## 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.
