 ## Changelog
-### 1.0.0
-This is a complete rewrite of the 0.5 version of Yjs. Since Yjs 1.0 it is possible to work asynchronously on a persistent database, which enables offline support.
+
+### 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.
+
+### 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.
 * Switched to semver versioning
 * Requires a promise implementation in environment (es6 promises suffice, included in all the major browsers). Otherwise you have to include a polyfill
 * Y.Object has been renamed to Y.Map
