## Release Highlights (UI)

### Payment link improvements

Payment links are an important feature for zkBob users. Users requesting private funds can send a payment link to anyone via regular channels like email, telegram, discord etc. When someone receives a payment link they don't need a zkBob account, and can use any token to make a payment. Improvements include:

1. Available tokens and amounts are displayed to users sending a private payment, making it easy to select and send.
2. Transaction confirmation has additional details, and can be downloaded by users.
3. Payment receivers get a notification once they receive payment from a payment link.
4. Payment link now supports both ETH and USDC pools on Optimism.

### Portuguese language support

zkBob is seeing adoption from users around the globe. Portuguese language support was added to the app, and additional language support will be considered in upcoming version.

### Message signing via ledger

A fix to support ledger hardware wallet users when signing messages in zkBob.

## 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/october-11-2023.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.
