections,
+etc. have their own corresponding reducer. Actions are now mapped to the appropriate reducer through a 
+centralized mapping for action-to-reducer routing.
+
+These changes are internal, and should not present any breaking changes to the public API. That said,
+the changes are fairly extensive, and care should be used until 0.8 is officially released.
