## Cross-component updates

### [Li.Fi](http://Li.Fi) widget integration

The new [Li.Fi](http://Li.Fi) integration lets you swap assets on different chains to BOB on Polygon directly from the zkBob application. The widget shows the best routes and automates the swapping and bridging processes. The example below walks through using the Li.Fi widget to swap MATIC for BOB.

### Support improvements with Support ID

We’ve made it easier to get help even when there are no on-chain traces remaining. A unique support ID is now displayed in app footer or if you receive an error when submitting a transaction. If you encounter problems, [report your issue in canny](https://bobstablecoin.canny.io/report-issue) and share the Support ID to help us troubleshoot.

### Faster sync for all clients

* We implemented a CDN to serve account history, speeding up the download and decryption sync processes for all users.
* We fixed several bugs impacting parallel execution of WASM code on M1, resulting in improvements to app startup and data population.

### Self-healing feature

The client application now automatically determines if something went wrong with local state and tries to fix it, resulting in fewer manual resets.

### Minor technical updates

* Safari support added. The UI for mobile will be optimized in a future release.
* Rejected transactions are now also shown in the history tab.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zkbob.com/resources/release-notes/january-2-2023.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
