We released a new mainnet version v2.2.0 at https://github.com/nknorg/nkn/releases. This version adds a few major features including client authorization, client message cache, transaction pool sync. In addition, this version contains several performance optimization, bug fixes and security patches. Upgrade is highly recommended.
How to Upgrade
- If you are using nkn-commercial (including one-click on DO/AWS/Google Cloud) or nknx fast deploy, you don’t need to do anything.
- If you downloaded the release version, you just need to download it again at https://github.com/nknorg/nkn/releases, replace files and start nknd again
- If you build from scratch, you just need to do the build again.
- If you are using some scripts or tutorials that has auto-updater, then it should be automatic if the auto-updater is working properly.
We don’t recommend anyone to download the ChainDB snapshot manually, but if you really want or need, you can use https://nkn.org/ChainDB_pruned_latest.zip or https://nkn.org/ChainDB_pruned_latest.tar.gz for pruned ChainDB.
