Acadia includes all the changes and improvements from Zcash 2.0.2 and brings ZelCash up to date with the latest developments. A big thank you to the Zcash Team
If you have auto update enabled, nothing. Great, right? If you don’t then make sure to download the latest version when prompted. (If you use fullnode, ZelCore will download new binaries and will fetch the new keys required to remain compatible with Acadia (don’t worry it’s all automatic) but don’t worry if you see it redownloading things next time you launch it.)
Also keep an eye out on those updates.
Make sure to update, keep an eye out on the 14th/15th of December a new version will be released, you will need to update to remain compatible. Make sure to backup your wallet.dat before updating but you should of already of done that.
I think you know what you are doing ;) But Acadia is a mandatory update and you will be required to update your Zelcash Daemon and Cli.
