# Release Notes - Version 0.9.0¶

🚀Welcome to hummingbot version 0.9.0! Please see below for what's new in this release.

## 🏃 Earn rewards from trading with Liquidity bounties¶

Liquidity bounties are live! We have partnered with Harmony Protocol to launch the $ONE Makers program, which gives ETH-based rewards for Hummingbot users who provide liquidity to Harmony's$ONE token.

To get started, update Hummingbot to v0.9.0 and use the bounty --register command when you run Hummingbot.

## 🔗 New market connector: IDEX¶

With 67% market share (source: dex.watch), IDEX is the most active Ethereum-based decentralized exchange currently. We have worked closely with their team over the past few weeks to build this connector.

Today, we're happy to announce that the IDEX market connector is ready for use, and all Hummingbot strategies should work on IDEX.

## 💻 Multiple orders in the pure market making strategy¶

The pure market making strategy now allows you to place multiple levels of orders on each side of the order book. This allows market makers to set different tiers of orders with different spreads and order amounts.

For information on how to use this new feature, please see the Multiple Orders configuration section.

## 📈 Performance analysis in history command¶

Tracking profits and losses is an essential part of trading. The history command now has a Profitability section which computes your return expressed as a percentage of your starting inventory balance. We will publish a blog post shortly with the methodology of how we calculate performance.

## 🐞 Bug fixes and miscellaneous updates¶
