## New diagrams in 8.4
|
|
|
|
With version 8.4 class diagrams have got some new features, bug fixes and documentation. Another new feature in 8.4 is the new diagram type, state diagrams.
|
|
|
|
![Image show the two new diagram types](./docs/img/new-diagrams.png)
|
|
|
|
## Special note regarding version 8.2
|
|
|
|
In version 8.2 a security improvement was introduced. A securityLevel configuration was introduced which sets the level of trust to be used on the parsed diagrams.
|
|
|
|
- **true**: (default) tags in text are encoded, click functionality is disabled
|
|
- false: tags in text are allowed, click functionality is enabled
|
|
|
|
Closed issues:
|
|
|
|
⚠️ **Note** : This changes the default behaviour of mermaid so that after upgrade to 8.2, if the securityLevel is not configured, tags in flowcharts are encoded as tags and clicking is prohibited.
|
|
|
|
If your application is taking resposibility for the diagram source security you can set the securityLevel accordingly. By doing this clicks and tags are again allowed.
|
|
|
|
```javascript
|
|
mermaidAPI.initialize({
|
|
securityLevel: 'loose'
|
|
});
|
|
```
|
|
