 ## Changelog
 
+### 10.0.0
+
+* Support for more complex types (a type can be a composition of several types)
+* Fixes several memory leaks
+
 ### 9.0.0
-There were several rolling updates from 0.6 to 0.8. We'll now follow the semver versioning scheme. This is all what this jump from 0.8 to 9.0 is about.
+There were several rolling updates from 0.6 to 0.8. We consider Yjs stable since a long time, 
+and intend to continue stable releases. From this release forward y-* modules will implement peer-dependencies for npm, and dependencies for bower.
+Furthermore, incompatible yjs instances will now throw errors when syncing - this feature was influenced by #48. The versioning jump was influenced by react (see [here](https://facebook.github.io/react/blog/2016/02/19/new-versioning-scheme.html))
+
 
 ### 0.6.0
 This is a complete rewrite of the 0.5 version of Yjs. Since Yjs 0.6.0 it is possible to work asynchronously on a persistent database, which enables offline support.
