* Make sure to add the AutoConfig section to `config.js`, see the example config file in the v15 release files.
* Empty your browser cache for your Gunbot GUI (for example with ctrl-F5).
* In case you used https for the GUI, also make sure to copy both the key and certificate files to the new folder.
* If you have pairs that are in DU or RT, also copy the /json folder from your previous installation.
* When you use email alerts, make sure the [syntax of your alerts](/wiki/how-to-work-with-gunbot/extras/tradingview-add-on.md#alert-message-contents) is correct.
* If you also want to migrate your settings for the Telegram bot, copy the `tgconfig.json` file to your new folder as well.

## New features / changes in v15

* **Over 100 new supported exchanges:** Gunbot now [supports](/wiki/about/supported-exchanges.md) spot trading on all exchanges supported by the [ccxt library](https://github.com/ccxt/ccxt/wiki/Exchange-Markets)! This includes support for email alerts through the TradingView add-on.
* **Trading fees setting moves to exchange section:** for easier strategy handling, the TRADING\_FEES setting is now configurable per exchange. It's no longer a strategy setting.
* **Limit orders for TradingView add-on:** optionally you can now let the TradingView add-on place limit orders instead of market orders.
* **Pre-release of AutoConfig:** with [AutoConfig ](/wiki/how-to-work-with-gunbot/extras/autoconfig.md)you can automate all kinds of things you previously could only do by hand. For example you can use it automatically add high volume trading pairs, assign a bag handling strategy for pairs that are not performing well, or automatically update pair overrides. It's called a pre-release because there no GUI for it yet, it's fully functional though.
