+
+### Public API
+
 * fixed pretty printing of function values, [#509](https://github.com/metosin/malli/pull/509)
 * fixed `:function` lenses
 * fixed arity error in `m/function-schema`
 * add localized error messages for all type-schemas
+* support for Lazy EntrySchema parsing
 
 ### Extender API
 
 * `m/walk-leaf`, `m/-walk-entries` & `m/-walk-indexed` helpers
+* new `m/Cached` protocol Schema can support for memoization of `-form`, `-validator`, `-explainer` and `-parser`
+* **BREAKING**: `m/EntrySchema` replaces `m/MapSchema` with new `-entry-parser` method
+* **BREAKING**: (eager) `m/-parse-entries` is removed, use (pluggable) `m/-entry-parser` instead
+* new `m/EntryParser` protocol
