# FLC-2211.25 (WHISTLE Upgrade)

**Fixes and Changes**

* **Simple Mode Strategy Choice:** When the Dapp is set to Advanced Mode “off”, or as us degens call it “simple mode”, the input staking token strategy is now a much simpler *clean as a whistle* UX, and so easy a caveman can do it.
* **APY Values:** A more comprehensive footer output description for APY calculations now shows the dollar value of the input and output. The APY percentages per output token are now displayed directly underneath the primary UI for those output values. This sentence takes longer to read than it would have been if you’d went to go look at the dapp to see these cool new changes for yourself.
* **Flashback Default:** When viewing the Flashback section of the dapp, the default choice is now FLASH/ETH LP tokens instead of FLASH, when the FLASH pool is sold out and has no more rewards since all the cool kids already staked their FLASH.
* **Minor UX Tweaks:** The apes smashing keyboard keys from computers powed by hamster wheel generators have submitted fixes to a few css borders. The future is now!

## 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.flashstake.io/frontend-changelog/2022-changelog/flc-2211.25-whistle-upgrade.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.
