+- **[ BREAKING ] Main namespace to include is now `datascript.core`, not `datascript`**
 - [ BREAKING ] Old `datascript.core` (internal namespace) was renamed to `datascript.db`
+- [ BREAKING ] `datascript.shim` (internal namespace) was renamed to `datascript.arrays`
 
-Motivation: Usage of top-level namespaces is discouraged and even generates a warning in CLJS. This would’ve happen sooner or later anyways. 0.13 seems like a great number for this sort of release.
+Motivations:
 
-Migration path: just change `(require '[datascript :as d])` to `(require '[datascript.core :as d])` and you’re good to go.

+Beta quality. Most of the features done, expecting some API polishing (breaking) and performance optimizations. No docs at the moment, use examples & Datomic documentation.
 
 The following features are supported:
