# Nyancat Testnet V0.15
## Latest version: [v0.15.0-rc1](https://github.com/irisnet/irishub/releases/tag/v0.15.0-rc1)
- The point-to-`iris` conversion rate will be announced at the end of this incentivized testnet campaign.
- For every task, only the top 40 validators who completes can get rewards (the upgrade task is based on the voting list of the upgrade proposal, if a valid voter doesn't complete upgrade in time, the reward will be extended to the next completed validator)
In the `v0.15` version, we introduced a new module: [Asset Management](https://github.com/irisnet/irishub/blob/develop/docs/features/asset.md). IRISHub allows individuals and companies to create and distribute their own tokens for any scenario they can imagine.
Since `v0.15.0-rc1` is not a stable version, we will launch a new testnet `nyancat-3` to test and perform tasks, during which we may upgrade one or more times until the final `v0.15.0` is released.
The upgrade of mainnet from `0.14` to `v0.15` is a major event, because this will be the first attempt among BPoS blockchains to perform on-chain software upgrade without stopping the network! So after `v0.15.0` is released, we will propose a new testnet upgrade task, restart `v0.14.3` and upgrade to `v0.15.0` through on-chain governance, and rehearse the entire process of upgrading the mainnet.
