## Release Highlights

### ETH pool support on Optimism

The UI was reworked to allow for multiple pools on multiple chains. The first pool to be released is the [ETH pool on Optimism](/zkbob-overview/zkbob-pools/eth-pool-on-optimism.md), where both ETH and WETH can be deposited via different methods.

### Pending deposits display

ETH deposits use a different method for deposit (direct deposits). These can take longer, and pending display was added to provide users with additional information during an ETH deposit.

### Standards support for new token pools

Support was added to allow for new token pools, including support for the upcoming BOB - USDC migration on Polygon. `Permit2` and `TransferWithAuthorization` (aka EIP-3009) standards were implemented.

## 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/july-13-2023.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.
